description of the animal is very brief, but positive reference is 

 made to the white outer surface of the ears.^ Another nanfe pub- 

 lished in 1830 is the Lepus mexicanus of Lichtenstein (Ahhandl. 

 K. Akad. Wissensch. Berlin (1827), p. 101, 1830). This is 

 based on a Mexican specimen collected by Deppe, but, as in the 

 case of Wagler's L. callotis, no definite type locality is mentioned. 

 The author, referring to Hernandez, ' ' Citli sive Lepus, ' ' remarks that 

 the description of this animal is so brief that it has been hitherto 

 overlooked, but that it nevertheless refers to a well-marked species 

 characterized by the extreme length and breadth of the ears. 

 ' ' Had he but added, ' ' Lichtenstein continues, ' ' that these ears are 

 dark colored on their anterior half, and on the posterior, less con- 

 spicuous part wholly white, the two colors sharply divided at the 

 middle line, he would have sooner directed attention to an animal 

 that first reached Europe in a shipment from Mr. Deppe, and 

 which is deposited in our museum under the name Lejms mexi- 

 canus."* This description leaves no doubt that Lichtenstein had 

 in hand a member of the white-eared callotis group. Three years 

 later the same animal or a closely related form was described as 

 Lepus nigricaudahis by Bennett (Proc. Zobl. Soc. London, I, p. 

 41, 1833). Concerning the ears of this species the account reads : 

 " These are in front mixed black and yellow, giving a grizzled ap- 

 pearance ; on the hinder part they are entirely ochraceous for about 

 tAvo-thirds of the length of the ear, the terminal third, as well as the 



tip and the hinder fringe, being white " This is one of the 



species " obtained by the [Zoological] Society from that part of 

 Cahfornia which adjoins Mexico." Whatever it may be, it is evi- 

 dent that it is not the animal that I have called Lepus asellus. 

 The last of the names which need to be considered here is the 

 Lepus flavigularis of Wagler (Schreber's Sdugethiere, Supple- 

 mentband, Abth. iv, p. 106, 1844). It is based on a specimen 

 from no certain locality. While there is some doubt as to the

 dunkel gefarbt, in der hinteren (weniger zum Vorscbein kommenden) vollig

 bar und scharf begranzen, so wiirde er die Aufmerksamkeit friiber aiif eiu

 Europa gekouimen und in unserm Museum unter dera Namen Lepus mexi- 

 canus aufgestellt ist.
