marking on the occiput. Lower parts yellowish and black; 

 the black coloiir is arranged in two rows of great sqnare 

 spöts which on the posterior part of the trunk, alternating 

 with each other, form a broad zig-zag line; on the anterior 

 part as also on the tail these spöts confluent into broad ob- 

 lique cross bands, which on the tail and on the throat are 

 narrower, but on other parts as broad as or broader than the 

 light interspaces between them. 



As shown above, this species agrees rather well in colour 

 with other species of Ungalia, hitherto described, from which, 

 however, it is beside other characters distinctly separated 

 by its broad vertebral row of scales and by the small nuniber 

 of scale-rows, characters not coincident in any other Ungalia- 

 species. 



The specimen in question belongs to the collection from 

 Doctor TouzET. The labels belonging to this collection are 

 marked »Brasilia». The new Ungalia would then differ even 

 in the geographical distribution from other f7w^«Zia-species, 

 hitherto kuown, the patria of which is the West Indies, the 

 Central America, and the west Sonth America. 



The single specimen is a female.

Among the fine collection of snakes which the Royal 

 Museum in 1885 received from Mapanja, Cameroon, from 

 Messrs. Knutson and Valdau, there were six specimens, evi- 

 dently belonging to the same genus, which on account of 

 the form of the teeth ought to be closely allied to the genus 

 Boodon. By a deep loreal pit, however, the specimens in 

 question are distinctly separated from this genus and neared 

 to Botlirolycus as also to Bothrophthalmus, although they gene- 

 rically differ from these in the teeth. On these reasons, 

 when cataloguising the snakes of the museum, I came to the 

 conclusion that those six specimens, which evidently represented 



^ Length of the head (distance between the nose and the hind margin 

 of the parietals) 8 mm. Greatest breadth of the head 6,8 mm. Longitudinal 

 diameter of the eye 2 mm. Distance from the eye to the snout 3,6 mm.
