The heiijlit over the anus (in incdin 111- sized and ad nit indi vidnals) is 5,2 — 5,9" „ 

 (if the total len<;th. The head is tolerably broad, the trnnk a little compressed, the 

 tail gradually becoming more strongl\- comj^ressed and losing slowly in height. The 

 length of the head in males is 14,1 — 15 " ,,, in females 13,7 — 14,2 °'„') of the total 

 length. The lower jaw reaches almost to the end of the upper. 7 pits for the lateral 

 line along the upper jaw and under the eye. The distance between the snout and 

 the anus is in males 27,2 — 28,6 " „, in females 26,2 — 27,7° „ of the total length''). 

 The distance of the dorsal fin from the snout is 21 — 24,7° o of the total length. 

 Small specimens uniform^' gray-brown along the back, yellow- white on the under- 

 side, somewhat larger specimens similar but with irregular, brown to black cross- 

 markings and shades over the back and tail, and with a dark stripe between the eye 

 and the snout; older individuals uniformly yellowish brown with indistinct shadings 

 down the sides. The scales in developed specimens reach to the head and partly 

 out on to the unpaired fins. The lateral line ventral, indistinct. Pyloric appendages 

 rudimentary. The size up to 184 m m.

Prof. Collet t has recently (1898) given so detailed and careful information concerning this 

 species, a relatively considerable number of specimens of which has been brought to light by the 

 practical fisheries investigations of Dr. Petersen and Dr. Hjort, that there is no need to treat of it 

 anew. As supplementar\- information I shall only state the proportions of the 8 specimens from the 

 Skager Rak at w\\ disposal, mentioning the se.x; it will thus appear that the differences in propor- 

 tions are not great in adult individuals (cf. Diagnosis). 



'1 In small specimens (44—62 mm. long) 14,9 — 17,500, according to Collett.

i) Concerning the separate locaHties where the species was taken, cf. Collett 1. c. 1S9S and C G. Joh. Petersen, 

 Beretning IX fra den biologiske Station, p. 17, 21 & 22 (Fiskeri-Beretning for Finansaaret 189S— 99, Kjobenhavn 1900). — How- 

 far the fonn from North .-Vtlantic, in 180 fatlioms^, which Giinther formerly referred to Anguilla kiencri, and Day cor- 

 rected to Lycodes kieneri and Giinther finally to L. sarsii |cf. Voy. Challenger. Rep. Deep-Sea Fishes, XXII, 1887, p. So), 

 is reaUy a L. sarsii, I shall leave nnanswered as I have not seen the specimen; if the accompanying figure in Chall. Rep. 

 I Fig- 3 1 purports to be more than a sketch, it would indicate indeed that the form was not identical with L. sarsii.
