Length about one-tenth of an inch. Inhabits the Southern 

 coast. 



Animal. — Foot shorter than the shell, oval; tentacula rather 

 robust, filiform, half as long as the foot ; eyes at the external base 

 of the tentacula. 



I have obtained but a single individual of this species. If it is 

 only an immature specimen, we know nothing of the parent of 

 it. 



Turbo palliatus. — Shell suboval, not remarkably thickened ; 

 whirls four or five, wrinkled transversely ; spire short, convex, 

 obtuse, much shorter than the aperture; suture moderately in- 

 dented. 



Length about one-third of an inch. Greatest breadth about the 

 same. Inhabits the shores of the New England States. Cabinets 

 of Mr. Aaron Stone, Mr. Wm. Hyde and my own. 



This species was found by Mr. Aaron Stone on sea-weed, about 

 low water mark. It is often variegated with olivaceous and white, 

 or green and yellowish, so as to exhibit a reticulated appearance ; 

 but they are veiy frequently covered with a greenish, or red- 

 dish-brown pigment, and sometimes with a plain yellowish-white 

 immaculated one. The shell within is very often of a dark red- 

 dish-brown color, with the oral margin whitish ; but the same part 

 is sometimes entirely whitish. 



Turbo obligatus. — Shell suboval, not thickened ; whirls five, 

 transversely wrinkled, and longitudinally striated with obtuse 

 slightly elevated lines ; spire short, much shorter than the aperture ; 

 suture indented. 



Length about one-third of an inch. Greatest breadth about the 

 same. Inhabits Portland, Maine. Cabinets of Messrs. Stone, 

 Hyde and Say. 



This species strongly resembles the preceding, but is distin- 

 guished by the elevated, obtuse, revolving lines, or acute impressed 

 ones. The colors are greenish, olivaceous, or whitish, with darker, 

 irregular, transverse lines or shades, and the throat is dark reddish- 

 brown, the margin of the mouth whitish. It is vciy possible that 

 it is only a variety of the preceding. 



Turbo vestita. — Shell conic, rather thin ; whirls about six, 

 rounded, transversely wrinkled ; spire as long as the aperture ; 

 suture deeply impressed.
