“ Several kinds of bats, of which we lack records, certainly occur in Michoacán. Four or five kinds of cats (genus Felis) , species of the genera Potos, Lutra, Tayra, Grison, and several other kinds of mammals of which we now lack positive record, also probably occur there; the list of kinds, we expect, will number more than one hundred species and subspecies when more intensive collecting has been done in the state. ”

“ Remarks.—Specimens from Los Reyes referred to the subspecies P. b. vicinior by Osgood (1909:209-210) were later characterized by Osgood (1945:300) as agreeing with specimens from Zitácuaro, and Osgood (loc. cit.) thought that those from both Los Reyes and Zitácuaro were not P. b. vicinior but possibly P. b. banderanus. He had this material set aside for further study when he showed it to one of us (Hall) in 1945. It was his intention to revise the entire species (P. banderanus) but so far we know never did this before his death.

“ The habit of burrowing at different levels probably was one factor which permitted the two kinds of pocket gophers to live in the same area. The average weight of these gophers was 86 grams in males and 74 grams in females, or only an eighth as much as in Cratogeomys.

“ Cranial measurements average approximately 5 per cent larger in males except that the breadth of the rostrum and length of the maxillary tooth-row are slightly less. South and east of Tacámbaro our specimens all were taken in dry semitropical country, where bananas and sugar cane were the principal crops grown. This subspecies has been recorded also from La Huacana, Michoacán, as well as from La Salada, the type locality, by Goldman (1911:39) .

“ Specimen no. 945b has M3 present on both sides of the upper jaw. From Artibeus hirsutus, known from La Salada, Michoacán, approximately 40 miles north and slightly to the east of El Guayabo, our specimen differs in the apparently hairless tibia and interfemoral membrane. The measurements, of no. 945b, recorded above, if compared with those given by Andersen (1908:246) are seen mostly to fall within the range recorded for A. hirsutus. ”

“ The four other specimens in darker immature pelage are plumbeous and cinnamon whereas immature individuals of comparable age of Peromyscus banderanus caught in the same place are plumbeous above and lack the cinnamon color. The immature animals of the two species differ in color more than do the adults. Osgood (1945:300) has recorded eleven specimens from the type locality. Our one adult weighs 52.4 grams.

“ The shorter tooth-row at the lower elevation (Tacámbaro) , we interpret as intergradation with Oryzomys couesi mexicanus. In color the specimens from Tacámbaro are, to us, indistinguishable from those from Zamora and Pátzcuaro but the color is notably darker than that of specimens from the vicinity of Apatzingan which are here referred to the subspecies [465] Oryzomys couesi mexicanus. The largest male, fully adult from Zamora weighs 82.9 grams and the largest one from the vicinity of Tacámbaro weighs 73.6 grams.

“ NW Pátzcuaro, 6,700 ft.
Remarks.—La Salada and three miles northwest of Pátzcuaro are the two localities represented by actual specimens. A live animal, at night, was seen one mile east and four miles south of Tacámbaro at 4,500 feet elevation. The young female from three miles northwest of Pátzcuaro was trapped at a break in a stone fence.
Ring-tailed cats live in the stone walls, crevices and rocky ledges, around corn fields and pasture lands.

“ In the color of the underparts the series is, to us, indistinguishable from topotypical toltecus and therefore has more reddish underparts than [459] R. f. tenuis, as we know R. f. tenuis, from Howell's (loc. cit.) description. In size, the series from Pátzcuaro is intermediate between R. f. tenuis and R. f. toltecus but nearer the latter.

“ Mus musculus Linnaeus, Systema Naturae, ed. 10, 1:62, 1758, type from Upsala, Sweden.
Range.—Probably throughout state.
Specimens examined, 4: nos. 100696-100699, of which one is from Tacámbaro, 5,700 ft., and 3 are from 4 mi. S and 1 mi. E Tacámbaro, 4,500 ft.
Remarks.—In each of our specimens the belly is dark, approximately as dark as the back. The specimens caught by us were living in the wild; that is to say, they were not caught in and around buildings. Elliot (1903:141) records the species from Pátzcuaro.

“ W Apatzingan, 1,040 ft., 1.
Remarks.—In allusion to its habit of washing its food, in captivity at least, before eating it, the Spanish speaking people often refer to this species as ositos labadores. The specimen from 10 mi. ESE Zamora is a skull without lower jaws or indication of sex. Because the racoons damage corn in the roasting ear stage the animals are disliked by the farmers, a score of whom sometimes band together in an organized hunt to kill the animals. Dogs are especially trained to hunt them. In Michoacán no use is made of the pelts.

“ This continuing interest in the mammals of Michoacán has made it seem, to us, the more desirable to place on record our findings as to kinds and occurrence of species. In doing this we have examined the collections made previously on Cerro Tancítaro and vicinity by the field party led by Mr. Harry Hoogstraal from the University of Illinois and the Chicago Natural History Museum. The specimens of mammals collected by this field party are in the Chicago Natural History Museum and we are obliged to Mr. ”

“ Remarks.—Under date of October 11, 1948, Henry W. Setzer (in litt.) states that four specimens of this species, in the Biological Surveys Collection in the United States National Museum, were taken at La Salada, by Nelson and Goldman, and bear catalogue numbers 126156, 126157, 126158 and 126159. No. 126158 is a female taken on March 19, 1903. The other three specimens are [470] males taken on March 17, 1903. We did not see any animals of this species in our own field work, and the only materials from Michoacán actually examined by one of us (Hall) are the skulls of nos. ”

“ Goldman, Proc. Biol. Soc. Washington, 55:79, June 25, 1942.
Range.—Probably all but higher parts of state.
Remarks.—We have no positive record of this animal which Goldman (1942:79) writes "is widely distributed from Jalisco south through Colima, Michoacán, ... to southwestern Oaxaca." [447] In the parts of Michoacán visited by us the Spanish name tejón instead of pizote was used for this animal although in parts of México where the badger (Taxidea) occurs, tejón is, we understand, the name used for the badger.
