Notes on New England Marine Algae.—VI. 
By Frank S. COLutins. 
The species mentioned in the following notes have not, as far oe 
as I know, been recorded from our coast, except that Radfsia pusilla — : .g 
and Desmotrichum undulatum were mentioned in the Flora of io 
Mount Desert by Rand & Redfield, and Entophysalis granulosain 
my list of the algae of Atlantic City, N. J., Butterin, December 
1888. Unless otherwise noted, the specimens were collected by 
me. 
ENTOPHYSALIS GRANULOSA Kurz. This species I have found at 
Cape Rosier, Maine; Mr. Isaac Holden finds it at Stratford, 
Conn.; and it occurs at Atlantic City, N. J.; probably it is com- 
- mon all along the coast. It forms a crumbly incrustation at high- _ . 
water mark, and seems to prefer lagoons or high tide-pools, where _ 
the water is quite salt and where the level does not vary much. _ 
It is figured and described in Bornet & Thuret, Notes Algologi- 
ques, I. pl. x. fig. 4 and 5, and distributed in Collins, Holden & 
__ Setchell, Phyc. Bor. Am. no. 152. | ; 
_ SprrutinA MenecHiniaNA Zan. Found in wieon, 1893, in 
, the salt marshes at Revere, Mass., in scattered — filaments : 
among other algae in a ditch of brackish water. It has a much : 
looser spiral than S. sudsalsa Ocrsted (S. tenuissima of Farlow’ 
-Manval). Figured and described in = Gomnont, Monogr. des Osc 
270. pl. 7. fig. 28. 2 ae .
