THE RED PECTEN. 



upper one is richly banded with concentric rings of 

 red and pink. The choice specimen from which this 



drawing was made, kindly sent from Oregon by Mr. 

 Dore, is two and a half inches in diameter. Pecten 

 hericeiis, Gld., is a synonymous name. 



Amusium caiirinum, Gld., A-mu'-si-um cau-ri'- 

 num, Northwest Weather- vane. 



As the translation of this odd name indicates, this 

 very large and broad shell comes from the vicinity of 

 Puget Sound. It is a huge, flat Pecten, having 

 unequal, circular valves, marked by twenty ribs. 

 Edges thin, ears rather small, color white within, 

 yellowish brown without. Diameter about six inches. 

 Lima orientalis, Ad., H,i'-ma o-ri-en-ta'-lis, 

 Fig. 142. Shell white, delicate, oblique, the 

 valves gaping on one side. Sculpturing fine 

 and straight, like the teeth of a file. It is 

 sometimes thrown up by storms, and is found 

 Fig. 142. attached to sea-weed.
