MARINE MOLLUSKS — MACGINITIE 115 



a live specimen, had one barnacle and a few cells of bryozoan colonies 

 growing on it. 



Other material examined: About 25 specimens from localities 

 ranging from Icy Cape (one dead shell from the beach) to the Pribilofs, 

 the Aleutians, and southeast of the Aleutians. 



Discussion: This species exhibits variations in the prominence of 

 the obliquely longitudinal ribs and in the character of the sculpturing. 

 Small specimens show spiral threads that are given a wavy effect by 

 the incremental lines. The spii-al threads vary in coarseness, and in 

 some shells they may be grouped; in the larger specimens the shells 

 are often too worn to show the sculpturing, but in some there are 

 several irregularly spaced spiral cords on the last whorl. 



Distribution: Point Barrow to around Unimak Island in the 

 Aleutians; also Spitzbergen. The only reference to a living shell 

 north of the Arctic Circle appears to be that of the type from Spitz- 

 bergen. The Point Barrow specimens represent a new localit}^ 

 record and the first living specimens from Arctic Alaska.

One dead and 5 living specimens were collected: the largest, the 

 dead shell (107 mm. in height by 53.8 mm. in diameter, and fore- 

 shortened by breakage at both ends), was taken at 125 feet; 1 (12.7 

 mm. in height) at 162 feet; 2 (44.7 mm. and 48.4 mm.) at 453 feet; 

 and 2 (60.4 mm. and 64.6 mm.) at 522 feet. One of the shells had 

 been broken and repaired several times. Although even the living 

 shells are worn and encrusted, fine spiral lines are visible. 



Other material examined: Nine specimens labeled B. malleatus 

 and a few B. stimpsoni from localities ranging from Point Barrow (1 

 beach specimen) to the Pribilofs. 



Discussion: "Wlien Gould wrote the original description of B. 

 stimpsoni, he did not figure the species. Later Dall (1925) selected a 

 specimen to represent the type, and his figure of it (pi. 7, fig. 2) is 

 the same figure as appears in Oldroyd (1927, pt. 1, pi. 21, fig. 2). 

 Unfortunately, in the text of his paper Dall confused^^the museum
