104 THE NAUTILUS. 



Nearctulas, I'. California! and its allies, differ from those of the in- 

 terior iu wanting the crest behind the outer lip. 



From a study of Morch's description and figures in the American 

 Journal of Conchology, vol. IV, p. 80, pi. 3. f. 6-9. it is obvious 

 that Pupa Jioppii Moller is not identical with P. decora. Binney's 

 figure in Man. Araer. L. Sh., f. 190, does not represent the true 

 hoppii ; and no reliable record of its occurrence outside of Green- 

 land has been made. 



IN MEMORIAM-M. H. CROSSE. (1 



BY REV. A. H. COOKE, KING'S COLLEGE, CAMBKIlMiE. E\<i. 



The scientific world in general, and malacologists iu particular, will 

 have learned with profound regret the news of the death of M. Joseph 

 Charles Hippolyte Crosse, which took place on August 7, 1898, at 

 his country .residence, the Chauteau d' Argeville, at Vernou, near 

 Paris. No man of his time has done more, few have done as much, 

 to promote the study of the mollusca, and in him France has lost one 

 of her most distinguished men of science. It was one of those strange 

 coincidences that sometimes occur to us all, that I should have been 

 walking down the Rue Trouchct, Paris, and wondering whether I 

 should call at No. 25, only the day before I returned home to hear of 

 his death, and receive the request to write this obituary notice. 



Born in 1827, it was in 1S51 that Crosse contributed his first paper 

 (Notice sur I'habitat du J'anoprea a.ldrovandi de Sidle) to the 

 Journal de Conchy liologie, which was then in the second year of its 

 existence, edited by M. Petit de la Saussaye. It gives some idea of 

 the strides which the science has made since those days to learn that 

 then malacology was still governed by the systems of Lamarck and of 

 Cuvier. Reeve, Sowerby and Kuster had but recently commenced 

 their iconographies ; Kieuer had suspended his ; the Adams Genera, 

 Philippi's Handbuch, Gray's Guide, Woodward's and Chenu's Man- 

 uals were yet to appear. Geographical distribution, as a serious study, 

 was absolutely unknown. 



It is with the Journal <le Conchy liologie that Crosse's memory 

 will be forever associated. His name first appears iu the title page of 

 that periodical in 1.801 . and it is not too much to say that to him and his 

 distinguished colleague, Dr. P. Fischer, who, considerably the younger 

 man, pre-deceased him by nearly half a decade, is due the entire
