48 THE NAUTILUS. 



of Attorney-General Jackson, written in answer to a query addressed 

 to the tax commission by G. Frank Tuthill, supervisor of the town 

 of Southold, inquiring whether oyster beds should be assessed as real 

 or personal property and to what purpose the taxes derived there- 

 from are to be devoted. The courts have held, says Mr. Jackson, 

 that oysters are wild animals and become personal property when 

 they are reclaimed or artificially planted. Such domesticated, tame 

 or ' garden ' oysters would be assessable as personal property under 

 the ordinary rules." — {Boston Globe.') 



Students of the Unionidas may be interested to know that on

 culata (Barnes) gravid. All four branchiae were charged with ova. 

 More details will be communicated later. — V. Sterki. 



PUBLICATIONS RECEIVED. 



A Preliminary Catalogue of the Land and Fresh-water 

 Mollusca of Ohio. By V. Sterki (Proc. Ohio State Acad, of 

 Science, iv, part 8). This very valuable addition to our State cata- 

 logues gives an epitome of Dr. Sterki's work in Ohio in the past 

 twenty years, with such other species as have been reported on good 

 authority from the State. The total number, 310 species, is prob- 

 ably exceeded by no Northern State. Attention is called to species 

 which should specially be looked for in Ohio, such as Gastrodonta 

 gularis, Omphalina laevigata, etc. A separate list is given of species 

 from pleistocene deposits. Dr. Sterki's notes on the various species 

 will be read with interest by those engaged in similar studies, his 

 intimate acquaintance with inland mollusks giving weight to the 

 view r s expressed. 



A New Parasitic Mollusk of the Genus Eulima. By 

 Paul Bartsch (Proc. U. S. Nat. Mus., 1907). E. ptilocrinicola lives 

 parasitic on Ptilocrinus pinnatus Clark, dredged by the steamer 

 Albatross off British Columbia in 158S fms. The proboscis is deeply 

 inserted in the side of the body of the crinoid. This is like Stylifer, 

 yet the apex is not mucronate as in that genus, and there is an oper- 

 culum. The largest specimen is 9.5 mm. long.
