Type.— Cat. No. 70249, U.S.N.M., 5.9 cm. in length, taken with 

 abeam trawl at station 5442 (lat. 16° 30' 36" N.; long. 120° 11' 06" 

 E.), west coast of Luzon, at a depth of 45 fathoms, on a bottom of 

 coral sand. 



Of 7 cotypes 4.6 to 5.9 cm. in length, three are females with eggs 

 in an advanced stage of development; one, evidently a male, has 

 the mouth so filled with eggs that it is distorted and apparently 

 incapable of being closed. The black stomachs of nearly all are well 

 filled with food; one which was examined contained small crusta- 

 ceans.

Two long slender incurved canines at symphysis of each jaw; a 

 narrow band of cardiform teeth merging posteriorly into a row of 

 slender canines on lower jaw; a narrow band of cardiform teeth on 

 front of upper jaw, widening posteriorly, and an outer row of slightly 

 larger teeth; a single row of teeth on vomer and palatines; dorsal 

 vii-1,10; anal 11,8; scales large, ctenoid; gill-rakers long, about 3 + 8.
