The late Edward R. Mayo of Boston left no will, but his chil- 

 dren have generously donated his valuable conchological collection 

 to the Boston Society of Natural History. — E. W. R. 



Collection for Sale. — We learn that the Collection of Dr. 

 Hartman is for sale, together with his Conchological Library and 

 other works on Natural History. Tlie Collection embraces about 

 8000 species of Marine, Terrestrial and fresh-water shells of the best 

 quality, many of which are rare and difficult to obtain. All parts 

 of the world are represented in this Collection, which has taken a 

 period of forty years to accumulate. They are all correctly named 

 and many are mounted. Inquiries should be addressed to Dr. W. D. 

 Hartman, West Chester, Penna. 



PUBLICATIONS RECEIVED. 



Mollusca of Santa Barbara Co., Cal., etc., by Dr. Lorenzo 

 G. Yates. A useful contribution to our knowledge of the distribu- 

 tion of West Coast shells, is this extensive local catalogue. We note 

 a number of errors in nomenclature, such as the retention of the 

 name " sanguinetis " for the common Leptothyra, etc., but such defects 

 do not really diminish the usefulness of the list. The following are 

 described and figured as new : Venus Fordii Yates, Vertagus Lordi 

 Yates, Vermiculuis Fewkesi Yates. 



Beaks of Unionid.e * =!^ of Albany, N. Y., by Wm. B. Mar- 

 shall (Bull. N. Y. State Mus. II, p. 170). A careful and well 

 illustrated study of the undulations of the beaks in Uniouidse, with 

 especial reference to the distinguishing marks of the various species. 

 This excellent Avork should be studied by all interested in Unionidie, 

 and extended by observers in various parts of the country. AVe 

 have elsewhere expressed the opinion that excellent group characters, 

 as well as specific characters are furnished by the beaks. — H. P.
