1. Stenodacttlus dobi^ Blanf. 



Three specimens from the Abian country. One, an adult 

 female, the largest of the species I have seen, measures 60 mm. 

 from the snout to the vent, and the tail 46 mm. The second 

 female is about half -grown ; the third is a male, also young. It 

 has two well-developed preanal pores. All three were collected 

 by Mr. Percival in the Abian country. 



The adult female has well-defined large brown spots on the 

 back and much smaller whitish ocelli, margined with brown, inter- 

 mixed among the brown speckling. The other two individuals 

 have no large brown dorsal spots, but the pale brownish of the 

 back is marked by numerous round white spots, with a dark ring 

 encirchng each, intermixed among the dark rings and dark brown 

 speckling. The coloration is much the same as that of the Egyptian 

 S. elegcms, from which this form differs chiefly by the divided 

 character of the scales or plates on the under surface of the toes. 



2. BuNOPUS SPATALTJEUS, sp. n. (Plate XIV. fig. 1.) 



Head oval, flattened from between the eyes and backwards to 

 the occiput. Snout short and somewhat broad, its length equalling 

 once and a half the longitudinal diameter of the eye and one-third 

 the total length of the head on the upper surface. Eorehead 

 convex ; a short depression behind each nostril. Eye rather large, 

 its longitudinal diameter equal to the distance between the hinder 

 border of the ear and external canthus. Ear a narrow oval 

 slit placed obliquely, from above downwards and forwards, about 

 half the long diameter of the eye. Body not depressed but 

 rather compressed, covered with somewhat imbricate or juxtaposed 

 scales of irregular size, the larger more numerous than the
