The smaller figure is of the size of nature. 



Observations. A single specimen of this pretty little 

 species was found in the sand of the box in which the 

 specimens came, by a young conchologist of my family. 

 I promised him that it should be his species, should it 

 prove new, of which, on examination, I have no doubt. 

 The radiating striae are closer as well as longer, and more 

 numerous below than above. 



S. ornatum. Plate 4. Fig. 108. 



Description. Shell convex above, flattened below, fur- 

 nished with many granular transverse lines, three of 

 which, on the superior part of the whorl, are larger than 

 the others, furrowed on both sides of the carina which is 

 crenulate, longitudinally striate ; substance of the shell 

 rather thick ; suture furrowed ; umbilicus very wide, per- 

 spective, beautifully crenate at the edge, furrowed within 

 and longitudinally striate ; whorls six ; mouth subor- 

 bicular. 

 Length .2, Breadth 9-20ths, of an inch. 



Observations. This species is very like Branders's figure 







of Turbo canaliculatum, and Sowerby's figure of the same 

 species, Solarium canaliculatum, plate 524. On compari- 

 son, however, with a specimen from Hampshire, sent to me 

 under that name, I find them very different ; the umbilicus 

 being much wider in the species from Claiborne, which is 

 also more carinate, and has smaller and more numerous 

 granulate lines.
