elevated. Eye very small, its length e(iual to one-fifth the width of 

 interoibital space, and less than one third tlie length of the snout. 



The anyle of tlie mouth is about under the middle of the eye; the 

 width of the mouth at the angle equals the length of the head without 

 the snout. The greatest width of the head is equal to its length, which 

 is three-elevenths of the total to caudal base. Teeth in many rows in 

 the jaws, sometimes blunt, but nearly all sharp pointed; no apparent 

 tricuspid teeth. 



The disk is placed very little behind the vertical through the hind 

 margin of the eye. Its width and length are nearly equal, the latter 

 equal to width of interorbital space and contained 8=^ times in the total 

 length to caudal base. 



The distance of the dorsal from the snout is one-third of the total 

 length to caudal base. The longest dorsal ray is one-half as long as 

 the head. 



The distance of the vent from the disk is a little more than one-fourth 

 the length of the head, the A'ent being almost under the origin of the 

 dorsal. The anal origin is under the eleventh dorsal ray. 



The pectoral reaches l>eyond the vent; its length equals that of 

 the postocular i)art of head. 



The caudal is one-half as long as head, and is not continuous with 

 the dorsal and anal. 



This does not agree with the descriptions of L. tunicata and L.fabricii 

 in color and in the continuity of the vertical fins, but in other respects 

 the agreement appears to be perfect. L. arctica, Gill, which this species 

 resembles in color, has the vertical fins confiuent, the interorbital space 

 one-third length of head, the caudual one seventh of total length, and 

 the anterior nostrils simple and posterior tubular.
