The Conchologist is the title of a new periodical published at 

 Leeds, England. It is issued quarterly and is devoted for the 

 greater part to the mollusks of Great Britian. The second number, 

 just issued, contains the following articles : Note on the locality of 

 Helix mandarina Gray, by E. A. Smith ; The glacial Period and 

 British non-marine mollusca, H. E. Quilter ; The Laud and Fresh- 

 water mollusca of Oxfordshire, W. E. Collinge ; Adventitious Pro- 

 tection in Fresh-water mollusca, C. Clare Fryer; On the Burrowing 

 Habits of Testacella, C. D. Horsmaii. The Conchologist is edited 

 by Mr. W. E. Collinge, of Leeds, England. We wish it success. 



On some new * * West American shells, etc., by Wm. 

 H. Dall. (Proc. U. S. Nat. :Mus. 1891, p. 173-191 ; three plates.) 

 The dredgings of the Albatross, as well as a number of West Coast 

 collectors, ^Slr. J. J. Rivers, Miss Ida M. Shepard, Mrs. M. Burton 

 Williamson and others, have contributed the shells described and 

 illustrated in'this paper. The species of Eupleiira, both East and 

 West, are first discussed and figured. Nassa californiana Conr., 

 originally described as a Miocene fossil under the generic name of 

 Schizopyga by Conrad, has been found living from Drake's Bay to 

 Cerros Island, 25-65 fras. Fusus Kobelti Dall^ F. Harfordi Stearns, 

 Trophon triangulatus Cpr. and dementia subdiajihana Cpr. are fig- 

 ured for the first time. Trophon Cerrosensis, Cancellaria Crawfordi- 

 ana and Tellina Idee, spp. nov., are figured and described. The 

 paper concludes with brief descriptions of the following : Benccinum 

 strigillatum, taphrixim, molinia frielei, stromhella middetidorffi, fragi- 

 lis, melonis, chrysodomusithiiis, periscelidus, phcenicens, eucosmius, 

 hypolismus, acrosnius, halibrectus, Trophon scitulus, disparilis, punc- 

 trella {galeatea var. f) major, solenya johnsoni, calyptogena paeifica 

 (new genus and species of carditidce), Limopsis vaginatus. All are 

 West Coast forms, mostly from Alaska. We hope that illustrations
