Measwements. — Averages and extremes of nine males and three fe- 

 males from 8 miles southwest of Cairo, at the Pyramids, were, re- 

 spectively : Total length 135 (128-143), 131 (125-138) ; length of tail 



68.0 (64.0-73.0), 65.0 (61.0-70.0) ; length of forearm 57.5 (55.0- 60.0), 

 55.3 (53.0-57.0) ; length of hind foot 13.3 (13.0-14.0), 13.3 (13.0-14.0) ; 

 length of ear from notch 19.0 (18.0-20.0), 19.3 (18.0-21.0) ; greatest 

 length of skull 18.1 (17.9-18.4), 17.6 (17.2-17.9) ; condylobasal length 



16.1 (15.9-16.2), 15.6 (15.5-15.7); occipitonasal length 14.9 (14.7- 

 15.1), 14.4 (14.2-14.6); greatest zygomatic width 10.4 (10.2-10.7), 

 10.36 (10.3-10.4) ; width of braincase 7.6 (7.4-7.7), 7.3 (7.3) ; canine 

 to M^ 6.3 (6.2-6.4), 6.0 (5.9-6.1). 



Remarks. — The specimens listed above vary in some detail from the 

 measurements given by Thomas in his description of the species. 

 These measurements of the Cairo specimens are all somewhat larger 

 but are definitely smaller than those given for the larger species 

 Rhinopoma microphyllum. Thanks to C. C. Sanborn, curator of mam- 

 mals, Chicago Natural History Museum, measurements of specimens 

 of R. cy stops from various localities throughout the Middle East have 

 b^en made available to me. A topotypical series of 17 specimens of 

 R. cystops are only slightly smaller than the measurements given for 

 the Cairo series above. It is apparent that Flower (1932, p. 385) was 

 in actuality comparing specimens of R. cystops from the type locality 

 and from the Cairo area. He thus arrived at the conclusion that R. 

 cystops was conspecific with R. uncrophyllmn. That this conspecific- 

 ity is not real is shown by a comparison of the measurements listed 

 for the two species in the present paper. 



The two species were found together, by Tomich, at the Pyramids 

 of Giza. Among these specimens the larger, darker R. microphyllum 

 is easily differentiated.
