116 NEW FISHES FROM PACIFIC COAST GILBERT. 



ing about six backward directed spines, and from two to four pairs 

 of lateral ridges also bearing spines, the lateral ridges sometimes ex- 

 tending the whole width of scales, sometimes confined to their basal 

 portion; marginal spines longest. Axil of pectorals naked, its base 

 anteriorly with small cycloid scales. 



A naked, much depressed, elliptical area between bases of veutrals 

 in all specimens. 



Second dorsal spine smooth, weak, little exceeding length of soft 

 rays, equaling length of snout and orbit. Base of first dorsal L} in 

 interspace between dorsals, which is 2| in head. Distance from front 

 Of anal to snout equals one-third total length. Ventrals with the outer 

 ray produced, about reaching frontof anal. Pectorals reaching beyond 

 anal, half length of head. Ventrals with seven rays. Pectorals with 

 fifteen to seventeen rays. 



Color: Light olive-brown, dusted with coarse black specks ; axil of 

 pectorals, belly, ventrals, and branchiostegal membranes blue-black; 

 lower side of head dusky. Mouth anteriorly, including tongue and half 

 of palate, white; its posterior part and most of lining of gill cavity jet- 

 black ; inner lining of cheeks abruptly white. Lower part of iris sil 

 very. Peritoneum silvery, with coarse dusky specks. Vertical fins 

 dusky, the anterior portion of anal black. 



Many specimens, the longest 12 inches long, from Station 3015, in 

 145 fathoms. 



82. Macrurus (Macrurus) stelgidolepis sp. uov. 



Head 4f in length; depth oi. D. II, 10 or 11; A. 130. Lat. 1. ca. 

 155 ; five or six scales between lateral line and base of first dorsal. 



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 backwards on 

 preopercle. 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 nostril fossa. A double series of scales intervenes between the 

 nostrils and the orbit. Lower side of snout wholly naked anteriorly, 

 partly scaled laterally. 



Mouth large, overhung by premaxillaries for a distance about oie 

 half diameter of orbit. Premaxillaries in advance of nostrils; maxil- 

 laries reaching vertical from posterior margin of pupil, 2| in head ; 

 snout about equaling interorbital width, 4.^ ; eye small, 3i to 4. Barbel 

 long, five-sixths orbit. 



Teeth in cardiform bands of equal width in both jaws, narrowed l:Jt- 

 terally, but not to a single series. Anterior series in upper jaw enlarged^ 

 in lower jaw all the teeth of equal size, 



Preopercle broadly rounded, the angle but moderately produced, a 

 narrow strip of the interopercle visible for its entire length. Outer
