94r Rcmarlcs on Certain Species of 



one with very fine stride (anfr. 65), and in another (anfr. Y), 

 with the strise rather coarse, I have detected the internal 

 lamina. In both, the outer whorl is without the characteristic 

 features of II. Carjpenteriana. Among a considerable number 

 of specimens I found the lamina only in the two referred to. 

 I have never seen it in the Bermuda shell, of which I have 

 examined very many individuals. 



The Bermuda shell was known to Say. He wrote a descrip- 

 tion, wliich was, however, never published. The following is 

 a copy from the original MS. in the possession of Mr. Binney : 



" II. CHEiLODON. — Discoidal, labrum reflected — a tooth on the labium. 

 Inhabits Bermuda. 



" Shell discoidal, the spire very slightly convex, whorls nearly 6, with 

 elevated strias across, forming somewhat regular intervening grooves, — 

 body whorl angular above its middle, beneath which it is convex, and 

 only wrinkled, the grooves terminating at the angle or carina, — umbilicus 

 dilated, exhibiting the volutions to the apex : aperture rather longer 

 than wide, — labrum contracting the aperture a little, reflected, excepting 

 towards its superior termination, and declining a little at its junction 

 with the preceding volution : labium with a short, oblique tooth. 

 Breadth, | inch. The late Mr. Stephen Elliott presented to me this 

 shell, which he obtained from Bermuda. It is more completely fastigiate 

 than even H. septemvolva Nob., and there is no obvious calcareous 

 deposit on the labium, as in that species." 



It may be remarked that Say's description agrees almost 

 entirely with that of Deshayes of microdonta, — in specimens 

 from Bermuda, not completely full grown, but with reflected 

 lip, the labial tooth is of the character mentioned by Say. 



Helix fastigans L. W. Say. — In my Eemarks (Ann. Lye. 

 Yol. YI. p. 283) on H. faiigiata Say, I noticed that the name 

 was originally written by Say correctly, viz. fastigiata, and 

 that Pfeiffer had remarked to the effect that the former word 

 is unmeaning. Mrs. Say, anxious that this long-standing 

 typographical error should be removed, expresses her wish
