 North shore, (Gould.) A species which Mr. Wheatley identifies with 

 this was dredged in abundance in 8 to 13 fathoms, among Cladophora^ 

 on the south side of Saint Ignace Island. These specimens are, however, 

 much less elongated than the figures of L. lanceata ; approaching, it 

 seems to me, much more nearly to L. desidiosa.
