Rhinolophus acrotis braclnjgnathas, subsp. n. 



Diagnosis. — Like Rh. acrotis Andersoni, but \ippcv and 

 lower tooth-rowSj as uell as mandible, distinctly shorter. 



Skull and dentition (two skulls examined). — Altliougli 

 being apparently, on an average, larger than Rh. a. Andersoni, 

 the present form has a smaller skull, smaller teeth, shorter 

 tooth-rows and mandible (conf. measurements). 



Colour. — The general colour of the single skin at my 

 disposal ( ? imm.) is much darker than in the type of 

 ]Ui. a. Andersoni ( S iinni.) : grej ish '^ drab" on the upper- 

 side, tinged with " mouse-grey " on the hinder back ; 

 '' ecru-drab " on the underside ; base of hairs on the back 

 of the same colour as the underside. 



Ty])e. — S ad. (in alcohol). Ghizeh, Lower Egypt, Dec. 

 16tli, 1891 ; collected and presented by Dr. J. Anderson. 

 B. M. no. 92. 9. 9. 7. There is a second specimen ( ? inim., 

 skin) in the jNIuseum from the same locality. 



Distribution. — Known only from Ghizeh. 



Remarks. — The absence, even in immature individuals, of 

 the lower />3 and upper /y'^ distinguishes this form sufficiently 

 fi'om the only species with which it could possibly be 

 confounded, viz. Rh. euryale and Rh. cUvosus. 



Up to the present time three forms of Rh. acrotis have 

 been described : Rh. acrotis (typicus) from Keren, Erytrea ; 

 Rh. a. Anrlersoni from the Eastern Egyptian Desert, about 

 22° N., 35° E. ; and Rh. a. hrachygnaihus from the environs 

 of Cairo.
