Of the three specimens in the survey collection two are without the black spot 

 behind the opercle said to be characteristic of the species One of these is a young 

 specimen measuring 47 mm. from Rambha Bay ( 2 2- vii- 14), which is without any spot. 

 The specimen from Gopkuda collected on i5-viii-07 measuring 60 mm. is also without 

 the spot. The black spot behind the opercle is very conspicuous in the specimen from 

 Barkul caught about i8-ix-i5. Russel's figure (plate clxxxvi, fig. 1 of vol. ii) does 

 not show the spot nor does his description (p. 70) make any mention of it. Rüssel 

 considered, probably correctly, his fish to beidentical with Willoughby' s figure 2, tab. i 

 of his Ichthyological Appendix — but as he did not describe the fish and Rüssel was 

 first to supply the description under Willoughby's name — Rüssel is the real author 

 of the species for which Willoughby supplied the name and a figure. Rüssel is not 

 quite sure about the local name of the fish and he gives two alternative names (( Kowal 

 or Kowarloo." Day gives Muddecru as its Telugu name. Russel's local names appear 

 to be of the nature of a generic name for small Clupeioids. 



The fish occurs throughout the main area after the freshets. There are altogether 

 four specimens in the collection with the Gopkuda one of 1907. 



Distribution : — Seas and estuaries of India, Burma, Siam, Malay Archipelago and 

 Philippines.

 (Text-figure 3.) 



The dorsal profile is almost straight and the ventral profile is convex from the 

 end of the snout to the origin of the anal fin, from which it is nearly straight to the 

 root of the caudal fin. The shape of the fish is oblong and the body is compressed. 

 The abdominal keel possesses altogether twenty-five scutes beginning from the throat, 

 fifteen of which are preventral and ten behind the root of the ventral fin. 



The height (the greatest depth) of the body is 27 %, L the length of the head 18 5 % ; 



1 Measurements are in hundredths of the length without the caudal fin.
