LEPTOTHYRA RUBENS, sp. n. (PI. A. fig. 14.) 

 L. testa globosa, parva, imperforata, solida, nitidula, infra ltevissima, pallide, 

 strarainea, flammis castaneis decorata ; anfractibus 4-5, quorum If apicales 

 apice ipso vitreo-albo, mamillato, ceteris gradatulis (ultimo rotundiore), 

 undique infra medium lasvibus, nitidis, supra arete spiraliter sulculosis, 

 ultimo ad peripheriam pallide spiraliter zonato, infra ad basim pulchre 

 rubente ; apertura rotunda, labro vix incrassato, nisi marginem apud colu- 

 mellarem albo-callosum, nitidum. 



Alt. 4, diam. 4'50 mm. 



Hab. Gulf of Oman, lat. 24 Q 58' N., long 56° 54' E„ 156 fathoms. 



A highly coloured little shell, which occurred somewhat plentifully at the 

 above locality. The many specimens we have seen agree in sculpture and 

 coloration almost uniformly. Near L, lata, Montr. 



TR1CH0TR0PIS PULCHERRIMA > sp. n. (Pi. A. fig. 15.) 



T. testa tenui, supra pergracili, attenuato-f usiformi, alba vel straminea, och- 

 racea epidermide contecta ; anfractibus octo, quorum duo apicales hyalini 

 laaves, cseteris multum apud suturas impressis, spiraliter acute bicarinatis, 

 ultimo quadricarinato, epidermide quasi-costulas longitudinales setulosas 

 arete prsebente ; apertura late ovata, in typico specimine aurantia, in 

 minore alba, labro effuso, tenui, columella fere recta. 



Alt. 24, diam. 12 mm. (sp. maj.). 



Hab. Gulf of Oman, on telegraph-cable, lat. 27° 12' N., long. 51° 50' E., 

 25 fathoms. 



We have already* described another species of this usually Arctic genus from 

 the Gulf of Oman, viz. T. Toionsendi — a much smaller form. The present is 

 far handsomer, being conspicuous for its graceful, rapidly attenuate whorls, 

 much impressed suturally, the upper whorls twice, the lowest four times cari- 

 nate. Two examples so far only obtained, the perfect larger example orange- 

 mouthed, the smaller white. A third species, as yet undescribed, has lately 

 been found to occur in small quantity in the dredging at 156 fathoms in the 

 Gulf of Oman. 



SOLARIUM (TORINIA) CERDALEUM^, sp. n. (PI. A. fig. 16.) 



S. testa anguste umbilicata, solida, pulchre sculpturata, depresso-conica, fusco- 

 straminea ; anfractibus 5, quorum 1 J apicales pallide rufi, nitidissimi, hyalini, 

 caeteris quatuor ordinibus gemmarum spiralium, interstitiis minute unistriaiis, 

 prseditis, quorum inferi regulariter hie illic brunneo-maculatis, in penultimo et 

 ultimo anfractu ordine summo, juxta suturas, magno, gemmulato, ultimo ad 

 peripheriam tribus carinis conspicuis brunneo-maculatis, simul ac infra, apud 

 basim, septem ordinibus spiralibus decorato, duo circa umbilicum gemmulas
