Two specimens were brought ; one is three-fourths of an inch 

 long and nearly half an inch broad. They differ from the general 

 appearance of the shell by having no longitudinal folds, and by 

 having the whorls rounded, and not flattened above ; the colu- 

 mella too has only a single obsolete plait. There can be little 

 doubt, however, that they belong to this species, which is stated 

 to be very variable in form. 



Fusus Sabini, Gray sp. PI. V. fig. 10. 

 Buccinum Sabinii, Gray, Append. Parry's 1st Voy. p. 211. 



A single specimen of a Fusus resembling F. Islandicus was 

 procured ; it is undoubtedly distinct from that species, but is 

 probably the Buccinum Sabinii of Gray. It differs from it how- 

 ever in some respects, particularly in the canal, which in B. Sa- 

 binii is stated to be shorter than that of F. Islandicus, whilst in 

 the shell brought by Messrs. Warham and Harrison, it is longer. 

 It is much thinner than any of the varieties of that species with 

 which I am acquainted ; and the whorls, which are covered with 

 rather strong, raised spiral lines, are more ventricose, and are de- 

 cidedly flattened above at the sutures : the canal is not only longer 

 but is more contracted at its commencement, and widens a little 

 towards the front or apex ; the mouth is therefore better defined, 

 and is much more rounded ; including the canal, it is consider- 

 ably longer than the spire. The columella is pellucid, and the 

 epidermis very pale, horn- coloured and delicate. Length upwards 

 of li inch ; breadth \\ inch. 



Fusus pellucidus, n. s. PI. V. fig. 3. 



Shell fusiform, elongated, thin, glossy, of a yellowish horn- 

 colour, pellucid; spire much produced; whorls seven, well rounded ; 

 sutures deep, with rather distant, strong, but very slightly raised 

 spiral striae, and strong, smooth, longitudinal close-set ribs or 

 plaits, most conspicuous on the second, third and fourth whorls, 

 and becoming obsolete on the body -whorl and apex ; mouth con- 

 siderably shorter than the spire, elliptical, terminating in a short, 

 wide canal, slightly recurved ; columella smooth ; outer lip thin, 

 with the interior crenulated in conformity with the exterior stria?. 

 Length § inch; breadth A inch. 



This species, of which only one individual was procured, is very
