he was pointing at. 1 have accordingly quoted both of his figures here for Dr Gwyn Jeffreys' 

 species. As to Horaces, I have quoted him on the authority of Dr Gwyn Jeffreys (Brit. Conch., 

 loc. eit. supra) ; but his species (which he erroneously identified as Buccinum corrugatum, Broc.) is, on 

 both the outer and inner lip, " init starken Ziihnen versehen," which is not the case with Dr 

 Jeffreys' species. If, however, Horaces' species be really that of Dr Jeffreys, then probably 

 Michelotti's name of harpula will have priority. It is obvious that there is here a whole group of 

 ' Columbellas greatly in need of revision.

Shell. — Eather small, short, and dumpy, with a high blunt spire, a small last whorl, a 

 very contracted base, from which projects a small, slightly reverted snout ; the whorls are 

 longitudinally chamfered, and have a small beaded thread round the top. Sculpture: 

 Longitudinals — there are on each whorl about 13 straight, narrow, ridge-like, but low 

 riblets, separated by shallow furrows of two to three times their breadth ; these ribs and 

 furrows run pretty continuously down the spire, with a slight sinistral twist ; toward the 

 mouth and on the base they become feeble, but are faintly traceable on the snout. The 

 whole surface is finely scored with lines of growth. Spirals — the suture is inferiorly 

 margined by a slight thread, which rises into small beads in crossing the riblets ; in the 

 longitudinal furrows a faint tendency to spiral scratches is visible, which on the base 

 arrange themselves into narrow and very superficial furrows with broadish flat threads 

 between ; these become strongish and narrower on the base of the snout, but feebler again 

 towards its front. Colour: glossy porcellanous white. Spire rather high, narrow and 

 conical. Apex a small round dome of two glossy embryonic whorls, of which the extreme 

 tip is both immersed and flattened down with scarcely any suture. Whorls 8 in all, 

 conical, with straight sides, short and broad ; at the top each projects very shortly and 

 horizontally ; the last is small, with a rapidly contracted base, from which projects the 

 small slightly reverted snout. Suture a very little impressed, but strongly marked by 

 the projection of the whorl below it. Mouth small, rather rhomboidal, pointed above, and 

 produced below into a short open squarish canal. Outer lip very straight to the corner of 

 the base, from which it is patulous and curved ; in the middle one small round tubercle 



1 Strix, a chamfer.
