MELVILL : NEW MAEINE SHELLS FROM BOMBAY. 109 



Solariitlse, Scalariidoe, Pyramidcllidoc, and Ccritliiida), will swell up 

 the total of tliose catalogued to 350 species. 



I would tender my best thanks, not only to Mr. Abcrcrombie, for 

 providing the material of which this paper is the outcome, but also 

 to Mr. E. A. Smith and Mr. E. R, Sykes, for aid and advice. It is 

 my intention to offer to place the typos of all these small species in 

 the Natural History Museum, South Kensington. 



1. BrTTIUM TENTHRENOiS, U.Sp. PI. VIII, Fig. 1. 



B. testa cylindrica, obesula, doliiformi, solida, ochracea, apice 

 Dbtuso, apud apicem, simul ac ad basim pallidiore, anfractibus 7, in 

 medio latioribus, tribus papillarum ordiuibus trausversim regulariter 

 mstructis, papillis parvis, gemmatis, interstitiis alveolatis, apertura 

 jvato-rotunda, labro exteriore minime expanso. Long. 3, lat. 1'25 mm. 



About twenty specimens of a small, tun-shaped, cylindrical shell, 

 tvarm ochraceous in colour, with the extremities pale, almost white, 

 Drnamented with three rows of papilliform gemma) on the whorls, 

 the spaces between them being alveolate, whence the specific name, 

 ierived from TeuOpijvwrij^, ' honeycombed.' This species is slightly 

 like Cerithiopsis pulvis, Issel, from the Red Sea, a very small species, 

 which, with the present one, I should be inclined to class rather 

 as a Bittium. 



2. Cerithiopsis eubricincta, n.sp. PI. VIII. Fig. 15. 



C. testa fusiformi, solida, pallide ochracea, anfractibus 10 vel 11, 

 tumidis, apud suturas impressis, binis gemmarum ordinibus trans- 

 versim decoratis, lougitudinaliter clathratis, interstitiis alveolatis, 

 infra juxta suturas tenui rubra zona accinctis, apertura subrotunda, 

 peristomate tenui, canali brevi. Long. 3*25 mm. sp. maj., lat. 1mm. 



Very beautiful, though minute. Of a pale ochraceous colour ; the 

 ventricose whorls are ornamented, just below the sutures, with a red 

 band ; the sculpture is, as is usual amongst the Triforis^ Bittium, 

 and Cerithiopsis, a double row of transverse gemmae, crossed by lattice- 

 forming riblets, the interstices being honeycombed and deep. The 

 mouth is almost round, canal very short, lip simple. Several 

 specimens. 



3. Cerithiopsis Stkesii, n.sp. PI. VIII, Fig. 8. 



C. testa attenuato fusiformi, aciculata, ochracea, anfractibus 12 

 vel 13, rectis, minime ventricosulis, trinis gemmarum papilli- 

 formium ordinibus trausversim cingulatis, apud suturas impressis, in 

 uno specimine juveni duobus apicalibus anfractibus pellucidis, vitreis, 

 apertura sub(p;adrata, simplice. Long. 4-25, lat. l'20mm. 



A tropical representative of the typical species of the genus, 

 C. tuhercularis, Mont., from which this shell differs in being straighter, 

 more attenuate, and regular. It comes nearer to the C. diadema, 

 AVatson, from Madeira, of which I have only seen a figure, but is 

 smaller than that species. It is of a uniform pale ochraceous-brown, and 

 the single young individual of the series possesses two vitreous apical 

 whorls intact. I have much pleasure in connecting with this small 

 Cerithiopsis the name of Mr. E. R. Sykes, our indefatigable Secretary.
