thinner than in N. tessellata and N. delalandii, li to li as long as 

 head and body.* Colour brown above, with small indistinct blackish 

 spots ; bluish-white beneath." 



Distinguished from N. delalandii by the smaller size, the smaller 

 and pointed dorsal scales, fewer ventrals, and the shorter foot. 



Lubreno, Usoga, East Africa (two specimens). 



This species, which is only known to me from the above description, 

 appears to be perfectly distinct. 



A third specimen, a male, 63 mm. long from snout to vent, from 

 Lake Victoria, has since been described by Sternfeld. 51 scales round 

 the body, ventrals in 8 longitudinal and 34 transverse series, 12 

 femoral pores on each side. A fourth, from the Eldama Eiver, East 

 Africa, with 10-11 femoral pores, has been noticed by Nieden.

Head small, slightly broader than deep, \^ to If times as long as 

 broad, its length 4 to 4^ times in length to vent; snout obtuse. 

 Pileus 21 times as long as broad. Body feebly depressed. Limbs 

 moderate, the hind limb reaching the wrist or the elbow ; foot as long 

 as the head ; digits feebly compressed. Tail tapering from, the base, 

 11 to 2-1- times as long as head and body. 



* Tail probably regenerated. In the specimen noticed by Nieden it is nearly 

 twice as long as head and body. 



t The type specimen, described by A. Smith and by Dumeril and Bibron, 

 was presented to the British Museum by the former author in 1865, under the 

 name of L. delalandii, along with the types of the other Nucras in his private 

 collection, and its absolute concordance with the original description was over- 

 looked by me when, following Smith himself, I placed L. intertexta in the 

 synonymy of N. delalandii. Although not labelled as such, the specimen is 

 certainly A. Smith's type. It was referred by me to N. tessellata.
