regarded as new: Turbonilla pentalopha, auricoma, latifundia, lowei 

 and variety pedroana, arnoldi, and adleri; Odostomia steamsii, die- 

 gensis, and grammatospira. 



In 1904, the present authors prepared and published in the Pro- 

 ceedings of the Biological Society of Washington a Synopsis of the 

 Genera, Subgenera, and Sections of the Family Pyramidellidse. This 

 hardly admits of condensation, but contains numerous new divi- 

 sional names and the descriptions of the following new species serving 

 as types of groups named in the table: Pyramidella (Sulcorinella) 

 dodona, Turbonilla (Baldra) archeri, Odostomia ( Vilia) pilshryi, and 

 Odostomia (Evalina) americana, of which, however, only the last- 

 mentioned is a native of the Pacific coast. 



In 1906, through the kind intervention of the late Prof. Eduard 

 von Martens, in charge of the conchological collection of the Berlin 

 Zoological Museum, w*e received for study their entire series of Pyra- 

 midellida?, including numerous author's types derived from many 

 sources, of which the most important were from the collections of 

 the late Henry and Arthur Adams, of Paetel, of Dunker, of Clessin 

 and of Hilgendorf. Numerous species inadequately described by 

 Arthur Adams were included, and were for the first time figured and 

 placed on a valid basis in the report on this collection.^ Among the 

 species discussed or described from the west coast of America in this 

 report were the following: Odostomia (Evalea) siikaensis Clessin, 0. 

 {Amaura) martensin. n., 0. (A.) Jcrausei Clessm, 0. {Heida) panamensis 

 Clessin; Pyramidella (Longchxus) hicolor Menke, P. (Pharcidella) 

 hastata A. Adams, and P. (P.) moffati, n. n.
