COLLECTED IN TORRES STRAITS. 447 



" These Algae were fouiid at Somerset, at low-tide mark ; dredged 

 ac Cape York in 5-8 fathoms, and off Wednesday Island, Torres 

 Straits. From these three localities the specimens were unfortu- 

 nately mixed. The places, however, are close together ; and there 

 seemed little difference in the flora."
