Columbella peculiaris n. sp. 
Cj’liiidric-suboval, often a little distorted ; whorls 6, slowly 
increasing, the last forming about yi ; spire obtuse ; suture 
somewhat irregular or dentate ; aperture small, pointed 
above, peristome simple, columella simple, truncate. 
Pliocene, Matura. Perhaps allied to C. dnusiformis 
Kien., but of shorter and more ventricose figure. 
Mangelia micropleura n. sp. 
Subfusiform, longitudinallj’ ribbed, the ribs crossed by 
numerous .striae, of wdiich a prominent one forms an angle 
on the upper part of the whorls ; last whorl longer than the 
spire ; aperture rather narrow, lanceolate, with a .sinus on 
the posterior part of the thickened peristome. 
Pliocene, Matura. Allied to M. pulchella. The ribs 
vary considerably as to size and distance apart. It was 
denominated M . tceniata in my list of I864.

As the name given bj'^ Sowerby had been previously ap- 
plied to another Cone, I propose the name of recognitus for 
the present shell found in Haiti and Jamaica. 
Conus prototypus n. sp. 
Somewhat pyriform, finely striate anteriorly, becoming quite 
smooth on the angle of the whorls, which bears a rather 
indistinct keel ; spire mucronate, rather elevated ; aperture 
somewhat widened towards the anterior canal. 
Caroni Series, Savanetta. A cone which departs very 
con.siderably from the usual t\'pe in its swelling outlines
