(in the district of Khulna) in 10 fathoms water, two species of 
Cynoglossus were obtained which are here described as new. 
Cynoglossus acinaces, sp. nov. 
1D; 008-162) Vi255 GAs 120-1a 5s Cem 2 el ale 202133: 
Two lateral lines on coloured side, one on blind side. Scales 
between lateral lines on left side, where widest apart, 13. Length 
of head 5} times, height of body 7 times, in total length. Eyes 
in middle of head; diameter 16 to 17 times in length of head; 
upper slightly in advance of lower and about }§ diameter apart. 
Cleft of mouth extending well behind posterior edge of eyes. 
Scales markedly ctenoid on coloured side, cycloid on uncoloured 
side. 
Colour.—Pale greyish white. 
This species comes nearest to C. elongatus, Giinth., and to 
C. lingua, Ham. Buch. It however differs from both in the much 
larger number of rays in the dorsal and anal fins and in the 
greater slenderness of the body.

Two lateral lines on the coloured, one on the blind side. 
Scales on left side between lateral lines, where widest apart, 
12. Length of head nearly 5 times, height of body 4 to 4°3 times, 
in total length. Eyes in anterior half of head : diameter 22 times 
in length of head ; upper partly in advance of lower and a diameter 
apart. Cleft of mouth extending well behind posterior edge of 
eyes. Scales ctenoid on both sides. 
Colour.—Pale yellow. 
This species comes nearest to C. lida, Bleek., and C. bengal- 
ensis, Bleek. It differs from, the latter in that its ventral fin 
is separate from the anal, and in its body being somewhat more 
slender. From C. lida it is differentiated by the smaller number 
of rays in the dorsal and anal fins. 
IV.—ON A COLLECTION OF FISH FROM KARACHI, WITH A DESCRIP- 
TION OF TWO NEW PLEURONECTIDS. 
This collection of fish was obtained by purchase from Karachi 
in 1908 (February to May). Most of the specimens were bought 
in the markets, but in a few instances inedible species were collec- 
ted from the fishermen. For the most part the collection consists 
of common species. The Pleuronectide comprise two forms which 
are here described as new. The arrangement adopted is that of 
Day as being the most convenient for reference. All the fish were 
Teleosteans.
