222 SPOLIA ZEYLANICA. 



Centropages tenuiremis, Sewell, 1912, p. 363. PI. XXIV., 



figs. 6-7. 



This species has now been reported from the Arabian Sea, 

 the coastal waters of Ceylon, and the coast of Burma. It was 

 present in several of the tow-nettings from the pearl banks, 

 but never in any considerable numbers.

Several examples of this species were taken in a tow-netting 

 at Kilakarai at the head of the Gulf of Mannar. As I have 

 already pointed out {loc. cit.), the descriptions given by 

 Thompson & Scott and Cleve differ in several details ; the 

 present specimens agree exactly with those from the Persian 

 Gulf and from Burma.
