THE NAUTILUS. 
last whorl widest, the latter hardly contracted below ; moderately 
solid, closely, lightly striated, the striae wanting on the earlier 
whorls, more distinct and spaced on the latter part of the last 
whorl. Color opaque purplish-brown. Whorls 12-13, but slightly 
convex, separated by a shallow, simple suture. Aperture contained 
4? to 4§ times in length of shell ; peristome reflexed, whitish, 
slightly thickened, not adnate; superior lamella strong, extending 
to the lip-edge; inferior lamella deep-seated, parallel to the superior, 
invisible from the front; subeolumellar lamella extending to lip- 
edge, bounded by grooves; palatal plicce two, the upper one long, 
second rather short, with a thin white subvertical callus below it, 
which is strengthened below into a low bar. 
Alt. 31, greatest diameter of last whorl above aperture 5 mill. 
Alt. 26, greatest diameter of last whorl above aperture 5 mill. 
Yaeyama (Okinawa), Loo Choo Is. (Fr. Stearns). 
Believing this species to be new, I sent examples to Prof. Dr. O. 
Boettger, the great authority on these shells, and received the fol¬ 
lowing emphatic confirmation of my opinion: “Die Clausilia von 
Okinawa ist ohne jeden Zweifel n. sp. Es ist eine StereojjJicedusa 
und steht in der Mitte zwischen japonica Crosse und brevior v. 
Mts.” 
No similar form has hitherto been reported from the Liu Kiu 
group, the nearest allies of the species being Japanese. It is named 
in honor of my friend Frederick Stearns of Detroit, who has 
contributed so largely to our knowledge of the Japanese fauna. 
The specimens vary considerable in length, but not in other char¬ 
acters. 
GENERAL NOTES. 
Mr. Wm. B. Marshall, who has been doing good work in the 
department of Zoology of the New York State Museum (Albany), 
has accepted the chair of Biology in Lafayette College, Easton, 
Penn a. 
The peculiar shell described in the June Nautilus as Perostylus, 
proves to be the larval form of Fusus proboseidiferus. A paper on 
the subject will appear in the September number.
