Lycenchelys Gill. 

 Lycenchelys Gill, Proc. Acad. Nat Sci. Philad., 1884, p. 180 (murcena). 



The body is very elongated (anguilliform), the height over the anus going ca. 

 16—24 times in the total length. Teeth on the intermaxillary and mandible, vomer 

 ami palatines. Lower jaw without barbules. Scales small. Lateral line ventral or 

 mediolateral, or both ventral and mediola teral. Branchiostegal rays 6. 



From the waters of North America 3 species of this genus have been described, namely: 

 Lycenchelys verril/ii Goode & Bean, off the east coast of the United States (34 39' 40" — 42° 33' N.L. 

 68° 22'— 75^ 14' 40" W.L.), 75 — 603 fathoms; Lycenchelys paxillas Goode & Bean, off the east coast of the 

 United States (35 45' 31'"— 42" 48' NX. 63 07' — 74°48'W.L.), 263—904 fathoms; Lycenchelys porifer Gil- 

 bert, off Lower California, 857 fathoms 1 ). 



From the European and Greenland waters are at present known 4 species, distinguished from 

 one another in the following manner: 



I. 7 pits for the lateral line along the upper jaw and under the eye. 



A. Distance of the dorsal fin from the snout is less than 20% of the total length. 



a. Length of the head is less than 14% of the total length. Colour uniform. (The cold 

 area off west Norway, east Iceland, and in the Fseroe Channel; 340 — 620 fathoms). 



L. murcena Coll.; p. 82. 



b. Length of the head is more than 14 % of the total length. Dark spotted colouration. 

 (Northern East Greenland; ca. 160 fathoms). L. kolthoffi Jensen; p. 88. 



B. Distance of the dorsal fin from the snout is 21 % or more of the total length. (Skager 

 Rak, south and west Norway; 70 — 300 fathoms). Z. sarsii Coll.; p. 86. 



II. 8 (larger) pits for the lateral line along the upper jaw and under the eye. (Davis Straits; 393 fathoms).
