Grant Expedition, 1898-99, is a Buliminits {mirnhilis 3m.) partu- 

 loid, with hidentate peristome, the smaller B. rotioidus Sm. being 

 also similar, and remarkable. The subgenus Ovella has several 

 representatives in B. longifonnis and several others of tlie group 

 in which oblique, bizarre, zebra-like markings are conspicuous, 

 the peristome being only slightly thickened. In fact, the genus 

 /hili??nnus is the most higlily represented here. Several very 

 highly sculptured Lithidion, and large Otoponia, are among the 

 operculates, while of Stenai^yra there are large, but plain, varieties. 

 One ])eculiarity in the Socotran land mollusca seems to 

 be a total absence of He/icidce proper. Ennea is present in 

 one or two peculiar forms, whilst, among fluviatile species, a 

 Pla}iort>is seems to abound, ap,d the almost cosmopolitan 

 Melania tuherciilafa L.

This very fine addition to the genus Coitus has just been 

 described in the A)in. &-• Mai^: iV. If., December, 1899. It 

 combines the graceful form and size of C. (gloria maris Chemn. 

 (perhaps its nearest congener) with C. fpiscopus Hwass, the 

 markings of which it much assimilates. 



Referring to a revision of the section Cy/iudt-r of Cojitts, 

 propounded by myself in 18S5, I should suggest that this new 

 species {C. clyiospirci) form a separate section by itself, which 

 section would be amply characterised by the extended spire, 

 increasing longitudinally i| in. in the type specimen, and also 

 l)y the indented upper whorls, a character not noticed in any 

 other species of Cylinder proper. The extreme attenuation of 

 the last whorl seems distinct from all other species save C. i^/oria- 

 inaris. C. civtospira should, therefore, be placed between the 

 Text ilia pyrainid alia (to which C. i^loria-tnaris, C.pauluccicP,^r\(S. 

 C. /ei;a///s are referred, as well as C. /i ramidalis) and the Aulici, 

 subdivision {a) Episcopi, to which C. episcopus Hwass belongs. 



The new species was discovered about September 7th, 1899, 

 by Mr. F. W. Townsend, in the Arabian Sea, 100 miles due 

 west of Bombay, adhering to the Eastern Telegraph Company's 

 cable, which had been hauled up from 45 fathoms, as it needed
