quite distinct from any which have hitherto come under my obser- 

 vation. 



Emys fuliginosus, 



Depressed, flexible, black. Shields convex, rather irregular, with 

 deep, irregular, subconcentric grooves of unequal depression. Under- 

 side black, with white blotches on the front margin of the sternum 

 and on the inner edge of the central marginal plates near the sterno- 

 costal suture, and a small irregular white blotch on the middle of the 

 under side of the front marginal plates. Head rather depressed ; 

 crown covered with a continuous, smooth, rather horny skin. Jaws 

 mottled with sinuous white lines or spots ; sides of the neck with 

 narrow white lines ; the chin and throat mottled with broader white 

 streaks, often interrupted or coalescing, or short and sinuous ; the 

 temple with a distinct round white spot, with two or three small white 

 dots in front of it ; the tympanum with a central white spot, and 

 edged with a white streak in front. Legs and feet black ; the front 

 of the fore legs varied with white irregular streaks or spots, espe- 

 cially on the inner side, and with a white streak down the centre of 

 the upper side of each toe. Toes distinctly webbed ; claws rather 

 elongate, curved, acute, black, with pale edges ; the toes with a single 

 central series of larger scales above. Fore legs with four large 

 conical scales on the outer part of the upper side, and with a cross 

 series of three square scales on the under side of the wrist. The 

 hind legs and feet covered with equal, small triangular scales. Tail

Description of Homalocranium laticeps, a new Snake 

 from Carthagena. By Dr. Albert Gunther. 



A Snake presented by Capt. Garth to the British Museum proves 

 to be a new species. It was procured at Carthagena. 



Homalocranium laticeps. 



Diagnosis. — Scales in fifteen rows. Head broad, depressed as in 

 Maps. Seven upper labial shields, the third and fourth of which 

 enter the orbit ; two posterior oculars. Above black, with about 

 twenty-three narrow brownish-yellow rings, the first forming a collar ; 

 belly brownish-yellow. 



Description. — This Snake much resembles an Maps in general 

 habit ; but there is no fang anteriorly, and the last maxillary tooth is 

 longer than the others, and appears to be grooved. The rostral 

 shield is rather low, triangular, and somewhat bent backwards on 

 the upper surface of the head ; the anterior frontals are much broader 

 than long, and only one-fourth of the size of the posterior ; the ver- 

 tical is six-sided, not much longer than broad ; occipitals moderate. 

 The nostril is between two shields, the anterior of which is the 

 largest ; loreal none ; one anteorbital. Seven upper labial shields, 

 the second of which is in immediate contact with the posterior frontal ;
