for what he calls Parmarion. If we admit that the Javan slugs are 

 ii' i <,'ir<i*i<i nor Ibyciix, then they are assuredly not P'/rmnrinti : for 

 that genus was founded by Fischer on four slugs, one of which is a 

 Mm-liielln one a Giiwiu (Indian), one an Ibycus (Indian), and the 

 other a Jfynlhim.r .' 



In conclusion, we may cordially echo the author's wish that fur- 

 ther Bornean material may he obtained by them, for they have cer- 

 tainly only obtained a glimpse of the undoubtedly rich slug-fauna 

 of that region. T. D. A. COCKEBELL. 



REVIEW OF OUK PRESENT KNOWLEDGE <K THE MOLLUSCAN 

 FAUNA OF MICHIGAN, by Bryant Walker (address delivered before 

 the Michigan Acad. Science, Dec. 27, 1*1)4). Michigan has a long 

 Malacological history, for a Western State, beginning with Dr. 

 SAGER, in 1839, who had worthy followers in MILES, CURRIER and 

 Di;( 'AMP, successive historiographers of the rich mollusk-fauna of 

 that great State. Other Michigan naturalists McNEiL, STRENG, 

 LATHROP et al. 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 nattualists. 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.
