and unpaired fins; the colour is uniform and shows no indication of bands or spots (though it must be 

 remembered, however, that the young are unknown). 



For the rest, it lias a very great resemblance to L. pallidus , and I think it most prudent 

 meantime to consider it a variety of this species. In time it may possibly be raised to a separate 

 species, and its name squantiventer could then be retained as the specific name. 



As the facts are at present, I regard it as a deep water form of L. pallidus. It lives at depths 

 of S37- 957 fathoms, whilst the true L. pallidus in my opinion is not known to go to greater depths 

 than 495 fathoms. It seems to me worthy of remark in this regard, that one of the specimens of L. 

 pallidus from the deepest place (the 183 mm. long specimen described before and represented in fig. 1 e 

 on Tab. 1Y) forms in part a transition stage to the variety squamiventer , being scaled on the upper- 

 most part of the bellv (6 rows of scales beneath the descending branch of the lateral line) and contrary 

 to the usual, has scales on the base of the unpaired fins. 



Distributio n. 



The typical L. pallidus is found in the Kara Sea, at Spitz ber gen, at north-eastern 

 Greenland, and north from Iceland, north from the Faeroes and N.N.E. from Shetland. 



In the Kara Sea the Dijmphna Expedition took n specimens at a depth of 46— 106 fathoms. 



At Spitzbergeu the Norw. North-Atlantic Expedition took 2 specimens where the depths were 

 260—459 fathoms, and the bottom-temperature -(- i°i and - i c C; a Russian Expedition 1 specimen in 

 Stor Fjord at a depth of 60 fathoms, and bottom-temperature of -- 2°C; the Kolthoff Expedition of 

 1900 1 specimen at the mouth of Ise Fjord, where the depth was 185 fathoms, and the Michael Sars 

 E901 2 specimens at Ise Fjord at a depth of 140 fathoms. 



At north-eastern Greenland no fewer than 53 specimens have been taken. The Nathorst 

 Expedition of 1899 took it in Franz Josephs Fjord, at 400 fathoms (4 specimens) and at 73° 20' N.L. 

 21 20' WX. where the depth was 37 fathoms (1 specimen). The Kolthoff Expedition of 1900 obtained 

 it at the following places: Franz Josephs Fjord, head of Myskoxe Bay, 53 fathoms (2 specimens); Franz 

 Josephs Fjord, outer part of Myskoxe Bay, 106 fathoms (1 specimen); mouth of Franz Josephs Fjord, 

 106 -212 fathoms (4 specimens); off Franz Josephs Fjord, between Bontekoe Island and Mackenzie Bay, 

 132 fathoms (2 specimens); Mackenzie Bay, 6 1 2 — 18 fathoms (35 specimens, 1 of 178 mm., 1 of 125 mm., 

 the rest between 40 — no mm.); off Mackenzie Bay, 53 fathoms (3 specimens); S.E. from Walrus Island 

 174 30' NX. t8 40' W.L.), 42—53 fathoms (1 specimen). 



The Ingolf Expedition of 1896 took 7 specimens north of Iceland at St. 124 and 126, where 

 the depths were 293—495 fathoms, and bottom-temperature — o : 5 and o°6 C. 



The same Expedition of 1896 took 4 specimens north from the Faeroes at St. 138, at a 

 depth of 471 fathoms, and bottom-temperature — o°6 C. 



Off the Shetland-Norway Slope (62 43' N.L. i c 26' EX.) the Michael Sars- in 1902 

 took 6 specimens, where the depth was ca. 420 fathoms and bottom-temperature under o° C. 



The variety siuiilis was taken by the Ingolf Expedition of 1896 (15 specimens) south from 

 Jan May en (St. 116) where the depth was 371 fathoms and bottom-temperature — o°4 C.
