The genus Siphonactinia* is also very closely allied to this. .S^. 

 Boeckii, its type, is very much like the present species in form and 

 structure. 



Gorgonia (Leptogorgia) tenuis Verrill. 



The localities for this species are still imperfectly known. A fine 

 specimen in the Yale College Museum is supposed to have come from 

 Long Island Sound.

This species occurs at low water among eel-grass (Zostera) on 

 sandy shores, from Dartmouth, Mass., to Beaufort, N. C. Mr. Say 

 indicates a species, probably the same, from Cape May. It has not 

 been observed north of Cape Cod.

 Say's specimen was from Cape May, collected by Mr. J. Eobbins. 

 I am not aware of any other being found.

§ There appears to be no good reason for rejecting the Linnean name, Asterias, 

 for this genus with A. rubens Linn, as the type. Anteraranthion Miillcr & Troschel is 

 synonymous with Asterias as restricted and adopted by Cray, and by Dr. Stinip- 

 son, and many others. The use of Asterias in botany, anterior to its employment 

 by LinnjEUS, alluded to by Dr. Liitken (Gronlauds Echinoderms, p. 28) should not
