MARINE MOLLUSKS — MACGINITIE 135 



hole in the ice, at 162 feet; 2 (14.4 by 6.6 and 15.1 by 6.3 mm.) at 

 175 feet; 1 (19.1 by 8.8 mm.) at 213 feet; and 1 (10.2 by 5 mm.) at 

 420 feet. In addition, a dead shell (17.3 by 8.7 mm.) was taken at 

 110 feet, and another (20,5 mm. long) at 213 feet. 



Other material examined: Several specimens in the collection of 

 the U. S. National Museum. 



Discussion: There is variation in the number of ribs, and in some 

 specimens there is a tendency toward a shoulder, though the latter is 

 more of an effect than an actuality. The description of this species 

 was published in 1885, not 1884 as given by Dall (1921, p. 75). 



Distribution: Point Barrow south and east to the Queen Charlotte 

 Islands, British Columbia. Dall (1921) says that it is circumboreal, 

 but Johnson (1934) does not list it and European authors do not 

 mention it. 



*'Oenopota" elegans (Moller, 1842) 



Plate 16, figures 7, 8 



Defrancia elegans Moller, 1842a, p. 13; 1842b, p. 86. 

 Bela elegans G. Sars, 1878, p. 225, pi. 16, fig. 15. 



Four specimens were dredged: 1 living (13.3 by 5 mm.) and 1 

 recently dead (10.8 by 4.3 mm.) at 152 feet; 1 drilled (12.6 by 4.6 mm.) 

 at 175 feet; and 1 living (12.2 by 4.9 mm.) at 204 feet. 



Discussion : Dr. Thorson compared these specimens with Moller's 

 type specimens from western Greenland, He says that the one from 

 204 feet (pi. 16, fig. 8) is a trifle broader than the types, but that the 

 others are quite typical (pi. 16, fig. 7). He adds that, after examining 

 specimens from Iceland, Greenland, and New England, he is inclined 

 to believe that G. Sars' figure (1878, fig. 15 on pi. 16) is of an extreme 

 variant of the species. 



Distribution: Point Barrow and Blizhni Islands to St. Lawrence 

 Island, Bering Sea; also (Thorson, 1944) Iceland, western Greenland, 

 Spitzbergen, and northern and southern Norway. Point Barrow is 

 a new locality.

A single living specimen (11.4 by 4.9 mm.) was dredged at 130 feet 

 on Aug. 9, 1949. This specimen is white, tinged with creamy buff 

 near some of the sutures and nodes. 



Distribution: Point Barrow to Puget Soimd; and (Thorson, 1944)
