Height 5 1; head 5.5 — 6; eye 18 — 20; snout 2.7 in head. 

 Rays of dorsal shorter than those of anal. Pectorals very small, 

 equal to eye. The distance of anus from vertical through 

 pectoral is "^/g of the postorbital part of the head. Colour silvery 

 with small black spots. Length 560 mm. [After Brauer and 

 Garman, not seen by us]. 



Habitat: Near West coast of Sumatra (1280 M. Valdivia 

 Expedition). — Indie (12 13 — 2400 M.); Pacific. 



Note: Gilbert (Bull. U.S. Fish Comm. XXIII (1903) 1905, 

 part II. p. 586), Brauer (1. s. c.) and Lloyd (1. s. c.) suppose, 

 that this species is identical with Serrivofner beani Gill & Ryder, 

 (Proc. U.S. Nat. Mus. VI. (1883) 1884, p. 260). But 5. beani 

 has only 138 rays in the anal and its height is only 29.7 in 

 the length according to GiLL & Ryder. If this difference 

 from 5. sector is constant, we are of opinion that both species 

 are valid. Otherwise the name beani has preference as being 

 the older.
