 1429. HYPOHOMIS S(JIAMATUS (Gilbert & Swain). 



Head 3f ; depth 5A. D. XIV-13 ; A. II, 10 ; scales 10-82-18. Body elon- 

 gate, the sides and caudal peduncle compressed ; back elevated, the pro- 

 file forming a slight angle at occiput; head very long and slender, with 

 a long acuminate snout, as in Hadropierus pltoxocephalus, which this spe- 

 cies somewhat resembles in appearance. Cleft of mouth long and narrow, 

 the lower jaw included in closed mouth; maxillary reaching vertical 

 from front of orbit, its length equaling that of snout, 3i times in head; 

 upper jaw not protractile. Bands of teeth very wide, the outer premaxil- 

 lary series enlarged. Vomerine patch well developed. Eye moderate, I5 

 in snout, 4f in head to end of opercular spine, 2^ times the furrowed inter- 

 orbital width. Preopercular margin strictly entire. Gill membranes 

 Avidely united across isthmus. Spinous dorsal long and low, spines from 

 the third to the tenth subequal in length, those anteriorly and posteriorly 

 gradually shortened ; longest spine i length of head ; spinous and soft 

 dorsals well separated ; base of soft dorsal equaling \ the distance from 

 its origin to front of spinous dorsal; anal shorter than soft dorsal, but 

 higher and inserted more anteriorly ; anal spines strong, the first slightly 

 the longer, about equaling length of snout ; highest anal ray nearly half 

 length of head; caudal emarginate, the lobes rounded, 1;' in head; pec- 

 torals equal to length of head behind front of eye ; ventrals l.| in head. 

 Body covered with very small scales, uniform in size, and completely invest- 

 ing the ventral region, which is without series of enlarged scutes ; cheeks, 

 breast, and nuchal region covered with still finer scales having entire 

 edges, and the opercle with larger spinous scales ; interopercle and part 

 of subopercle naked; an enlarged black humeral scale. Colors in life: 

 Yellowish olive, with about 10 broad dusky bars across the back, and an 

 equal number of dusky blotches along lateral line ; a conspicuous black 

 humeral spot ; a broad black line forward from eye to snout, and a nar- 

 rower line backward from eye to upper preopercular margin ; opercle and 

 occiput largely dusky ; a diffuse dusky blotch at base of tail, with a small 

 round, jet-black spot behind it ; spinous dorsal translucent, with a broad 

 subterminal brownish-orange band; soft dorsal and caudal barred with 

 dusky and orange-yellow; pectorals slightly reddish; ventrals translucent. 

 Length 5 inches. Ui^per Tennessee River Basin ; known from the Watauga 

 and French Broad rivers ; rare ; a large and interesting species, remarka- 

 ble for its long and slender head ; perhaps the type of a distinct genus. 

 {squamaius, scaly, the scales being small and close-set.)
