SPECIES DUBLE. 375 



Gorgonia placomus, in the North Sea. I suspect that 

 this is the common Scalpellum vulgare, and that Stroem 

 counted the valves only on one side, overlooking the 

 rudimentary and concealed rostrum ; and this would 

 give seven for the number of the valves. Had it not 

 been for the expression "stipite lamellosa," I should 

 have thought this might have been an unknown species 

 of Dichelaspis. 



Scalpellum ljevis. Risso. Hist Nat. cles Product, de l'Europe 



Mead., 1826, Tom. iv, p. 385. 



The chief characteristic of this species appears to be 

 indicated by its specific name. It is found in the Me- 

 diterranean, attached to Cidarites. I am inclined to 

 believe that it is distinct from S. vulgare. 



Scalpellum papillosum. King. Zoolog. Journal, vol. v, p. 334. 



Captain King has described this species, taken from 

 the depth of 48 fathoms, on the coast of Patagonia, in 

 Lat. 44° 30' S. It is probably distinct, but is so im- 

 perfectly described, that not even the number of the 

 valves is given. 



Polylepas (Pollicipes), Sinensis. Chenu. Must. Conchy liolog., 



PI. U, fig. 7. 



This species is said to come from China ; it is nearest 

 to P. sjjinosus, but is, I think, distinct.
