Pretiminary Nore on THE ANATOMY OF THE GENUS C'ATAULUS. 
(Read 12th December, 1902.)—The genus Cataulus, at present included 
in the subfamily Pupinine, is restricted exclusively to the Cingalese 
district, and the twelve species (eleven of which are terrestrial and one 
arboreal) I have worked at were obtained by Mr. O. Collett at altitudes 
between 500 feet and 4,000 feet. All bear a striking resemblance to one 
another, both as regards their external appearance and their internal 
anatomy, and differ only m minor details. 
Among other interesting points about the genus is the fact that it 
possesses many rhipidoglossate characteristics, pre-eminently as regards 
(1) the nervous system, (2) the kidneys, (3) the looping of the intestine, 
(4) the epipodium ; while on the other hand it has a teenioglossate radula 
of littorinoid form. Further, it has neither gill nor lung, the mantle 
acting as a pulmonary sac. Air is introduced into the mantle-cavity 
through an opening within the peristome ; this communicates with a tube 
which traverses the last whorl of the shell. Possibly the left kidney 
(cf. the papillated sac of-7vrochus) acts as a lung. Partly between the 
right and left kidneys and partly between the left kidney and the intestine 
there lies a pigmented sac, containing two species of Infusoria, hitherto 
unidentified. 
In a forthcoming paper the anatomy of Cataulus will be more minutely 
described, and its affinities discussed, revealing a close relationship to the 
Paludinide. Lertice Diasy. 
Nove ON THE DATES OF PUBLICATION OF J. E. GRay’s “ CATALOGUE OF 
PULMONATA . . . INTHE .. . British Museum. Pt.. I,” 12mo, 1855 ; 
AND oF A. Moaqurn-Tanpbon’s “ HISTOIRE NATURELLE DES MOLLUSQUES 
TERRESTRES ET FLUVIATILES DE FRANCE,” 2 vols. 8vo, 1855. (head 
9th January, 1903.)—These two authors having proposed new names 
in their respective works, that in one case at all events relate to the same 
species, 1t became necessary to find out which should have precedence. 
From inquiries instituted at the British Museum it appears that Gray’s 
work was completed early in April, 1855, and issued by the 18th of the 
same month. 
Through the kindness of Messrs. Dulau & Co. the following particulars 
concerning Moquin-Tandon’s work have been extracted from their copy of 
the “ Bibliographie de la France,” the additional details ascertained by 
computation being added in[ | :— 
Livr. 1 and 2, 17 sh. [= vol. i, pp. i-vili, 1-256]: 14, vii, 1855. 
Livr. 3, 10 sh. [= vol. i], pp. 257-416; 9 pls. : 18, vill, 1855. 
Livr. 4 and 5, 23 sh. [= vol. ii, pp. 1-368] : 19; i, 1856. 
Livr. 6 and last, 17 sh. [= vol. 11, pp. 369-646]: 26, iv, 1856. 
Hence it appears that the whole of the systematic portion, or vol. ii, was 
issued in 1856, and not, as dated on the title-page, 1855. 
Gray’s names consequently have precedence over Moquin-Tandon’s, as, 
for example, Jilax, Gray, which supersedes Amalia, Moquin-Tandon.
