from specimens from Uualaska. This species is taken abundantly in shal- 

 low water about Kadiak south of the Alaskan Peninsula, thence westward 

 through Unimak Pass, along the northern shore of Unalaska Island to the 

 Kuril Islands, and the Pribilof Islands and in Bristol Bay. The depths 

 range from 38 to 121 fathoms. (7tapddoqo$, unaccountable.)

This genus differs from rychrohih -H chictly in the long continuous dorsal 

 and anal, the former having L.M rays, the latter 11. Anterior rays of spi- 

 nous dorsal not bound down by skin of the body, the iirst apparent ray 

 being nearly above gill opening. Skull extremely soft and cavernous, the 

 long oblique lower jaw especially so. (Named for Dr. Charles Henry Gil- 

 bert, "who has contributed more than anyone else to our knowledge of 

 the fishes of the North Pacific.") 



The following is the original description of Psiichrolutes paradoxus, Giinther: 

 " Branchioategals 7 ; D.9; A. 9;G. 12; V.2. Head large, not quite so high as broad, ita 



length being = of the total. Tho snoutis obtuse, although considerably longer than the eye, 

 rounded, with the upper profile steeper than the lower. The cleft of the mouth is oblique, 

 of moderate width with the jaws equal anteriorly: a narrow hand of minute teeth in the 

 jaws; the palate appears to be smooth. The maxillary, which is widened at its posterior 

 extremity, extends to below the middle of tin- eye. The nostril is situated very near to 

 the extremity ot the snout, and provided with a very short tentacle. The eye is imme- 

 diately below the upper profile; its diameter is about j of the length of the head, of that 

 ot the snout, and nearly of the width of the interorbital space. The iufraorbital emits 

 a slender process across the cheek, which, however, does not reach to the preopercular 

 margin. None of the opercles are armed; the operculum alone is produced into a flexible 

 short posterior process : the gill opening commences above that process, and is not contin- 

 uous with that of the other side, the gill membranes being attached to the isthmus. The 

 branchiostegals are exceedingly slender, 7 in number. The body is subcvliudrical ante- 

 riorly and compressed posteriorly; its greatest depth, behind the head, is of the total 

 length ; the skin is perfectly smooth and rather loose. The pectoral is pointed, the upper 

 rays being the, longest and extending nearly to the dorsal; the ventrals rather short, close 

 together, situated below the middle of the base of the pectoral, and composed of 2 rays, 

 the inner of which is bifid. Dorsal and anal tins opposite each other, situated far back- 

 ward on the tail, terminating at some distance from the caudal, and nearly entirely en- 

 veloped in skin. Caudal slightly rounded, of moderate length. The vent is situated 

 about midway between the root of the ventral and the origin of the anal. The upper 

 parts are brownish gray, minutely dotted with black, and with 2 very large deep brown 

 blotches of irregular size. The caudal and pectoral fins are dotted and spotted with black.

" This fish resembles in its general habit somewhat the genius Liparis. Gulf of 

 Georgia (Vancouver Island), voyage of H. M. S. Plumper.'' 1 



Dr. Boulenger says, October 24, 1895: "I have examined the type of Psychrolutespara- 

 doxua. I count 12 soft rays, the anterior embedded in the thick skin, so that Dr. Giiuther's 

 statement is to be accounted for. But there are no spines." Later Dr. Boulenger writes 

 us that he has compared Dr. Gi'mther's type with the figure of Psychrolutes zebra, published 

 by Jordan &. Starks, and finds that it agrees fully with the latter. There is, therefore, 

 little doubt that the species zebra is identical with paradoxus.
