60 THE NAUTILUS. 



Vanatta's investigation places the generic position of the species on 

 an indisputable basis. H. A. PILSBRY. 



A LARGE PEARL. A short time ago, one of the students of the 

 Southern Collegiate Institute, of Albion, 111., had occasion to use a 

 live Unio in illustrating some point in zoology. When the shell 

 was opened there was found in the mantle quite a large, regularly- 

 formed pearl, 12 mm. wide, and 7 mm. high. The pearl was found 

 in the anterior side of left valve. There is quite a depression in the 

 valve where the pearl was found, although it was not connected with 

 the shell. The Unio from which the pearl was taken is U. multi- 

 plicatus Lea, and is a mature shell. It was found in the Bonpas 

 Creek, not far from where it empties in the Big Wabash River. C.

MR. SLOMON Rons, whose stock of Cape shells is well known to 

 many of our conchologists, has removed to 929 DeKalb Ave., 

 Brooklyn, N. Y. He reports the receipt of large consignments of 

 South African shells, including most of the recently described species. 



NEW PUBLICATIONS RECEIVED. 



CHECK LIST OF NORTH AMERICAN NAIADES, by B. H. Wright 

 and Bryant Walker. Svo, pp. 19, Detroit, 1902. An alphabeti- 

 cally arranged list of species with the genera and groups indicated, 

 and the distribution briefly stated. It will prove useful for checking 

 collections, as well as for determining the modern genera of collec- 

 tions labeled by Lea's system. It is based upon Simpson's 

 Synopsis. 



NECROLOGY. 



A veteran conchologist, WILLIAM LEGRAND, of Tasmania, has 

 just died, aged 82. He was a book-seller in Hobart, and printed 

 (with his own hands) a little book, Collections for a Monograph of 

 Tasmanian Land Shells (1871), which Tryon noticed in Volume III. 

 of the Manual of Conchology. Much of the Tasmanian material 

 described by Hanley was, I believe, obtained by him, and Tenison- 

 Woods described many shells from his collection. Tate and May 

 named a genus Legrandina after him. Turris legrandi Ten.-Wood ; 

 Columbella legrandi T.-W.; Calliostoma legrandi T.-W.; Gibbula 

 legrandi Petterd ; Zidora legrandi Tate, perpetuate his memory. 

 His collection was purchased by C. E. Beddome. C. HEDLEY, 

 Sydney, N. S. Wales, July 9, 1902. 



We regret to record the death of DR. J.G. COOPER, at Haywards, 

 California, on July 19, at the age of 72 years. Extended notice 

 will follow.
