the orbit; teeth cardiform in both jaws; the lower teeth beset the outer 

 slope of the jaw. Ventral as long as head; pectoi'al If in head; dorsal 

 spine serrate, l^^^ in head. Apparently close to M, acrolepis, but probably 

 with shorter head, longer ventrals, and longer dorsal spine, the eye also 

 larger. Length 22 to 26 inches. Bering Sea. Only 2 specimens known.

Head about 4.}; depth at ventrals 7; eye 3A in head; snout 4; maxillary 

 2,f; mandible 2^; pectoral about 2; ventral about l^. D. XI-111 + ; A. 

 94 + ; P. 20. Form of i/. ?><Tj/i!a.r, width of head f its height; iuterorbital 

 width f eye; snout moderate, pointed. Origin of tirst dorsal from snout a 

 distance 3 times length of upper jaw; base of first dorsal 3i in head, or 

 about 3 times distance between dorsals; first dorsal spine very short, the 

 second about if in head, serrate in front. Distance of anal from snout 2k 

 times its length ; distance of pectoral from snout slightly greater than 

 head; distance of ventral origin from snout ^ its length. Length 2 feet 

 or more. Coasts of Vancouver Island, Washington and Oregon, in deep 

 water, in 345 to 786 fathoms; common. A small specimen taken by us oif 

 Bogoslof Island. Our specimens have 11 rays in the first dorsal, not 11,

Macrurus acrolepis, Bean, Proc. U. S. Nat, Mus. 1883, 362, Straits of Juan de Fuca, near 

 Neah Bay, Washington (Coll. Jauies G. Swan, from the .stomach of a fur seal) ; JoK-

Macrourus acrolepis, -Tohdan & Gilbert, Kept. Fur Seal Invest., 1898. 



2962. MACROURUS STELGIDOLEPIS, Gilbert. 



Head 4f ; depth 5i ; eye small, 31 to 4 in head; snout 4i. D. II, 10 or 11 ; 

 A. 130; scales 155; 5 or 6 scales between lateral line and base of first dor- 

 sal. Body deep, the lower profile rapidly rising along anterior portion of 

 base of anal, the tail thus abruptly becoming slender. Head short and 

 deep; snout heavy, little produced, acute at extreme tip; infraorbital 

 ridge not prominent on sides of head or snout, not continued backward on 

 preoperele. A pair of narrow, transverse naked strips on upper surface 

 of snout near tip, separated on each side by a single scale from the naked 



*The following is Gill & Townsend's description of Macrourus dorsalis : 

 "Dorsal 15-120; anal 122; pectoral 21; ventral 9. Scales deciduous and rather small, 

 diversiform, with small exposed surfaces; near the dorsal tliey have about 5 radiating 

 spinigerous ridges, but below tlie lateral line those ridges are fewer and unarmed ; snout 

 short, projecting a considerable length beyond the eye and a little beyond the supramax- 

 iUary; median tubercle very prominent; connecting ridge well defined ; infraorbital 

 nearly vertical, with tlie ridge linear and near the orbit; teeth cardiform." 



To this we add the following, from our examination of their type: Head 5f ; depth 7; 

 eye 43; snout 4; iuterorbital ■width slightly greater than eye; niaxilLiry 23; ventral fin J 

 pmger than head, 4^ in body; pectoral IJ in head. Dorsal spine strongly serrate, its 

 length equal to that of bead.
