These alge have been found especially north and southwest of Pivers Island, on the 
laboratory jetties and along the town front, apparently because these localities had more 
places suitable for attachment. 
Records for other localities in this region have been obtained only for the summer. 
During this season algz are scarce in the harbor beyond the vicinity of the laboratory. 
Along the shores of the marshes north of Pivers Island and north of Morehead City there 
have been found only four species, as follows: 
Ulva lactuca var. latissima. 
Fucus vesiculosus. 
Gracilaria confervoides. 
Hypnea musciformis. 
No alge were found in the water extending into the marshes. This water is very 
muddy, is scarcely affected by ordinary tides, and frequently is very hot. 
@ Found growing only on buoys.
