In E. claviger, the fin rays are still more numerous, 5 specimens 

 from Bering Sea examined by us having the dorsal VIII-14, and the 

 anal with 11 or 12 rays. In both type and cotype of E. taurinus, 

 the dorsal rays are VII-9, the anal rays 7. 



The orbital region is compressed and high, strongly arched above 

 the occipital and the nasal regions. Interorbital space concave, the 

 occipital region more deeply so. Anterior profile nearly vertical. 

 Mouth small, the maxillary reaching vertical from front of pupil. 

 Eye large, its diameter about twice the interorbital width, equaling 

 the length of the snout. Nasal spines strong in the type, the nasal 

 bones sculptured. Preorbital with two strongly protruding spinous 

 processes in the young type, these little marked in the adult cotype. 

 Upper preopercular spine robust, reaching well beyond the opercular 

 margin; the usual three strong spines below it. Opercular ridge very 

 high, rough-granular. All exposed bones of head finely granular. 

 A single short filament at tip of maxillary, the cotype with a papilla 

 or undeveloped filament anteriorly at its base. Teeth fine, in broad 

 bands in the jaws, a narrow band on the vomer, the palatines naked. 

 A short slit behind the fourth gill-arch. Isthmus very wide, equaling 

 the distance separating the two pectoral fins. 



Plates of the lateral line higher than long, those anteriorly with a 

 sharp lengthwise crest, which becomes rounded in the posterior 

 scutes. The lateral line opens principally in a single minute pore 

 above each plate and a similar one below it, but occasionally more than 

 one such pore is present, especially in the anterior part of body. 

 The space between the lateral line and the base of the dorsal is covered 

 with fine prickles, more evident in the young than in adults. The 

 anus is but little in advance of the first anal ray, not reached by the 

 tips of the ventral fins. 



Upper parts olive or olive-brown, marbled or mottled with lighter, 

 and with scattered small blackish brown spots. Under parts light, 

 a white streak below middle of sides sending irregular incursions into 

 the darker area above, this more noticeable in the adult specimen. 

 A double dark bar below the soft dorsal, one encircling caudal pe- 

 duncle below, a dark blotch at base of lower caudal rays. Pectoral 

 with a dusky basal area which intensifies posteriorly to form a brown 

 bar on middle of fin; beyond that a broad white bar, the terminal 

 area of fin with a second narrow brown bar or with small brown spots. 

 In the cotype, the entire lower side of head is dusky. 



In addition to the type, a specimen 160 mm. long, here designated 

 a cotype, is in the collection of Stanford University, from Albatross 

 station 2893, in the Santa Barbara Channel, southern California, 

 depth 145 fathoms. The dorsal spines of this specimen have been 

 injured, but can be counted without possibility of error, and the other 

 fins are intact.
