NOTE ON A CALIFORNIAN HELIX. 

 BY HENRY A. PILSBRY. 



In the " Manual of American Land Shells " Mr. Binuey figured 

 a shell from San Pablo as a form of " Arionta calif orniensis var. 

 ramentosa Old." It would seem that the same form has been sub- 

 sequently described by both Dall and myself, although until recently 

 collating materials for the new catalogue of U. S. land shells, I had 

 entirely forgotten that I had ever noticed the form in question. 

 The published references are as follows: 

 1885. " A smaller form of this variety \_i. e. ramentosa] from San 



Pablo," W. G. Binney, Man. Arner. L. Sh., Bull. 28 U.S. Nat. 



Mus., p. 133, f. 108 (no description). 

 1895, Feb. 2. Epiphragmophora californiensisv. contracostce Pilsbry, 



Guide to the Study of Helices, Man. Conch. (2), IX, p. 199 (a 



nude name). 



1895, Oct. 1. Epiphraf/mophora calif or niensis var. contracostce Pils- 

 bry, Nautilus IX, p. 72 (description). 



1896, Apr. 23. Epiphragmophora Arnheimi Dall, Proc. U. S. Nat. 

 Nat. Mus. XVIII, p. 6 (no description ; refers to Binney's 

 figures). 



1897, Jan. Epiphragmophora Arnheimi Dall, Proc. U. S. N. M. 

 XIX, p. 375 (full description). 



As will be seen from the above, the form was recognized by my- 

 self in 1894 when reviewing the Helices for the "Guide" but the 

 number in which the name appears although printed in 1894, was 

 not issued until February, 1895, and it was in no way defined at 

 that time ; the brief diagnosis then prepared being overlooked for 

 some months, finally appearing in October, 1895. I do not know 

 when the form was first recognized by my friend in Washington, 

 but from the notorious tardiness of the Proceedings of the Nat. Mus., 

 and the fact that a partial abstract 01 DalPs article appeared in 

 NAUTILUS for Sept., 1895, and was furnished by him a month or two
