fariam varicosis, costellis brevibus intermediis j varice ultimo lato, tenui, radia- 

 tim striate, canali longiusculo, obtecto. 



Distinguished by the tenuity and great extent of the wing-hke 

 varix from all known species. 



MUREX DOMINGENSIS. Pl. X. fig. 5. 



Testa subovata, utrinque subacuminata, trifariam varicosa, anfractibus senis, longi- 

 tudinaliter costellatis, spiraliter valide striatis ; varicibus prominentibus, rotim- 

 datis, marginibus paucispinosis, spinis brevissimis ; labio columellari antice rugu- 

 loso ; canali breviuscula. 



Pyrula Consors. 



Testa obovata, ventricosa, laevis, transversim striata ; anfractibus quinque, primis 

 tuberculatis, ultimo seriebus duabus ad tribus postice, antice serie solitaria or- 

 natis ; apertura oblonga, lata ; canali lato, brevi ; columella antice subangulata, 

 planulata. 



This species nearly resembles P. Melongena, Lam., which is a re- 

 cent species from the West India islands : it may be distinguished by 

 its shorter figure, by being more ventricose, by the pointed tubercles 

 on the spire, and its shorter and wider canal. 



Fusus Henikeri. 



Testa elongato-fusiformis, gracilis, postice elongato-acuminata, anfractibus pluri- 

 mis, ventricosis, longitudinaliter costiferis, spiraliter liratis, costis rotundatis, 

 liris acutis ; canali elongata, extus lirata, margine interuo labii columellaris 

 ruguloso ; labii externo intus sulcato. 



Remarkable for being distinctly longitudinally ribbed and spirally 

 grooved ; the inside of the outer lip is also grooved, and the inner 

 edge of the columellar lip is rugulose. 



Fusus Haitensis. 



Testa elongato-fusiformis, gracilis, postice elongato-acuminata, anfractibus pluri- 

 mis, ventricosiusculis, undique spiraliter liratis, liris prominentibus acutis, me- 

 diana duplicata majori, longitudinaliter costatis, liris costas decussantibus ; ca- 

 nali valida, liris posticis distinctis, anticis subobsoletis. 



Most like F. Toreuma, Desh., but distinguished by the central ele- 

 vated ridge being formed of two lines, and being more prominent than 

 the remainder. 



Fasciolaria semistriata. 



Testa oblongo-fusiformis, anfractibus senis, antice posticeque spiraliter striatis, 

 mediane Isevibus ; striis duabus elevatis prope suturam conspicuis. 



This species most nearly resembles F. fusiformis of Reeve ; it may, 

 however, be easily distinguished, by the middle part of the volutions 

 being free from the spiral strise. 



Fasciolaria intermedia. 



Testa oblongo-fusiformis, anfractibus senis, primo laevi papilliformi, secundo, tertio 

 et quarto tuberculatis, cseteris ventricosis, Isevibus ; canali longiusculo. 



A single specimen with a papillary apex, like that of i^. papillosay
