behind wiiicli the others are arranged partly in two rows. Most of these 

 teeth, especially the inner and larger ones and the anterior canines, are 

 fieely depressible. A long series of teeth on the palatines, one or two 

 of the anterior teeth on each side and one or two others long, slender, 

 and fang-like. Tongue free anteriorly, roughish, but ai)parently with- 

 out teeth. Scales very large, cycloid. Dorsal fin inserted somewhat 

 behind the middle of the bodj", at a distance of nearly 4 times its base 

 in front of the anal, its height a little greater than the length of its 

 base. D. 11 ; A. 25. Anal fin anteriorly nearly as high as the dorsal, 

 its posterior rays low. Pectoral fins placed low, rather short, about as 

 long as the maxillary. Caudal fin short, narrow, apparently forked. 

 Yentrals (lost in the type) probably in front of the dorsal. Coloration 

 light olive, the sides silvery, with dark punctulations. Peritoneum 

 silvery, underlaid by black pigment. Santa Barbara Channel, California.

 caudal peduncle verj- slender; abdomen compressed. Head long; 

 snout sharp, half length of head. Eye large, high. Jaws equal; max- 

 illary reaching vertical from nostril; tip of lower jaw fitting into au 

 emargination of premaxillaries. None of the teeth fting-like; premax-
