from specimcus from Unalaska. This species is takeu abundantly in shal- 

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

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

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

 range from 38 to 121 fathoms. (7rapd5o|o5, unaccountable.)

This genus differs from I'sychrolutes chiefly in the long continuous dorsal 

 and anal, the former having 24 rays, the latter li. Anterior rays of spi- 

 nous dorsal not bound down by skin of the body, the first ai>parent ray 

 being nearly aliove gill ojiening. 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 extremity ot tlie snout, ami jirovided with a very short tentacle. The eye is imme- 

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

 of the snout, and nearly iof the width of the interorbital space. The infraorbital 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 iiroiluced into n flexible 

 short i)osterior process; the gill opening commences above tli.it iiroccss and is not contin- 

 uous with tliat of the other side, the gill membranes being tittarlKil w tlic istlimiis. The

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

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



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

 dcxii)!. 1 count l■^ soft rays, the anterior embedded in the thick skin, so that l)i-. ( i iinther'a 

 statement is to bo accounted for. But there are no spines." Later Dr. Boiili iii;cf w 1 iles 



us that he has <■ pared Dr. GLinther's type with the figure of P»yckrolutes .u-hj ,1 .~]\n\i]is]ifi 



byJordau iV Staiks, and finds that it a'grees fully with the latter. There is, therulore, 

 little doubt that the species zebra is identical with paraduxus.
