60 THE NAUTILUS. 



U. S. Nat. Mus., vol. 49, pages 33-62, with plates 28-33). 

 An interesting introduction giving a history of the work done 

 in this genus, with a key to the species, followed by the descrip- 

 tions of 38 species of which 22 represent new species. R. signce 

 is proposed for R. insignis De Folin, 1867, not R. insignis Adams 

 and Reeve 1850. Only one of the number is fossil. The figures 

 are excellent. 



Etude sue le Littorina obtusata et ses variations. Par. 

 Ph. Dautzenberg et H. Fischer. (Journ. de Conch., vol. 62, 

 pages 87-128, plates 2-4). A most interesting study of the 

 variations of this species. A complete bibliography is followed 

 by notes and descriptions of the varieties or form, which are 

 grouped under the typical obtusata and the sub-species littoralis. 

 The former is divided on form into typica, elatior and palliata 

 and 9 vars. on color, and the latter into 5 vars. on form and 12 

 on color. Only palliata is recorded from the mainland of N. 

 America. L. littoralis is recorded from Greenland. That L. 

 palliata was only a var, of obtusata has long been the opinion 

 of the writer, from the large series before me, representing 18 

 localities, cover the area from Eastport, Me., to Narragansett, 

 Pier, R. I. A large percentage have the obtuse shoulder on the 

 body whorl and cannot be separated from European specimens 

 of littoralis. The color vars. typica^ lutea, castanea, balteata, 

 ornata lineolata and tessellata are also represented.

NOTES. 



Lymnaea (Pseudosuccinea) columella Say in Oregon : Mr. 

 John A. Allen has found this species in Oswego Lake and Duck 

 Pond, Oswego, Clackamas Co., Oregon. They were collected 

 during April and May, 1913 and in February 1914. This is 

 new to the west coast, I believe, and probabl}^ was introduced 

 from the eastern United States. E. G. Vanatta. 



Dr. H. A. Pilsbry left on August 4th for New Mexico (via 

 San Francisco). He expects to return about the end of Sep- 

 tember.
