“ On the back of a second label in the skull vial there is written, "There is no doubt that this is the type skull. It was returned by H. A. with no. given in orig. descr. G.S.M. Jr." In the catalogue of the U. S. National Museum there is the statement that the type of Rhogeëssa tumida was collected by H. A. Grayson.
The name Rhogeëssa parvula was based on two specimens (Smithsonian Institution Nos. 7841 the type and 7842, in alcohol, collected by Col. Grayson in the Tres Marias Islands off the west coast of Mexico.) ”

“ My comparisons indicate that Rhogeëssa gracilis has larger (longer and wider) ears than R. parvula and R. tumida and that it is specifically distinct from the two last mentioned kinds.
The two other nominal species from Mexico, R. parvula and R. tumida, were named and described by Harrison Allen (Proc. Acad. Nat. Sci. Philadelphia, 1866: 285 and 286, respectively) on the basis of three specimens in the United States National Museum. ”

“ The first two measurements are slightly smaller than the corresponding measurements of any other specimen seen. Nevertheless, the measurements (tail, 30.5; hind foot, 5.3 [after H. Allen, orig. descr.] ) of the [Pg 231] holotype of R. parvula, also from the Tres Marias Islands, show that it was as large as no. ”
