796 MR. J. LEWIS BONHOTE ON A SMALL [NoV. 9, 



Wroughton, who kindly allowed me to look over MS. notes of 

 his on the genus. 



The measurements of my specimen, an adult female, are : — Head 

 and body 97 mm. ; tail imperf. 60 (certainly shorter than head 

 and body when complete); hind-foot 18 ; ear 16-5. 



Skull. Greatest length 29 mm. ; basal length 24 ; greatest 

 breadth 15 ; length of molar series 5 ; length of diastema 7 ; 

 length of palate to henselion 23 ; length of nasals 11 '5, 



This is apparently a very scarce and local species. The type 

 locality is Sinai, and Tristram found it near Massada at the 

 southern end of the Dead Sea but not elsewhere in Palestine, and 

 since then it does not seem to have been brought home by any 

 collector. There is a specimen of Burton's in the Museum which 

 has been referred to this species, but it is in such a bad state that 

 identification is quite impossible. 



It is certainly curious that this species, occurring so nea,r Cairo, 

 should never have been brought in by local Bedouins, but the 

 fact that a second visit to the locality with two men to dig did not 

 result in any further examples of this species, but brought to 

 light two individuals of the new Dipodillus described in this 

 paper, tends to show that the particular locality is certainly 

 unworked either by natives or collectors and that such mammals 

 may escape observation even when searched for *.

This species is frequently brought in from the desert near 

 Cairo. It is smaller and yellower in general coloration than the 

 next species.

The southern form of this species seems paler and rather larger 

 than the typical race from Egypt. A single specimen from 

 Khartoum, the type locality, was brought back.

A single example of this Desert Hare was shot by Mr. M. J. 

 Nicoll in the desert near Aburoash. It was originally described 

 from Gattah in the Fayum, so that this record extends its range to 

 the north. One of the most distinctive points of this species is 

 the long white hairs on the flanks and sides of the body. 



The measurements of this specimen (a female) were : — Head and 



* Since the above was written Mr. NicoU informs me that he has procured another 

 example of this species in the Wadi Hot near Helouan.
