CONSHOLOGICAL SECTION of the Acadein7 of Natural Sciences of Philadelphia 



Vol. VI. 1870-71. Part 3. 



Meeting July Itli, 1870. 

 Mr. Tryon, Vice-Director, in the chair. 



The Chairman called attention to the curious error committed 

 by several conchologists in placing Strehelia{Physella) Berendtii 

 among the fluviatile mollusks. He supposed that the resem- 

 blance of the original generic name to Physa was the cause of 

 the error. This Mexican snail has a Glandiniforra shell, and 

 Mr. T. believed that its nearest relation would probably be with 

 Grlandina. The Physella Berendtii is described as a fluviatile 

 moUusk in Mr. Binney's work on the Mollusca of N. America, 

 recently published by the Smithsonian Institution, and since, in 

 Mr. Diill's paper on the classification of Limnseidge, published 

 in the Annals of the N. York Lyceum of Nat. Hist. There is ■ 

 nothing contained in the original description of the species or 

 in subsequent reference to it by European authors, to cause a 

 doubt of its being terrestrial. 



Mr. John S. Phillips presented to the Section the MSS. (and 

 colored drawings of the plates) of Spix's Testacea of Brazil.
