MARINE MOLLUSKS — MACQINITIE 99 



men about 35 mm. long from 125 feet has a long, narrow canal, slightly 

 reflexed, but not arcuate, suggestmg a variety of B. cepulus. The 

 specimen of var. gunneri from 438 feet also has a long canal, but it is 

 arcuate and not so narrow as in the B. clathratus from 125 feet. In a 

 specimen of var. gunneri from 125 feet there are only 9 or 10 varices, 

 which extend outward markedly from the posterior end of the last 

 whorl. In other specimens of var. gunneri from Point Barrow the 

 varices number up to 15; there is great variation in the depth of the 

 varices (which is reflected in the degree of angulation at the shoulder), 

 in the length of the canal, and in the proportion of the length of the 

 spire to the length of the aperture and canal. 



Distribution: Bafiin Land to Cape Cod; Greenland; Iceland, the 

 Hebrides, England, the Faroes, Norway, Spitzbergen, Novaya Zemlya, 

 White Sea, Franz Joseph Land, the Siberian Arctic. Thorson (1944) 

 also lists Bering Strait, Alaska, Puget Sound, and Japan, but none of 

 our western literature mentions B. clathratus or even var. scalari- 

 formis. I believe that the Point Barrow specimens form the first 

 published record of B. clathratus from Alaska and the Pacific area 

 (although Gray's Fusus lamellosus (1839), which was from Icy Cape 

 is undoubtedly B. clathratus). However, I also believe that careful 

 study of specimens of B. beringi, and perhaps B. pacificus, in the 

 U. S. National Museum will reveal specimens of B. clathratus and var. 

 gunneri taken from south of Bering Strait.

Seventeen living and 7 dead specimens were collected : 3 living and 

 2 dead specimens washed ashore in September 1949; 1 dead specimen 

 came from 110 feet; the remainder were dredged from 11 stations from 

 120 (Aug. 8, 1949) to 741 feet, with 4 living coming from 175 feet. 

 The entire spire and part of the last whorl of a specimen from 162 feet 

 were covered with a species of Syncoryne. 



Other material examined: Numerous specimens from localities 

 from Icy Cape through Bering Strait to the Pribilofs, the Aleutians, 

 the Shumagins, Cook's Inlet, and 1 from Puget Sound (see below) ; 

 also from Kamchatka. 



Discussion : In the specimens from Point Barrow the varices varj- 

 from 17 to 25, the majority of the shells having from 19 to 21. This 

 species has a wider canal than B. clathratus, a more tumid body whorl, 

 and the varices do not project so far. Out of 1 17 specimens examined 

 in the collection of the U. S. National Museum, only 22 have 12 varices
