NEW SPECIES OF MARINE SHELLS. 242 
delicately transversely grooved. This may be more apparent in a fresh 
specimen, ours being rather worn shells. At the sutures there is a deep 
channel ; the mouth is simple, white within. 
One or two specimens ; rare. 
CERITHIOPSIS (SEILA) BANDORENSIS, sp. nov. (PI. 1, f. 19.) 
C. test attenuata, brunned, solidd, anfracttbus duodecim, ad apicem 
pallidis, transversim quadriliratis, liris rotundis paullum diversis, majori- 
bus minoribus alternantibus, vel binis cequalibus, tertid minore, aperturd 
rotunda, labro simplice, margine columellari recto. 
Long. 7 mill. (sp. maj.). 
Matin: 
Hab. Bombay (Abercrombie). 
A plain brown transversely round-ribbed species, a little like Tele- 
scopium fuscum in miniature as regards sculpture, but not so broad 
proportionately as that species, being uniformly attenuate. The apex 
is whitish, whorls about 12, transverse ribs somewhat varying in size 
about four in a whorl, 
Rare. ‘Two specimens only. 
CYCLOSSTREMA SOLARIFLLUM, sp. nov. (PI. 1, f. 20.) 
C. testa minutd, albescente, tenui, depressd, profundé umbilicatd, an- 
fractibus quatuor, ultimo rapide accrescente, undique transversim tenui- 
livatis, infra suturas binis gemmularum ordinibus decoratis, et ad basin 
circé umbilicum similt modo bigemmulatis, apertura rotundo-ovatd, labro 
sémplice. 
Long. 0°50 mill.

Hab. Bombay (Abercrombie). 
A very small shell, with some of the aspect of a small Torinia ; it 
also, to some extent, resembles C. tate: (Angas), from 8, Australia, 
but the double row of gemmules on the lirze below the sutures, and at 
the base, around the umbilicus, distinguish it from that species. 
Not uncommon in shell sand. 
Surely Cyclosstrema is neuter, being instituted by the late Captain 
Marryat, R.N., the famous novelist (who added the study of the 
Mollusca to his many other accomplishments), in 1817, as derived from 
xixdos aNd renux, It has been considered feminine by most writers 
and authors, including Captain Marryat himself.
