452 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
Dorsal beginning over end of opercular flap, its distance from nape equaling distance 
of latter from posterior margin of pupil. Membrane of last spine slightly joined to 
base of caudal. Anterior dorsal spines short, but well connected by membrane. 
Anal with three distinct spines, shorter than the rays that follow, the second the 
longest, all as strong as dorsal spine, and fully connected by membrane. Rays all 
branched at tip. Membrane of last ray joined only slightly to base of caudal. 
Caudal sharply pointed in our specimens, the median rays longest, about as long as 
head. Pectorals evenly rounded, the median rays longest, 14 or 15 in number, all 
branched. Ventrals well developed, about two-fifths as long as head, consisting of 
one short, sharp spine and three rays, the spine not closely joined to rays. 
Lateral line indistinct, usually appearing obsolete, more evident toward head, con- 
sisting of a series of distinct pores along median line. Scales very small, cycloid, 
imbricated, covering body, including abdomen, breast, and nape. Cheeks scaled, the 
head otherwise naked, or sometimes with a small patch of scales on upper part of 
opercles. D. Lvi11 to Lx; A. m1, 40 to 42. 
Color: Sides with a series of 10 to 12 narrow white crossbars, the first in front of 
dorsal fin, the last under last dorsal spine, the bars about one-fifth interspaces. 
Above lateral line they are conspicuously margined with darker; below lateral line 
they broaden out and become forked, forming A-shaped markings. Upper caudal 
rays at base with an oval white ring inclosing a darker area; this mark more 
conspicuous in the young. Belly and ventrals white, other fins dusky, but without — 
definite markings. 
Family CRYPTACANTHODIDA. 
122. Delolepis virgatus Bean. 
A decayed specimen was found on the beach at Unalaska. 
LYCONECTES gen. nov. (CRYPTACANTHODID£.) 
Differing from Oryptacanthodes principally in the absence of palatine teeth, agreeing 
with it in general appearance and in most details of structure. Mouth subvertical; 
lower jaw projecting; premaxillary protractile. Teeth strong, conic, wide-set, in — 
more than one series. Mucous pits prominent on head. Gill-opening narrow, ceasing ~ 
opposite middle of base of pectorals, the membranes widely joined to isthmus. 
Dorsal and anal wholly joined to caudal, the latter extending well beyond them. — 
Dorsal fin composed of spines only. No ventralfins. Body naked. No lateral line, 
Type L. aleutensis. 
123. Lyconectes aleutensis sp. nov. (Plate 34.) ji 
Head 74 in length, without caudal; depth 144. Dorsal Lxrx; anal 49; pectoral 13; — 
caudal 18. Head square in cross section, the upper and lower surfaces plain, the 
cheeks vertical, the depth and width equal. Mouth still more oblique than in 
Cryptacanthodes maculatus, with much heavier mandible and less expanded maxillary, — 
the exposed portion of the latter with vertical axis, not extending beyond vertical — 
from middle of the eye. Teeth all similar, few in number; those in premaxillary — 
arranged in two series, the inner of which aresmaller than outer, from which they 
are separated by a wide interspace. Teeth in mandible in asingle series laterally, 
becoming a sparsely filled patch toward symphysis. Four or five similar conical 
teeth on head of vomer. Palatines toothless. A long nostril tube overhangs the 
upper lip. Upper lip separated by a fold from forehead, the upper jaw protractile. — 
Eye extremely small, sunken in the socket, which it does not nearly fill, its diameter — 
slightly less than half interorbital width. The supraorbital rim is not elevated, and | 
contains no conspicuous projections. Suborbital rim swollen, with an enlarged - 
mucous channel; a conspicuous series of mucous pits along each mandible and the 
margin of the preopercle; two series on top of head, diverging backward from above
