man of his lime iias done more, few hâve done as much, 

 to promole the siudy of Ihe Mollusca, and in him France 

 has lost one of her niosl distinguished men of science. . . . 



» Il is wilh the Journal of Conchyliologie Ihal Crosse's 

 memory will be for ever associated. Hisnamefirsl appears 

 on Ihe titlepage of that periodical in 1861, and il is nol 

 too much to say Ihal lo him and his distinguished col- 

 league, D^ P. Fischer, who, considerabily Ihe younger 

 man, predeceased him by nearly half a décade, is due 

 Ihe entire crédit of carrying on for more than thirty years 

 a publication which has consistently maintened the highest 

 standard of excellence in the articles which hâve appeared 

 in ils pages. . . 



» Crosse's knowledge of the Mollusca v^^as nol confined 

 to any spécial group or groups, but was far reaching and 

 comprehensive. Nalurally, his acquainlance wilh analo- 

 mical détails was subordinale to his .familiarity wilh 

 other portions of the study. The Land Mollusca of New 

 Caledonia and of Mexico are perhaps the Iwo fields on 

 which he will be found lo hâve left raost permanent traces 

 of his ability. . . 



» He was especially fond of calaloguing the Molluscan 

 fauna of islands. Some of his lists, thus compiled, are 

 invaluable to the studenl of geographical distribution, 

 remarks upon which generally accompanied the lists. . . 



» I believe Crosse possessed a spécial sympalhy for 

 England and English Avorkers. Certainly his encourage- 

 ment of young contributors was charming, and his cour- 

 tesy uever failed. His knowledge of English was remar- 

 kable, and he was capable of Iranslating articles from 

 that ianguage inlo Freuch wilhoul missing the smallesl 

 point or losing the mosl délicate shade of meaning. 

 Besides possessing numerous other titles of honour, he 

 was a Corresponding Member of the Zoological Society
