distinguished by the peculiar arrangement of its extreme 

 ramifications. The ultimate ramuli are set on the 

 inner edges of the terminal branchlets, exactly like 

 the teeth of a comb, three or four little awl-shaped 

 teeth in a row upon each branchlet, and the branch- 

 lets themselves, set in the same way, upon the edges 

 of the penaltinate branches. 



It adheres very well to paper when mounted fresh 

 from the sea, under considerable pressure. It is so 

 common at all seasons, along the whole western coast, 

 that particular localities need not be named. 



It is not a little sin^lar, that this species, which 

 is so common on the western shores of both Europe 

 and America, should not be found at all on the 

 eastern coast of America, lying directly between.

The same remark may be made of this as of the 

 last species ; the singularity of its occurrence on the 

 western shores of both continents, and its absence from 

 •the intervening east coast of America. 



* Steno.^ramma interrupta =: An interrupted mark or line.
