 pressed lobe covered with scales. Chin simple ; orbit rounded. 

 Back rounded, with a series of small, distant, slender, flexible, single

1. Crassonota nasuta. B.M. 



Chameleo nasutus, Gray, Cat. B. M. 268 ; A. Smith, Zool. S. 

 Africa, App. 3 ; A. Dum. Arch, du Mus. vi. t. 22. f. 4 (head bad). 



Chamceleon nasutus, Fitz. Syst. Rept. 42. 



Pale brown ; belly paler ; head and limbs white-spotted. 



Sab. Madagascar. 



Var. " With three isolated spines, each about a line in length, on 

 the vertebral line, about midway between the head and the base of 

 the tail. 



" Hab. Eastward of Port Natal. 



" Length : head and body I inch 1 lines ; tail 1 inch 9 lines. 

 Appears to be an adult." (A, Smith, 1. c.) 



11. Ensirostris. 



Nose (of male, at least) with a single central compressed bony 

 horn, sharp-edged above. Orbit rounded. Chin and belly simple, 

 not dentated. Back and tail with a high crest of roundish lobes 

 covered with scales. Occiput keeled, acutely produced behind, shel- 

 ving on the sides, and with a broad hood-like lobe covered with scales 

 on each side behind ; scales unequal, granular, with larger rounded 

 scattered tubercles. 



1. Ensirostris Melleri. B.M. 



Stuffed, grey-brown, with whitish cross bands on the body. 



Hab. E. Africa, on the mountains in the interior (Dr. Metier). 

 A single specimen, probably a male. 



The head and hood are somewhat like those of Calumma cucullata ; 

 but the back -crest and the scales are very different, too different to 

 be sexes of the same species, as I was once inclined to think they 

 might be. 



12. Sauroceras. 



Nose (of male, at least) with a single central elongated bony horn, 

 with a deep angular channel on the upper, and a sharp edge on the 

 lower side. Orbit rounded. Back rather compressed, with a series 

 of compressed conical scales. Tail compressed above. Occiput 

 keeled, acutely produced behind, shelving on the sides, with a raised 

 edge below, covered with small scales behind. Scales unequal, gra- 

 nular, with large interspersed tubercles.
