from the late Mr. Bednall's collection, the material now being 
E the hands of Mr. Iredale, and reported upon by him as 
above. 
When in Philadelphia last year Dr. Henry A. Pilsbry 
showed me some of the material that Mr. Bednall had sent 
him (at the time the description of S. pilsbryanus was written) 
as being the new shell. I easily identified in the material 
shown to me the three species S. juloides, Ad. and Ang.; 
S. eymodocealis, Ashby; and S. posidonialis, Ashby ; all very 
small and juvenile. 
It is therefore fairly evident that Mr. Bednall's drawings 
ere made from more than one specimen 
all the material. I therefore propose to refer the speci 
am describing hereunder to Mr. Bednall’s species for the 
following reasons : — 
(1) I am anxious to retain the names of my friend 
Dr. Pilsbry and my late friend Mr. Bednall as 
associated with the interesting genus of Stenochiton. 
(2) It is desirable to keep our list of species free from 
those that are impossible of identification. 
(3) The form I am describing corresponds most closely 
with the figure of the shell in Mr. Bednall's paper. 
(4) Mr. Bednall’s shell was practically from the same 
locality, “Troubridge Shoal, St. Vincent Gulf, on 
." Tapley Shoal is about 6 miles from
