THE PISHES OF THE IXCOI.F EXPEDITIONS. 25 



for younger and for older specimens. In the very youngest specimens the extension of the scale- 

 covering is more limited -- on the belly to the region before the ventrals, while the belly proper is 

 entirely without scales. The shape of the snout is here the same as in other Macruri, not bowlike 

 rounded, but sharply triangular. The first dorsal fin begins immediately over the insertion of the 

 pectorals, which again is in the vertical from the first point of the ventrals. The first longest raws 

 of the ventrals are almost equal with those of the pectorals, but shorter than those of the first dorsal 

 fin. The number of rays is i -\- n in this fin, 19 in the pectorals, 8 in the ventrals. The teeth are 

 minute, almost hidden between the papillae of the mouth. 

 Of the other northern species

(figured in Voyage en Scandinavie , Poissons, pi. n, in Smitt's .Scandinavian fishes, pi. XXVII, A,

The largest specimen has a length of 28 inches, the smallest of 2"/ 1 6 inches. As to the geo- 

 graphical distribution, for which the above cited work of Collett mav be referred to, it may be 

 remarked, that beyond the shores of West-Greenland and Xorway (from Helgeland to Christianiai 

 and Bohuslan) this < Berglax is known from the sea between Shetland and the Faroe Islands and has 

 several times found its way to the most northern shores of Denmark. In Oceanic Ichthyology p. 403
