Monogr. des Oscill. 76. p/. 72. f. 8-10. This species was abundant 
at Goose Creek, Cape Rosier; Maine, in July of 1893 and of 1895, 
forming a rather thick, black, slimy coating on dead sticks 
Zostera, etc. 
AMPHITHRIX JANTHINA (Mont.) Bornet & Flahault. This occurs 
at Rockport, Mass., on wet cliffs just above high water mark; 
and var. TORULOSA (Grun.) B. & F. grows in abundance in the 
autumn months on stones ina ditch in the salt marshes at Re- 
vere, Mass. Though described by Bornet and Flahault as a fresh- 
water plant, at this last station it grows in company with brackish 
and marine species like Polystphonia subtilissima and LEctocarpus 
confervoides.

_ In Farlow’s Manual of the Marine Algae of New England, Le 
Jolis is followed in including the species of Exteromorpha in the 
genus U/va, and considering most of our forms as subspecies or 
varieties. Subsequent study by Agardh, Ahlner, Reinbold and 
others has tended to considerably change this arrangement, and it 
is now generally recognized that Enxteromorpha should be con- 
sidered as a distinct genus, represented by quite a number of 
species in this region. £. compressa (L.) Grev., &. intestinalis 
Link, £. clathrata (Roth) J. Ag., E. Hopkirkii Harv. and £. ramu- 
losa (Engl. Bot.) Hook., which appear as synonyms in the manual, 
are now accepted as specific names, as is also 4. marginata J. Ag., 
which was recorded in the BuLLeTIN for December, 1884, under 
the name of Ulva marginata. E. micrococca Kiitz was mentioned 
by the writer in the Buttetin for November, 1891, and &. erecta 
in J. Agardh, Till Alg. Syst. 3: 152. 
To these can now be added the following : 
E. PROLIFERA (Fl, Dan.) J. Ag., a species resembling in habit 
£. compressa, from which it is distinguished by having the cells 
arranged in longitudinal series almost throught It Appears: 
to be common all along the coast. 
_ E. crivita (Roth) J. Ag. This species r resembles &. clathrate
