120 THE NAUTILUS. 
PUBLICATIONS RECEIVED. 
A BrotoeicaL EXAMINATION OF LAKE Mrcuraavy, ete. (Bull. 
Mich, Fish Comm., No. 6). A brief resumé of the malacological 
results in the vicinity of Charlevoix, Mich., by Mr. Bryant Walker, 
is given on pp. 96-99. 
Tur Mouiusks AND BRACHIOPODS OF THE BAHAMA EXPEDI- 
TION OF THE STATE University oF Iowa (Nat. Hist. Bull. 8. U. 
I., 1V, No.1). By W.H. Dall. New forms are Murex nuttingi, 
Cerion niteloides, Liotia centrifuga, Carditella smithii, the latter from 
Bermuda. Cerion mumiola Pfr. is recorded from Tortugas, “ prob- 
ably the result of transportation by sea drift. If living at Tortugas 
it would add a new species to the fauna of the U.S.” The new 
species are figured. 
On THE CorRRECT PosITION OF THE APERTURE IN PLANORBIS, 
by F. C. Baker (Cincinnati Soc. N. H., XIX, p. 45). By the 
examination of young specimens and broken adults, Baker concludes 
that all the larger species examined are sinistral, the small ones 
dextral ; these terms being used in their old senses. The late work 
of Fischer and others on cognate inquiries is not referred to. 
Tur ANATOMY OF SPHHRIUM suLCATUM Lam., by Gilman A. 
Drew (Proce. Iowa Acad. Sci., 1895). A thorough and useful paper, 
illustrated by plates of details and a reconstructed figure from sec- 
tions. No useful abstract can be made; it may be mentioned, how- 
ever, that a vestige of the byssal gland persists in the adult. The 
typhlosole is not strongly developed. Sphzerium is hermaphroditie; 
but the ova and sperm are produced by distinct follicles, the ova- 
bearing being fewer and among the most posterior. A useful but 
not exhaustive bibliography is given. 
CONTRIBUTIONS TOWARD A LIST OF PAPERS RELATING TO THE 
NON-MARINE MonuuscA oF THE HAwAtiANn IsLanps, by E. R. 
Sykes (privately printed). Includes scattered papers, other than 
general or monographic works, and within this scope seems to be a 
nearly or quite complete bibliography. In a footnote on p. 5 Mr. 
Sykes calls attention to an error in a date given in the Proceedings 
of the Academy of Natural Sciences of Philadelphia, but in so doing 
commits an equal error himself, misquoting the date actually given 
in the Proceedings.—H. A. P.
