* This species was named Thalassema rupium by Lamarck in 1801, but not 

 desoribed ; and the references he gives to the figures of Pallas and the Encyc. 

 Method, represent the Sipinicuhts cdidis. Sa\igny was the next to name it, 

 which he did by calling it Thalassema mtlgaris. He describes it at some 

 length (1809), and refers to the proper figures of Pallas &c. I have therefore 

 followed Forbes and Goodsir in preserving the specific name given it by this 

 eminent naturalist.
