/ Z FUSUS. 



latiuscula, anfractibus 12 rotundis, spiraliter liratis superi- 

 oribus rotundo-plicatis, ultimo vix plicato, globoso, magno, 

 cauda breviuscula, angusta, apertura rotunda. — Remarkable 

 for the fulness of the last whorl. 



13. DrjpETiTTHOUARSi, f. 5, Reeve. — Testa ventricoso-fusi- 

 formis alba, lineis rubris longitudinalibus hinc illic ornata, 

 anfractibus 11 rotundis spiraliter acute liratis, superioribus 

 plicato-costatis, ultimo globoso, magno ; apertura magna, 

 margine crenato, aurantio rubescenti. — The middle whorl is 

 nearly as ventricose as in F. nobilis. The whorls are sharply 

 ridged. The margin is generally orange-red, the edges of 

 successive margins appearing at intervals on the surface of 

 the whorls. 



14. OBLITUS, f. 16, 17, Reeve. — Testa fulva, flammulis 

 fuscis strigata, costis subplanulatis interstitiis linearibus 

 cincta, spira acuminata ; anfractibus angulatis, ad angulum 

 tuberculatis, supra angulum planulatis, subexcavalis, ultimo 

 ventricoso, supra canalem brevissimo.— Differing from F. 

 colus and similar species in having smooth flattened ribs with 

 narrow interstices. It is also more ventricose, and the 

 body whorl more globose, and suddenly cut off from the canal. 



15. colus, f. 14, 15, Limiceus. — Testa angusta alba, 

 versus extremitates ustulata; spira acuminata, anfractibus 

 12 plus minusve angulatis, ad angulum acute tuberculiferis, 

 inter tuberculas fusco maculatis, omnino subdistanter spira- 

 liter liratis, inter liras tenuiter striatis ; ultimo brevi, cauda 

 gracillima versus terminum flexuosa. — The want of distinct 

 keel and tubercles at the angular or subangular part of 

 the whorls, and of intermediate spots, are the reasons given 

 for distinguishing the var. f. 14 as F. longicauda, Reeve, as 

 of Borg. It is singular, however, that the fig. referred to is 

 that of a very angulated shell. The differences are such as 

 obtain between individuals of most species. 



16. toeeuma, f. 12, 13, Lamarck. — Testa quam F. colus 

 latior, laBvior, anfractibus late angulatis ventricosis tuber- 

 culatis inter-maculatis, et strigatis ; aperturae margine ex- 

 panso, crenulato. — On the whole, shorter and wider than F. 

 colus. The aperture, when mature, is somewhat expanded 

 and crenulated at the margin. 



17. Sandvichensis, f. 25, Sowerby. — Testa alba, tenuiter 

 lirata ; spira elongata, anfractibus 11, superioribus rotundis 

 rotunde plicatis ; ultimo angulato ; canali spiram longitudine
