50 PROCEEDINGS OF THE ACADEMY OF 



Coloration. Head oli\'e colored above, spotted with black ; two yellow stripes, 

 one on each side of the back commencing at the occiput, and lost nearly mid- 

 way upon the tail, bordered with a band of black internally ; interspace olive, 

 black spotted, having the appearance of lines upon the tail ; extremities 

 olive colored above, posterior part of thighs yellow spotted ; abdomen ccerulean 

 blue ; the remainder of the under surface yellowish. Young white spotted upou 

 the sides upon a bluish ground, and a double row of white spots along the back 

 between the black colored bands ; sides of tail white or yellow spotted. 



Dimemions. Length of head 10 lines ; greatest breadth 6 ; of head and body to 

 vent 2 inch. 10 lines. Total length including tail 11 inch. 5 lines. 



Habitat. Gaboon. Two specimens, adult and young.

Proceed. Acad. N. S., vol. vi. p. 62. The length of this specimen is 1 ft. 2} 

 inches ; of tail 1 inch 4 lines. A very singular looking animal. The contrast 

 between the narrow mosaic looking quadrangular scutes upon the back, and 

 the two longitudinal rows of broader ones is quite striking; the tail is short 

 and rounded at its posterior extremity, which is protected by a circular mamme- 

 lonated shield. The figure of the plate in the wood-cut of the nostrils in the volume 

 of the Proceedings referred to, does not appear to be accurate, this plate being 

 more extended longitudinally, reaching to the extreme end of the rostral, where it 

 is quite narrow terminating almost in a point. The single lateral pore on each 

 side of the preanal scutes is very distinct and is no doubt a constant character. 

 This species appears to be allied to the Cephalopeltis Cuvierii of Miiller, 

 which has two plates upon the top of the head, (Zeitschriftfur Physiologie, von 

 F. Tiedemann, G. R. & L. C. Treviranus, Vierter Band. Erstes Heft. 1831, 

 Taf. xxii, iig. 5, a, b, c. Dr. Smith in speaking of Monopeltis capensis observes, 

 that although I have put forward this species as a type of the group, I doubt if its 

 more extended observation will justify the proceeding. It may prove to be only 

 a very aberrant species of Lepidosternon, and if so Cephalopeltis Cuvieri, Miiller, 

 will be a species of the same group, only a degree less removed from the typical 

 form. The most marked difference between the species in question and Lepi- 

 dosternon macrocephalum, Wagl., consists in the covering of the head ; in the 

 latter it is formed of many plates, in Cephalopeltis of two only, and in Mono- 

 peltis of one. (Illustrations of S. African Zoology, Reptiles, pi. xvii.)

Proc. Acad. N. S., vol. ii. p. 5S. Six specimens, (four adult,) (one immature,) 

 (one quite young.) 



In a specimen from Liberia, the white stripe extends about half way along 

 the side of the body, but it is more extended on the opposite side, and in all the 

 specimens from the Gaboon there are two white vittae on each side, the lower 

 one commencing in front of the eye and terminating at the posterior extremity ; 

 the upper one beginning at the occiput and reaching as far as the root of the 

 tail, the lower band the broader of the two ; four narrow black lines along the 

 back, two on each side, becoming lost upon the root of the tail where they as- 

 sume more the form of spots ; the row of white spots passing along the side 

 of the neck and body as far as the extremity of the tail mentioned in the former 

 description, is no doubt identical with the upper lateral vitta; under surface 

 immaculate. I do not observe that the inter-parietal is larger than either of 

 the fronto-parietals in any of the specimens; in the one from Liberia it is 

 longer. In all the Gaboon specimens the fronto-nasal are separate; in the one 

 from Liberia they are almost in contact.
