ASTARTE ARCTICA Gray, 1824. 



Bering Strait, Bering Sea, and the Aleutian Islands from Attn to 

 Unalga Pass east of Unalaska in 15 to 60 fathoms; also in the eastern 

 arctic waters. 



See the eastern list for synonymy and further data. 



ASTARTE BOREALIS Schumacher, 1817. 



Polar Sea, near Bennett Island; Jeannette expedition. Macfarlane 

 Bay, near the mouth of the Mackenzie; Bering Strait and southward 

 on the American side to Port Etches, Prince William Sound, and on 

 the Asiatic side to Yokohama. 



For synonymy, etc., consult the eastern list. The variety rliom- 

 holdalis Leche, 1883, as figured, is based on an immature specimen, 

 while the variety placenta Morch is simply the young shell of the 

 normal type. A somewhat elongated specimen figured under the 

 name of A. scotica by Middendorfi', Plate XVI, figs. 10-12, 1849, may 

 be the young of this species or an unusually strongl}- ribbed eUijptica. 

 He gives localities from Lapland to the Okhotsk Sea. The latter 

 were probaljl}^ horealls; the former might have been dliptica. His 

 figures on Plate XVII of the same name are probably A. sulcata. 

 Figs. 6 to 7 on the same plate under the name of corrugata Brown are 

 probably ^1. borcaUs; figs. 4, 5, 8, 9, and 10, perhaps, are dilapidated 

 A. rollandi. In the Sibirische Reise, Plate XX, figs. 1 to 4, 1851, 

 which are named A. scotica., represent A. horealis^ and it is evident 

 he regarded the two as S3''nonymovis. A. compressa., on the other hand, 

 he does not record from eastward of the Taimyr River. The Macfar- 

 lane Bay specimens are exceptionally smooth, compressed, and thin. 



ASTARTE ALASKENSIS Dall, 1903. 



Southern part of Bering Sea, the vicinity of the Shumagin Islands, 

 and eastward along the Alaskan coast and south to Puget Sound in 10 

 to TO fathoms. Also in the glacial drift of Sucia Island, Straits of 

 Georgia. 



Much resembling .1. elllptlca of the eastern coast, but shorter, 

 heavier, and more trigonal. The periostracum is black or dark brown 

 and dehiscent when dry. It has usually been identified as undata but 

 is never crenulated. 



ASTARTE COMPACTA Carpenter, 1865. 



Puget Sound, Kenncrley, and Johnson. 



Small, stout, trigonal, like A. esijuimalti., but with regularly arcuate, 

 uniform concentric ri])l)ing. It was described as a variety of A. com- 

 jyressa Montagu, which does not occur on the coast. It appears to be 

 rare, and I have seen only one specimen beside the type. The former 

 is figured, Plate LXIII, fig. 8.
