iug from lateral liue quite lo the aual fiu, aud behind the anal completely 

 encircle the caudal peduncle. In TrvjJops pingeli, the space along the anal 

 and the lower sides of caudal peduncle is naked. Dorsal fins not con- 

 nected, the membrane from last dorsal spine connecting with extreme base 

 of first soft ray; spinous dorsal higher than soft dorsal, the dorsal spines 

 contained 2^ times in length of head; rays and spines slender; base of 

 anal ec^ual in length to that of second dorsal, a little more than J length 

 of body; caudal truncate, with a number of short auxiliary rays above 

 and below, and 12 fully developed rays, each of which is twice bifurcate; 

 pectorals reaching beyond front of anal, the longest ray 1^- to If in length 

 of head, the lower rays enlarged and exserted, forming a distinct lobe, 

 some of the rays of which are longer than the upper part of the fin ; veu- 

 trals reaching beyond vent, very narrow at bas(% inserted close together, 

 the outer ray not provided with the broad membranaceous flap present in 

 TrUjlops pingeli. Color olivaceous above, light yellow with more or less 

 silvery on sides of head aud belly; traces of 4 saddle-shaped bands of 

 darker color reaching across back aud below lateral liue; 1 under first 

 dorsal, 2 under second dorsal, and 1 on back of caudal peduncle; more or 

 less of the outer portion of gill membranes black, edged posteriorly with 

 white; gill cavity black and roof of mouth dusky; dorsal and caudal fins 

 indistinctly blotched with black, the blotch on the dorsal corr^esponding 

 more or less closely to the bars on the back ; a large black blotch on upper 

 part of pectoral aud on side of body just above axil; peritoneum silvery 

 grayish. Very closely related to Triglops hcani and Triglops pingeli, but 

 diflering in the following respects: The eye is much larger, the snout 

 shorter, and the maxillary shorter and broader. The maxillary bone and 

 the lower half of cheek are invested with prickles, not naked. The lower 

 thickened portion of the pectoral fin is produced to form a lobe. The 

 scales on the upper half of the body are much coarser. The dorsal series of 

 enlarged prickles much less conspicuous. The lateral folds are much more 

 numerous, averaging about 4 to 1 pore of the lateral line, reaching to or 

 nearly to the anal fin and encircling the caudal peduncle below. The ven- 

 tral fins are nmch narrower and nearer together. The lateral line has a 

 much more pronounced upward curve over the base of the pectorals. A 

 short, high occipital ridge is present, but does not terminate in a distinct 

 spine. (Occipital ridge obsolete in heani, a bare trace of it sometimes 

 visible). Aleutian Islands; several specimens, from 68 to 155 mm. in length, 

 taken from south of Sannak and north of Uualaska Island, in43 to 138 fath- 

 oms. (Gilbert.) {dHeTttixoi;, thoughtful, reflective, in reference to the 

 appearance given by the large eyes.) 



Triglops scepticus, Gilbert, Kept. U. S. Fish. Com. 1893 (1896), 428, pi. 28, fig. 2, Aleutian 

 Islands, at Albatross Stations 3215, 3222, and others, in 43 to 138 fathoms. 



721. STERNIAS, Jordan & Evermann, new genus. 



Slernias, Jordan & Evermann, new genus (xcnosUthus) . 



This genus is closely related to Triglops, differing chiefly in the scaly 

 breast, which is not crossed by folds or mucous chauuels. Back aud head 

 coarsely scaled. Pacific, (drepvov, breast.)
