smooth ; dorsal fins widely separated. Pectorals short, placed high, oppo- 

 site upper angle of gill cleft. Scales small, bristly. Origin of lateral line 

 at upper angle of gill cleft. (/taXanos, soft; HsQahr?, head.) 



2944. MALACOCEPHALTJS OCCIDENTALS, Goode & Bean. 



Eye 2 in head; barbel slightly longer than eye; snout 4 in head; inter- 

 orbital space 4. Agreeing with Giinthers description of M. Icvvis, but 

 differing in the position of the vent, the ventrals, and the anal tin, the last 

 commencing at a distance behind the vent equal to length of snout; dis- 

 tance of vent from origin of veutrals less than its distance from origin of 

 anal ; ventrals originate under middle of first dorsal ; origin of pectorals 

 under that of first dorsal, the pectorals as long as head without postorbital 

 flap ; ventrals reaching to or slightly beyond origin of anal. Gill rakers 

 rudimentary, x-\-\\. Second dorsal spine nearly equal to length of head; 

 first branched dorsal ray about as long as head. Atlantic Ocean, off 

 Cape Hatteras, and Caribbean Sea. Length 8 inches ; a doubtful species, 

 perhaps identical with M. Icevis. (occidentalis, western.) 



Malacocephaluf occidentalis, GOODE & BEAN, Proc. U. S. Nat. Mus. 1885, 597, off Cape Hat-

Moseleya, GOODE & BEAN, Oceanic Ichthyology, 417, 1896 (longiftlis). 



This genus is near Nematonurus, having the mouth small, the upper 

 teeth in 1 or 2 series, the dorsal spine weakly serrate, and the dorsal fins 

 well separated. The chief difference lies in the scales, which are feebly 

 ridged and nearly or quite smooth. The typical species, M. longifilis (Giin- 

 ther), is from off the coast of Japan. (" Named in honor of Prof. Henry 

 N. Moseley, F. R. S., of Oxford University, whose contributions to natural 

 history while naturalist of H. M. S. Challenger we desire to commem- 

 orate.") 



2945. MOSELEYA CYCLOLEPIS (Gilbert). 



Dorsal II-8 or 9; ventral 12: eye 4| in head; snout 3|; maxillary 2f. 

 Head smooth, compressed, without conspicuous ridges; median and lat- 

 eral rostral ridges terminating in slightly projecting points, the median 

 process, a short portion of the median ridge, and the edge of the membrane 

 connecting median with lateral processes, with spiuous scales and points. 

 Snout projecting beyond the premaxillaries for f its length. Eye small, 

 less than snout, very slightly exceeding interorbital space; mouth small, 

 wholly inferior, maxillary reaching vertical from posterior margin of 

 pupil. Premaxillary teeth in 2 series, the outer similar to those in mandi- 

 ble, not enlarged or canine-like, the inner series smaller, directed obliquely 

 backward; a single series of teeth in mandible, not widening into a patch 

 at syrnphysis. Barbel thick at base, length of snout. Preopercle 

 incurved above the angle, the lower limb expanded, the marginal region 

 striate. First dorsal inserted behind axil of pectoral (second spine broken 

 in both specimens examined), the basal portion smooth, a single sharp
