106 AMERICAN JOURNAL 



by Dr. Newcomb for a California species, I propose to desig- 

 nate my species by the name of H. Parkeri, dedicated to Mr. C. 

 F. Parker, of Philadelphia. The description is in Am. Jour. 

 Conch., ii., p. 303, Oct., 1866. G. W. T., Jr. 



On Valvata Jelskii, Crosse. — By Prof. 0. A. L. Morch, 

 (In a letter to the Editor ) " The species described and figured 

 by M. Crosse under this name (Jour, de Conchyliologie, 1863, 

 p. 382, pi. 13, f. 3,) is the young of Lithoglyphus. I found it 

 on some specimens of Lithoglyphus from Mr. Crosse. The old 

 shells were covered with a vesicular clayish coat, and each vesicle 

 contained a single so-called V. Jelskii. — Copenhagen, Aug. Qth,

OBITUARY. 

 Augustus Addison Gould, M. D. 



This illustrious conchologist died suddenly of cholera, in 

 Boston, on the 15th of last September, aged 61 years. He was 

 a man of highly cultivated mind and liberal views, and attained 

 a distinguished rank in other branches of science besides that 

 which was his favorite study, and by which he is best known to 

 our readers. 



As one of our earliest conchological authors. Dr. Gould aided 

 much in the description of our native shells ; afterwards his ex- 

 tensive knowledge of the science caused him to be selected by 

 the United States Government to describe the collections made 

 by its exploring expeditions. He was an indefatigable worker, 

 and his descriptions are models of accuracy and perspicuity. In 

 his general acquaintance with the science in all its branches he 

 was perhaps unequalled by any other American student, and the 

 immense stores of his knowledge as well as his time were always 

 so freely at the service of every one who pursued the study of 

 the mollusca, that his influence upon the progress of the science 

 among us can scarcely be overestimated, and certainly far ex- 

 ceeds that exerted by the works he w^rote, — valuable and numer- 

 ous as they are. The latter comprise :
