clearly iudic-ittes wliicli species is meant bj- the name ample.vicau- 

 (lata. — A brief diagDOsis of the genus Xanthnrpiiia was given by 

 Gray in Voyage of the ' Sulphur,' i. p. 29 {1844): distinguished 

 from Eleutherurn by having the " tail with the base inclosed in 

 the underside of the interfcmoral meml^rane." 



Eleutheriira, Grray; 1844. — First occurrence of the name in Gray's 

 List Marara. B. M. p. xix (1843): no description, no species. 

 Second occurrence in Voyage of the ' Sulphur,' i. p. 29 (1844) : 

 type (only species mentioned), E. hnUentotta, Temm. ; a brief 

 diagnosis showing that Gray based the genus on Temminck's 

 erroneous description of Ptero'pus hottentottus : tail free (not con- 

 nected with interfemoral), projecting from " a nick on the middle 

 of the narrow interfemoral"; but Temminck's Pi. hoUeniotius is 

 A. Smith's /'t. Jearln. 



Ci/noiii/cteris, Peters ; 1852. — Type (only species mentioned) : 

 Pieropus coUnris, Licht. (nee ill.), i. e. Pteropiis Icachi, A. Smith. — 

 The genus Cjfnoru/cterh, as understood by Peters in 1867 (Kevision 

 of Megachiroptera, MB. Akad. Berlin, 18G7, ])p. 86.5-866), included 

 all the then known species of liousettus and Eidolon. Dobson's 

 Ci/nonj/ctens (Cat. Chir. 1878) corresponds to the genera Eidolon, 

 liousettus, and Mi/oni/cteris of this Catalogue. 



Senoni/cteris, Gray ; 1870. — A subgenus of Xantlmrpiiia. Typo 

 (only species) : Xantharpyia scminuda, Gray. Separated from 

 Xantharpijia s. str. on account of its "very sparse and s'hort " 

 fur, "especially on the back," and " nearly bald" forearm.
