Hob. Old Calabar, W, Africa j //'. Logan, Esq.). 



Since this paper was read, I have discovered a young specimen of 

 this P»oa among the specimens from the Zoological Society, which 

 they had received from Fernando Po. ' It is about half the length 

 and diameter of the specimen from Old Calabar. It h,;^ the head- 

 Bhields more uniform, and as I supposed they might be when I de- 

 scribed that specimen. 



It has three pairs of band-like frontal shields over the forehead, 

 a rather large parietal shield behind them on the crown of the head, 

 and two small Bubequal superciliary shields between the outer edge 

 of the parietal and the eye, on each side, a narrow transverse band- 

 like central shield behind, and rather broader than the parietal 

 shield, with a small scale-like shield, like those on the neck, behind 

 and on the sides of it. 



Having had occasion to look through many papers by Dr. Edward 

 Ilallowell, on the Reptiles of Liberia and Gaboon, in the 'Journal 

 of the Academy of Natural Sciences of Philadelphia,' to find if tin- 

 above Boiilce and other reptiles in Calabar had been described, 1 

 have been induced to prepare a list of the Reptiles and Batrachians 

 which have hitherto been recorded as inhabiting Western Africa, 

 giving a reference to where the species have been described, and the 

 special habitat of the species noticed.
