for what he calls Parmarion. If we admit that the Javan slugs are 
not Girasia nor Ibycus, then they are assuredly not Parmarion ; for 
that genus was founded by Fischer on four slugs, one of which is a 
Mariaella one a Girasia (Indian), one an Jbycus (Indian), and the 
other a Hyalimax ! 
In conclusion, we may cordially echo the author’s wish that fur- 
ther Bornean material may be obtained by them, for they have cer- 
tainly only obtained a glimpse ef the undoubtedly rich slug-fauna 
of that region.—T. D. A. CocKERELL. 
REVIEW OF OUR PRESENT KNOWLEDGE OF THE MOLLUSCAN 
FAUNA OF MICHIGAN, by Bryant Walker (address delivered before 
the Michigan Acad. Science, Dec. 27, 1894). Michigan has a long 
Malacological history, for a Western State, beginning with Dr. 
SaGeEr, in 1839, who had worthy followers in MrLEs, CURRIER and 
DeCamp, successive historiographers of the rich mollusk-fauna of 
that great State. Other Michigan naturalists—McNEIL, STRENG, 
Larurop et a/.—have made large additions to our knowledge of the 
mollusca, not to mention the Eastern authors Conrad, Anthony, Lea, 
Tryon and others, who described material collected by the ardent 
and enthusiastic band of Michigan naturalists. All of this is most 
interestingly related by Mr. WALKER, in this survey of the history 
of Michigan Malacology. In the notes accompanying his tabular 
enumeration of all species reported from the State, from all sources, 
(284 entries), much valuable information is given, but so condensed 
that no useful abstract is possible. A full bibliography of Michigan 
conchology concludes the paper.—H. A. P. 
A CATALOGUE OF THE Marine Mouiusks oF JAPAN has been 
issued by Messrs. Frederick Stearns and Henry A. Pilsbry. It is 
a handsome volume of 204 pp., and 11 plates. Suitable notice of — 
the contents will be given next mouth.
