THE NAUTILUS. 



required much grubbing up of tufts of tall grass and shaking 

 out their roots, like digging up miniature potatoes. These are 

 the Annularia putris (Gundl. ) Pfr. and the Chondropoma margi- 

 nalbum Gundl. ) Pfr., the latter apparently quite rare. There 

 are no minute things beyond some few Ihysanophora inaguensis 

 Weinland. 



Some days we spent gathering marines on the little pebbly 

 beaches hidden far down under the lofty cliffs that mark this 

 rugged shore line, and we obtained some unusual species washed 

 up from the exceedingly narrow island- shelf ; blue water is but 

 a few hundred yards out. Among these are some Convs cedo- 

 nulli Lam. Beach collecting is, however, an aggravation; and 

 too much of it becomes a misdemeanor in the collector's ethical 

 code, for it obliges an acceptance of something short of the best. 



AMNICOLIDJE FEOM ONEIDA LAKE, N. Y. 



BY HENRY A. PILSBRY. 



The New York College of Forestry, under the direction of 

 Professor Hugh P. Baker, is carrying on a biological survey of 

 Oneida Lake and has issued an interesting bulletin 1 upon the 

 relations of mollusks to fish, by Frank C. Baker. Some Am- 

 nicolidse obtained during this work, and subsequent to the pre- 

 paration of the bulletin were submitted to the writer. The col- 

 lection proves to be of considerable interest, including some 

 species not before noticed. 



Amnicola bakeriana, n. sp. 



The shell is umbilicate, turrited-conic, thin, whitish -corneous, 

 somewhat translucent, with unevenly developed striation, dis-
