Inhabits the Nicobar Islands. Chemnitz. 



Shell sometimes about an inch long, and hardly three-quarters 

 of an inch broad, but is generally rather smaller ; the upper 

 valve is described by Linnaeus to be variegated with black 

 and white undulated stripes and veins, and the under valve 

 white ; Chemnitz says that the colour is extremely variable, 

 but he has quoted Pecten disturtus of Da Costa, and has 

 referred to some figures which obviously belong to O. varia ; 

 this reference to Da Costa probably misled Montagu to 

 quote both of Chemnitz's figures for P. distortus, but they 

 appear to be different.

 about forty-five unequal filiform ribs, and the

 Inhabits the coasts of Britain. Lister, #c. 

 This strange shell is sometimes two inches long, and an inch 

 and a half broad, and of such a distorted growth that no two 

 are found alike ; the lower valve partakes of all the inequa- 

 lities of the rock or shell to which it is affixed, and the upper 

 valve is also much distorted ; the colour is most commonly 

 reddish brown or red mottled with white. 



mini ata. 34. Shell sub-ovate, with numerous mu- 

 ricated filiform ribs, and the auricles nearly 

 equal.
