twenty elevated, somewliat undulated, lines, with alternate smaller 

 ones ; lines somewhat confused on the convex side of the shell, the 

 larger lines with a few slightly elevated, very thick fornicated 

 tubercles; apex curving laterally, tip pointing upwards and not 

 elevated from the body of the shell. 



Inhabits the southern coast. 



Of this shell I found but a single specimen, which is very im- 

 perfect. It seems to correspond very well with the description of 

 G. inlorta of the coast of England, with the exception of the form 

 of the vertex, which in that species is said to turn downwards, 

 whereas, in our shell, it not only turns downwards, but the curve 

 is continued until the tip points upwards. 



Crepidula convexa. — Shell very convex, obsoletely wrinkled 

 or glabrous, One side vertical, the other oblique ; apex prominent, 

 decurved, slightly inclining towards the oblique margin, tip gene- 

 rally free and extending lower than the edge of the aperture ; 

 aperture suboval ; diaphragm less than half the length of the 

 shell, edge simply arquated. 



Length three-fifths of an inch. Inhabits the coast of the United 

 States. Cabinet of the Academy and Philadelphia Museum. 



This species is not uncommon, particularly upon our southern 

 coast. The description is drawn from what are termed dead shells, 

 but 1 have one specimen which is varied with rufous and whitish. 



Oliva mutica. — Shell suboval, white, or yellowish-white ; body 

 whirl with about three revolving maculated bands of pale rufous, 

 of which the superior one is continued upon the spire, the inter- 

 mediate one is dilated so as to be sometimes confluent with the in- 

 ferior one, which is narrowest j spire short ; suture very narrow ; 

 colimiella destitute of striae. 



Length more than two-fifths of an inch. Inhabits the southern 

 shores. Cabinet of the Academy and Philadelphia Museum. 



A common shell, varying somewhat in color ; the bands are 

 sometimes deep reddish-brown, sometimes livid, rarely all united, 

 and offering only a white line near the base. It seems allied to 

 the 0. zonalis as described by Lamarck, but is a larger species. 



BucciNUM ORNATUM. — Shell subturbinated, with about two 

 bands of arched scales. . 



Inhabits the coast of East Florida. Cabinet of Mr. William 

 Hyde.
