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 has a ver\- great resemblance to L. pallidus^ and I tliink it most prudent 

 meantime to consider it a variet\- of this species. In time it ma\' possibly be raised to a separate 

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



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

 of 537 — 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. i e 

 on Tab. IV) forms in part a transition stage to the variety sqiiamiventer ^ being scaled on the upper- 

 most part of the belly (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.

The typical L. pallidus is found in the Kara Sea, at Spitsbergen, 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 11 specimens at a depth of 46— 106 fathoms. 



At S p i t z b e r g e n the Norw. North-Atlantic Expedition took 2 specimens where the depths were 

 260—459 fathoms, and the bottom-temperature -j- i°i and — i' C; a Russian Expedition i sjjecimen in 

 Stor Fjord at a depth of 60 fathoms, and bottom-temperature of — 2°C.; the Kolthoff Exj^edition of 



1900 I specimen at the mouth of Ise Fjord, where the depth was 185 fathoms, and the IMichael Sars - 



1901 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' W.L. where the depth was yj fathoms (i specimen). The Kolthoff Expedition of 1900 obtained 

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

 Josephs Fjord, outer part of Myskoxe Ba\', 106 fathoms (i 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'/2 — 18 fathoms (35 specimens, i of 178 mm., i of 125 mm., 

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

 (74" 30' N.L. 18° 40' W.L.), 42 — 53 fathoms (i 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 — 0^5 and o°6 C. 



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

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



Off th e Shetland-Norw ay Slope (62° 43' N.L. 1' 26' E.L.) the ]\Iichael Sars» in 1902 

 took 6 .specimens, where the depth was ca. 420 fathoms and bottom-temperature under 0° C. 



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

 Jan Ma5-en (St. 116) where the depth was 371 fathoms and bottom-temperature — o'4 C.
