LIPARIS GIBBA, Bean. 



No. 38974, TJ.S.N.M. Petropaulski, September, 1883; 2^. Grebnitski. 

 Length of specimen, ^\ inches. D. 40; A. 30. 



The widtli of the mouth over the extremity of the maxiihiries slightly 

 exceeds the length of the eye and snout combined, and is considerably 

 more than one-half length of head. The eye is one-half as long as the 

 snout, equaling one-vsixth length of head, and uearly one-half inter- 

 orbital space. The maxilla extends almost to the vertical through the 

 front margin of the eye. The teeth are in very broad bands in the 

 jaws; blunt conical. 



The depth of the gill opening is contained 2^ times in length of head; 

 the distance between the lower ends of the gill oi)ening equals the 

 length of the head without the snout. The front margin of the ven- 

 tral disk is almost directly beneath the hind margin of the eye. The 

 width of the disk equals its length, which is uearly equal to the post- 

 orbital length of the head. Thirteen papillne form an outer circle 

 around nine smaller papilla", which are in the center of the disk. Each 

 of the papillie of the outer row has a brown spot in the center, except 

 the anterior one which has two of these spots. The lower portion of the 

 pectoral is procurreut on each side, the two portions separated at their 

 origin by a very narrow interspace only about half the length of eye. 

 The pectoral, when extended, reaches almost to the origin of the anal; 

 it is very large, the width of its base equaling the length of the head 

 without snout. The longest pectoral ray is about three-fourths as long 

 as the head. The distance of the dorsal origin from the tip of the snout 

 is contained ^\ times in the total length without caudal. The greatest 

 depth of the body, at the pectorals, is almost equal to the length of 

 the head and slightly exceeds one-fourth of the total length without 

 caudal. The caudal is connate with the dorsal and anal; its length 

 equals that of the head without the snout, and slightly more than one- 

 sixth of the standard body length. 



The color in spirits is grayish, much mottled with large, pale areas. 

 The same peculiarities of marking are found on the pectorals. The 

 iish may have been purplish in life. It was taken from a depth of 18 

 fathoms.
