The rings are provided with blunt spines which are nearly uniform, except on 



the seventh truncal ring and also on the fourth, the 

 seventh, the eleventh and the fourteenth caudal rings, 

 where they are dorsally a little enlarged. The abdomi- 

 nal crista are prominent, in the males they are provided 

 with a black cutaneous fringe (dewlap). There are no 

 cutaneous appendages, except the simple papillae on 

 the breeding-pouch, which are more closely arranged in 

 the posterior half of the pouch. The coronet is scarcely 

 developed. The rostrum is very short and is half to 

 three-fourths in the post-orbital length of the head and 

 up to one and a half times in the orbital diameter. The 

 colour is uniform^ dark : there are light radiating stripes 

 from the eye. Total length up to 70 mm. 



Types : — There were altogether nine specimens from 

 Rambha Bay in the series that Dr. George Duncker 

 examined in describing the species, five males and the 

 remaining four females. The type male specimen is 



registered under No. F ^^ and the type female under No. F £-â££ in the register of 



the Indian Museum. 



Besides these nine specimens, there are in the collection twelve more specimens
