2/8 MR. R. F. TOMES ON A COLLECTION [Juiie 25, 



able to realize the differences by actual comparison of specimens." — 

 P. Z. S. 1848, p. 34. But to show how little these describers knew 

 of the perfect animal, I may state that an adult male black Chim- 

 panzee was offered by Mr. Henry Stutchbury to the British Museum 

 as "an adult female Gorilla ; " and this specimen was afterwards 

 purchased by a foreign Museum, and has been exhibited since iis 

 a "Gorilla." — See Commission on the British Museum, 1849, App. 

 No. 19, p. 12. 



For not belie-ving that this black animal was a " Gorilla," I have 

 been represented as doubting the distinctness of the species. 



On the other hand I may state that a specimen of a young Gorilla 

 was exhibited for some months in "Womb well's Menagerie in the North 

 of England as a Chimpanzee, and was as tame and tractable as the 

 young of that animal usually are. This specimen is now preserved 

 at Walton Hall, Wakefield. 



6. Report of a Collection of Mammals made by Osbert 

 Salvin, Esq., E.Z.S., at Duenas, Guatemala; with Notes 

 on some of the Species, by Mr. Eraser. By Robert F. 

 Tomes, Corr. Mem. Z.S. 



(Plate XXXI.) 



1. Desmodus rtjfus, Pr. Max. 



A great many specimens have been brouglit home by ]\Ir. Sahdn, 

 and a smaller number by INIr, Fraser. The latter gentleman says, 

 " Native name Mia-cilaffo, very common. I find nothing but blood 

 in the intestines and stomach. My mule is bitten ever}' night ; can- 

 not say by what." 



2. Glossophaga leachi, Gray, sp. 



Monophyllus leachii. Gray, Zool.Voy. Sulph. Mamm. p. 18, 1843. 



Of this species I find but one specimen in the collection. This I 

 think somewhat remarkable, as it is abundant in Central America, 

 and has a considerable geographical range. Great numbers have 

 been collected in Mexico, and forwarded to Europe by M. Sall6. 



3. Sturnira ?, n. s. 



The head of a small species with white facial stripes, somewhat 

 like those of Arctibeus lineatus. It is smaller in size than Sturnira 

 UUum, and has a rather more obtuse muzzle. 



?4. SCOTOPHILUS URSINUS. 



Vesperiilio ursinus, Temminck & Le Conte. 



Vespertilio carotinensis, Geoffroy. 



The types of F. carolinensis contained in the Paris IMuseum pre- 

 sent two' distinct varieties, which however appear to vary in no other 

 respects than that of size. The larger one has been subsequently 

 called Vespertilio wsinus by M. Temminck ; and in this separation
