104 THE NAUTILUS. 
Nearctulas, ?. Californica and its allies, differ from those of the in- 
terior in wanting the crest behind the outer lip. 
From a study of Morch’s description and figures in the American 
Journal of Conchology, vol. 1V, p. 380, pl. 8. f. 6-9, it is obvious 
that Pupa hoppii Moller is not identical with ?. decora. Binney’s 
ficure in Man. Amer. L. Sh., ft. 190, does not represent the true 
hoppti ; and no reliable record of its occurrence ontside of Green- 
land has been made.

IN MEMORIAM—M. H. CROSSE. (1) 
BY REV. A. H. COOKE, KING’S COLLEGE, CAMBRIDGE, ENG, 
The scientific world in general, and malacologists in 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 Vernon, 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 Tronchet, Paris, and wondering whether I 
should eall 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 1851 that Crosse contributed his first paper 
(Notice sur Uhabitat du Panopxa aldrovandi de Sicile) to the 
Journal de Conchyliologie, 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 ; Kiener had suspended his; the Adams Genera, 
Philippi’s Handbuch, Gray’s Guide, Woodward's and Chenu's Man- 
ua/s were yet to appear. (Geographical distribution, as a serious study, 
was absolutely unknown. 
It is with the Journal «ie Conechyliologie that Crosse’s memory 
will be forever associated. His name first appears in the title page of 
that periodical in 1861, 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
