iransliratum that suffered no less than three major injuries. The 

 shell, which seems slightly heavier than the average var. transliratum, 

 is a much-worn specimen in which the cords are lacking. B. cnis- 

 matopleurum is not a vahd varietal name, much less a subspecific one. 

 Distribution: B. angulosum: Bernard Harbor and Point Barrow 

 to Kotzebue Sound; also Spitzbergen. Var. subcostntum: Point 

 Barrow to Icy Cape. Var. transliratum: Point Barrow south to 

 Bristol Bay and Unimak Island in the Aleutians. Var. normale: 

 Bernard Harbor and Point Barrow south to Kotzebue Sound; also 

 eastern Greenland and Spitzbergen.

Buccinum fringillum Dall, 1877, p. 4.' — Martini and Chemnitz, 1883, ed. 2, vol. 3, 

 abt. Ic, p. 88, pi. 91, fig. 9.— Oldroyd, 1927, pt. 1, p. 256. 



Two live specimens were taken on Oct. 11, 1949, at a depth of 453 

 feet. Including the 2 whorls of the nucleus, the larger of the 2 speci- 

 mens has 7 whorls, the smaller 6.5. Both are covered with perio- 

 stracum (heavier and coarser in the larger specimen) that projects 

 from the surface in heavily fringed axial folds. The larger shell is 

 37.7 mm. high by 24.6 mm. in diameter; the smaller, 28 by 20.5 mm. 

 Small barnacles, small colonies of bryozoans, and foraminifers were 

 growing on the periostracum. 



Other material examined : The type and 7 other specimens from 

 the north end of Nunivak Island. 



Discussion : B. fringillum is more closely allied to B. ciliatum than 

 any of the other species of Buccinum from Point Barrow, but the shell 

 is thinner and much more inflated, the periostracum is markedly 

 more fringed, and the sculpture is finer than that of B. ciliatum. (The 

 type locality is the north end of Nunivak Island in Bering Sea, not 

 "Arctic Ocean near Icy Cape," as given by Oldroyd.) 



Distribution: Point Barrow, and the north end of Nunivak Island 

 at 54 feet. The Point Barrow specimens represent an extension of 

 distribution in depth and a northerly extension in range from about 

 the 60th to the 71st parallel of latitude. 



•Dall (1921, p. 101) gives the following reference for Buccinum fringillum Dall, 1877: Proc. Calif. Acad. 

 Sci.. vol. 7, p. 9. Vol. 7, pt. 1, ser. 1, of the offlcial proceedings of the Academy, covering the meetings of 

 1876, was published In 1877. Buccinum fringillum is not mentioned in pt. 1 of vol. 7 and there is no pt. 2, 

 for the Academy did not begin publishing the second series of the Proceedings until 1888. Thus a period of 

 11 years elapsed during which no official proceedings were published. It is probable that Dall expected hii 

 paper to be published by the Academy, for the separate that was published followed the format of the Pro- 

 ceedings. The page number is more dlfBcult to explain, for the separate (see "References") containing the 

 description is paged from 1 to 8, and B. fringillum is described on p. 4.
