STROMBUS PELICAWS FOOT. 91 



STROMBUS Pes Pelicani* 

 PELICAN'S FOOT. 



Specific Character. Shell turreted, finely 

 striated transversely ; spire tapering to a fine 

 point with ten tuberculated convolutions; the 

 body whorl has two rows of smaller tubercles 

 beneath the larger ones ; outer lip much ex- 

 panded, four-clawed, the upper claw extending 

 up the spire, the lower one forming the beak ; 

 the two middle ones are ribbed along the back 

 in a continued line from the rows of tubercles, 

 and underneath is a corresponding groove. The 

 shell is of a pale brownish flesh colour. Length 

 nearly two inches. 



The Strombus Pes Pelicani is subject to 

 great variations in the different stages of its 

 growth. In young shells f the outer lip has not 

 assumed its peculiar form ; it first gradually 

 expands, then the claws appear, and finally it 

 becomes digitated. Shells are found in all the 

 intervening gradations between the young and 

 the adult specimen. 



This species is rather common on many of the 

 coasts of Great Britain, it is chiefly met with on 

 sandy shores.
