1896.] A. Alcock — Supplementary List of Indian Fishes. 305 



Nine very short pyloric ceeca and two or three papillae : a stout- 

 walled air-bladder. 



Colours sepia ; caudal, distal two-thirds of pectoral, and outer 

 part of dorsal and anal fins black. 



Off Ceylon 296-320 fms., and off Travancore coast, 406 fms. This 

 species is very closely related to Neohythites {Monomitopus) nigrijpinnis. 



5. •\ Bermatorus melampeplus, n. sp. 



At once distinguished from Dermatorus tricliiurus and melanocephalus 

 (1) by the complete absence of teeth on the vomer, and (2) by its 

 uniform purple-black colour. 



In the other two species there are a few scattered teeth on the 

 vomer, and the head alone is black. 



The single specimen has been too much damaged for description, 

 but it is undoubtedly a good species. 



Laccadive Sea, 931 fms. 



Family Pleuronectidse. 



BoopSETTA, n. gen. 



Cleft of the mouth narrow : teeth in the jaws only, in broadish 

 villiform bands on the blind side, gradually becoming obsolescent on 

 the coloured side. Eyes on the right side, very large, almost in contact, 

 the upper bulging beyond the dorsal profile, the lower in advance of the 

 upper. The dorsal fin begins above the after part of the upper eye. Both 

 pectorals and both ventrals well developed. Scales of moderate size, 

 stout ctenoid and adherent on the coloured side, thin cycloid and deciduous 

 on the blind side. Lateral line with a strong curve above the pectoral. 



Gill-openings somewhat contracted, the membranes very broadly 

 united below the isthmus : gill-rakers styliform. 



Closely allied to Fleuronectes. 



6. § Boopsetta umhrarum, n. sp. 

 B. 6. D. 60. A. 51. C. 18. F. d. 8, s. 6. V. 6. L. lat. arc. 110. 



Height of the body one-third, length of the head one-fourth the 

 total, without the caudal. 



The mouth is short and broad, the cleft approaching the vertical, 

 the maxilla being a little over three-fourths the length of the eye, 

 which is slightly over one-third the length of the head. The teeth 

 are in broad villiform bands in the jaws on the blind side, the banda 

 gradually becoming narrow and disappearing on the coloured side. 

 The upper eye bulges very strongly beyond the general dorsal profile.
