Depth of body 2^ times in total length excluding caudal, length of 

 head 5J times. Diameter of eyes 8 times in length of head, equal to 

 interocular width ; length of mouth 3J times in length of head. 

 Upper eye in advance of lower ; snout projecting beyond lower jaw, 

 mouth extending to posterior border of lower eye ; snout, lips, and 

 borders of gill-cleft with a strong fringe ; a fringed dermal flap 

 covering nostril on blind side. 



Dorsal with 73 rays, anal with 55 ; longest f length of head. 

 Caudal obtusely acuminate. Eight and left pectoral fins about equal 

 in length, measuring T 3 ^ length of head. Scales strongly ctenoid on 

 coloured (right) side, cycloid on left ; lateral line straight, extending 

 over 105 scales. 



Colour (of preserved specimen), right side dark brown, pectoral fin 

 black, dorsal and anal fins with a white edge, caudal mottled light

PARALICHTHODES ALGOENSIS, Gilch. 



Teeth, small, in 3 series on each jaw. Depth of body 2J times in 

 total length excluding caudal, length of head 4J times. Longitudinal 

 diameter of eye greater than vertical and a little more than twice the 

 interocular space ; lower jaw projects beyond upper by about half 

 the vertical diameter of the eye ; maxillary of left side more exposed 

 than that of right, the latter extends backwards to below the middle 

 of the lower eye. 



Dorsal 70 ; originates on snout midway between its anterior 

 extremity and the eye, not joined to caudal ; 1st ray inserted slightly 

 to left of median line, is entirely separated from the 2nd and is 

 divided into 6 branches ; 2nd and 3rd rays are joined at the base by 

 a membrane and are also to the left of the median line ; the 4th and 

 subsequent rays are in the median line and the branchings of the 

 rays gradually become fewer till above base of pectorals they are 

 simple, becoming again divided in posterior fifth of fin ; longest ray 

 2^ times in length of head. Eight pectoral fin longer than left and 

 H times in length of head. Eight ventral situated on median line 

 and nearer head than left, which it about equals in length, the 

 distance between origin of anterior rays of each equals J the vertical 

 diameter of the eye. Anal 50 ; about equal in height to dorsal and
