Genus 23. PSETTINA. 



Psettina, Hubbs, 1915, Proc. U.S. Nat. .Mus., xlviii, p. 456 [Engyprosopon iijimce, Jordan and Starks]. 

 CrossoUpis, Norraan, 1927, Rec. Ind. Mus., xxix, p. 22 [Arnoglossus brevirictis, Alcock]. 



Very close to Arnoglossus, but the scales strongly ctenoid on ocular side (cf. Crosso- 

 rhombus, p. 217') ; a blunt rostral spine, more prominent in the male ; mouth somewhat 

 smaller, the length of the raaxillan,' 2* to 3J in that of head; teeth all small, scarcely 

 enlarged anteriorly ; gill-rakers rather short and stout. 



Three species from the Indian Ocean and Archipelago and Japan.

advance of upper . . . . . . . .2. iijiinis.

of upper ......... 3. profunda.

* The similarity between the scales of Psettina and Crossorkombus is very striking, and it is 

 possible that the two genera should be united. In view of the marked diflerences in the interorbital 

 region, it seems inadvisable to do this, particularly as the logical outcome would have to be the 

 union of Arnoglossus and Engyprosopon.
