132 • THE NAUTILUS. 



species of a decided Polynesian aspect are reported from the Gulf of 

 California region ; among these are Chicoretis palmarosce mexicana, 

 Ranella cruentata, Purpura hippocastanum, Casmarla vlbex and 

 Luponia Isabella mexieana. This paper includes also revised de- 

 scriptions of species previously described by the author, notably, 

 Dolabella californica, Onchiclella bivueyi= 0. carpenteri Stearns not 

 Binney, etc. A new species of Teetarius, T. atyphus, the first of this 

 group detected on the West Coast is described ; it occurs at Manta 

 on the coast of Ecuador. Other species are referred to and com- 

 mented upon. 



The last of the foregoing titles relates to a paper hitherto briefly 

 noticed in "The Nautilus, " (December, 1893). This includes a 

 list of Galapagos shells, compiled from the collections made by the 

 Albatross, Dr. Habel, Dr. Wolf, the Petrel, Dr. W. H. Jones and 

 the papers and publications of Carpenter, Albers, E. A. Smith, 

 Wimraer, Ancey, Reibisch, Dall, etc., etc. The Albatross collectors 

 obtained 109 species and several varieties; of these 59 were not 

 before reported as occurring at the Galapagos. A few new species 

 were detected and are described by the author. The total as yhown 

 in the summarized list is 288 species and 30 varieties. 



The land shells are of a distinctly West American type, compar- 

 able with Chilean and Peruvian forms, and with the exception of 

 half a dozen local species, the marine forms are West American — 

 with a slight color of Caribbean or Autillean types. 



Notes on Recent Collections of N. A. Mollusks, etc., by 

 E. E. C. Stearns (Proc. U. S. Nat. Mus. 1893). Dr. Stearns records 

 numerous new localities for various land and fresh-water shells, dis- 

 cussing particularly the range of Patula strigosa Hemphilli, and its 

 occurrence in Arizona at Coon Mountain, that problematic crater. 

 Triodopjsis Levettei is reported from Fort Huachuca and Tucson 

 Arizona (a large form). Ft. Huachuca is so near the Mexican 

 boundary that Stearns believes both P. heinphUli and 2\ Levettei 

 will eventually be found in the Mexican state Sonorai Helicina 

 orbicul'ita was collected by Mr. V. Bailey near Marble Cave, Stone 

 Co., Mo., probably near its northern limit. Attention is called to 

 the discontinuous distribution of the section Mesodon, which is repre- 

 sented by several western species, among them townsendiana and 

 ptyclwphora ; records of North Dakota and eastern Montana locali- 

 ties for Mesodon are still lacking. In this tract vndtilineata and 

 thyroides are to be expected, we think, but suitable stations are not 

 very numerous west of Minnesota and Iowa.
