Head 4; depth 5i; D. VI-I, 24, 2; A. I, 16, 2; P. iii, 16; V. I, 5; 

 scales about 105 in a lateral series to base of caudal ; about 12 between 

 origin of dorsal and lateral line; width of head 2 in its length; depth 

 of head If; mandible 2^; third dorsal spine 5^; base of spinous dorsal 

 2|-; spine of soft dorsal 4f ; first undeveloped dorsal ray 2f ; anal spine 

 1\\ first anal ray 3-| ; least depth of caudal peduncle 5; pectoral 1^; 

 ventral 2; snout 2f, from its tip; eye 6; maxillary 3; interorbital 

 space 2^-^. 



Body elongate, fusiform, slender, and compressed, greatest depth 

 near origin of soft dorsal. Caudal peduncle small, compressed, and 

 its width If in its depth. Tail sloping down graduaUy. A small pit 

 at origin of each caudal lobe. 



Head elongate, subconic, compressed, pointed, and upper profile 

 almost straight from end of snout to occiput. Snout long, pointed, 

 rather broad, and with upper jaw projecting. Eye small, with narrow 

 eyelid, and midway in length of head. Mouth small, slightly curved, 

 and with mandible projecting beyond upper jaw. Maxillary broad 

 posteriorly till equal to f of eye, its entire edge slipping under preor- 

 bital, and reaching posteriorly half way between nostrils and front of 

 orbit. Lips thick and fleshy, especially lower. Teeth in fine rasp-like 

 bands in jaws, broader anteriorly, but not connected at symphysis or 

 front of upper jaw. Vomer and palatines with patches of fine teeth. 

 Tongue long, free, rather thin, upper surface with numerous small 

 velvety patches, and tip broadly rounded. Nostrils small, lateral, 

 together, and near last third of space between tip of snout and front of 

 eye. Interorbital space broad, and elevated. A broad median ridge 

 from snout to occiput, and also a broad ridge over each eye. Margin 

 of preopcrcle entire. 



Gill-opening extending forward till opposite nostrils. Rakers 9 + 26 , 

 compressed, long, with fine bristles on inner edges, and longest but little 

 shorter than longest filaments. Filaments a little shorter than eye, 

 and pscudobranchisD about half as long as latter. Branchiostegals
