JACOBINE SHELL* 
live in breadth. The markings of this shell 
are best described by the figure. The predo- 
minant ground colour is whitish, slightly- 
tinted with pale flesh. The markings are 
principally an ouange red, blended with yel- 
low breaks in the upper parts. 
The Escallops are generally called Mantles; 
from their resemblance to the folds of a 
cloak, when hanging over .the shoulders: but 
this name is more particularly applied to the 
most beautiful varieties, with some accompa- 
nying epithet. 
The animals which inhabit this family o 
shells, are of the Oyster genus, in the Lin 
naean system; and are said to move so forci 
bly as somietimes to leap out of the catche 
wherein they are taken. Their method o 
leaping, or raising tliemselvcs up, is by forcin; 
their under valve against the body on whic| 
they lie.
