212 SEA MOSSES, 



CCRAMIUM DeSLONOCHA^m ... (. H. 



This species Harvey describes as C. I/oopcn, m 

 honor of his friend, Mr. J. Hooper, of Hrooklyn, 

 N. Y., an enlhusiasiic and intelligent A 

 who with Professor IJailey and others, as I hive 

 already mentioned in the " Inirodction," did much 

 in that time, to help forward Har\'ey*s study of our 

 plants. They all find ample acknowledgement in 

 the pages of the " Nereis." 



But it is conceded now that *^ '•^ is no new 

 species, but an old and not uncumnion one, f^n 

 the shores of Europe. It is common along our 

 northern coast, north of Nahanl. I f :nd it in 

 plenty at Marblehead, and Mr. Collins at Nahant 

 on the sides of perpendicular rocks, overhung v.iili 

 Fyd. Mrs. Davis collects it on rocks in tide ] 

 at Gloucester. Professor Vcrrill found it on tlu- 

 piles of the mh\" I'l^itport, and Mr. I*rudden ai 



Grand Manan. ^ ^ from two to four or five 



inches high, from a m^xsA of creeping filaments. 

 The fronds are not much coarser than human hair, 

 and divide throughout by true but not very wide, 

 forkings. The apices are attenuated, shari)ly pointed, 

 and but slightly incurved or bent, mostly straight 

 or awl- shaped.
