 length of the hodi/ or than !)() % of the hase of the second dorsal fin, the last measuring from HO to H3 % of the 

 length of the hodg. Length of the loirer Jaw le.'is than Id % of that of the body. Base of the pectoral fins 

 rertical and fairly straight, the length of these fins measured from the upper corner of their insertion being about 



21 % of the length of the body, or slightly less than when measured from the lower corner, in n-hich case it is 



22 %: the lower and thicker rays free for a relatively great part of their length. Head superiorly and laterally, 

 and the back aborc the lateral line, in adult specimens, covered irifli a verrucose skin, which is firmly united to 

 the subjacent bones, and shagreened on the head. The breast (the ventral side in front of flic ventral fi'ns) with 

 the skin gathered into fnnisverse folds, like those belonging to the sides of the body below the lateral line, but the ven- 

 tral side from flic ventral fins to the vent smooth. Anterior part of the lateral line curved downwards. Colo- 

 ration essentially the same as that of the preceding species, but the dark spots on the sides are blacker in full- 



groivn specimens, and the belly is purer ivhife and even lustrous.

" In a specimen 37';.i mm. in length the length of the head = 27'2 % of that of the body; in two specimens 154 mm. in length 



'' In old specimens about 36 % of the longitudinal diameter of the eye, in young 39 %. 



' In old specimens the latter is as much as 2'1 K of the length of the body, in young as much as 3-4 f, or even 4'2 % 

 vouth this species thus corresponds, in this respect, to the older stages of the three preceding species. 

 '' Sometimes 7, according to Kroyer and Lutken. 

 "^ Sometimes 12 or 13, according to Krover, LCtken and Collett. 



•'' Sometimes 26, according to Collett. In a specimen from the Cattegat there are only 20 rays in the second dorsal fin. 

 9 17 — 19, according to LOtke.S'; 17 — 21. according to Collett. 

 * 45 — 49, according to Collett.
