MELVILL AND STANDEN : SHELLS FROM LIFU. 299 



B. albocinctum sp. nov. (PI. X., fig. 47). 



B. testa minuta, cylindrica, ad apicem aftenuata, apice 

 obtuso, anfractibus octo, tribus gemmularum ordinibus seria- 

 tim dispositis, uno ordine infra, juxta suturas, albido, duobus 

 pallide ochraceis, ultimo anfractu albido, bicingulalo, aper- 

 tura ovata, labro simptiee, canali brevi. 

 Long., 4, Lat., 175 mill. 



A very pretty species, of which we have seen two or three 

 specimens. Much resembling in sculpture B. uveanum, but 

 differing in the mouth being larger, the shell less tun-shaped, 

 and in the coloration. These two Bittia belong to the same 

 section of the genus as B. pulvis Issel (described by the 

 author a sa Cerithiopsis), and B. tenthreno'is Melv., described 

 in Proc. Mai. Soc, 1896, vol. 2, No. 3, p. 109, from Bombay. 



B. marileutes sp. nov. (PI. X., fig. 48). 



B. testa minuta, cylindracea, nigro-brunnea, condensata, apud 

 apicem obtusata, anfractibus octo, duobus apicalibus, cceteris 

 transversimpapilliferis triseriatis, papillis gemmulatis nitidis, 

 regularibus, apertura rotunda, labro simptiee. 

 Long., 2 "50, Lat., 1 mill. 



One of the smallest if not the most minute of the genus. 

 An almost pitchy-black little species, with eight close-grained 

 whorls ; the whorls are adorned with three transverse rows of 

 papilliform gemmae, black, shining. Mouth simple, very small. 

 Three specimens. (fjLapiXevrqs, a charcoal burner, from the 

 colour). 



B. uveanum sp. nov. (PI. X., fig. 49). 



B. testa minutissima, dolioliformi, nitida, violacea, in speci- 

 mine juniori apicalibus quinque albidis, quam maxime 

 attenuatis, anfractibus novem, apud suturas impressis, tribus 

 spiralium gemmularum ordinibus regulariter accinctis, gem- 

 mulis nitidis, nodulosis, interstitiis planatis, ad basim infra, 

 si mul ac ad apicem supra, multum attenuatis, apertura 

 parva, ovata, labro simplice, canali brevissimo. 

 Long., 3*25, Lat., 1*25 mill.
