upper surface is grayish to nearly uniform brown; the fingers and 

 toes are barred. 



The position of the nostril varies a little; in most specimens it is 

 slightly below the canthus rostralis. Males have 2 or 3 rows of anal 

 pores. 



Varanus niloticus (Linnaeus). 



Kisumu. One specimen. Body 100 mm., tail 140 mm. 



Eremias spekii Giinther. 



Voi. Six specimens of about uniform size, the two perfect speci- 

 mens measure as follows: Body 48 mm., tail 85 mm.; body 

 47 mm., tail 78 mm. 



Qerrhosaurus flavigularis Weigman. 



Nairobi. Body 140 mm., head 26 mm., width of head 18 mm., 

 arm 37 mm., leg 60 mm., tail 225 mm. (tail not perfect, and with a 

 bud or branch 5 mm. in length 35 mm. from its tip), scales 8-20- 

 56, femoral pores 12; body 122 mm., head 24 mm., width of head 



18 mm., arm 37 mm., leg 60 mm., tail 292 mm., scales 8-22-58, 

 femoral pores 14 and 15; body 145 mm., head 32 mm., width of head 

 23 mm., arm 36 mm., leg 69 mm., tail 310 mm., scales 8-22-57, 

 femoral pores 16. 



The squamation of the head of these three specimens is the same. 

 Fronto-nasals not touching rostral ; prefrontals forming a suture about 

 equal in length to fronto-nasal ; frontal nearly twice as long as broad 

 and as long as its distance to rostral ; fronto-parietals forming a suture ; 

 interparietal very small; parietals forming a suture behind inter- 

 parietal twice the length of this scale. 



Brownish above, a light narrow median and a broader light black- 

 edged line on each side extending from nostril and upper margin of 

 eye, fading out near middle of length of tail ; sides with narrow bars 

 composed of light and dark spots; belly light; upper surface of head 

 marbled with darker. In point of scales these specimens more nearly 

 agree with G. nigrolineatus as described by Dr. Boulenger, which is 

 regarded as a synonym of G. flavigularis by Tornier. 



Gerrhosaurus major Dumeril. 



Voi. One specimen. Body 88 mm., head 22 mm., width of head 



19 mm., arm 29 mm., leg 40 mm., tail 119 mm., scales 32 in trans- 

 verse series, 12 longitudinal series, ventrals in 10 series, 13 femoral 

 pores. Scales on top of head slightly rugose; fronto-nasal broader
