Stn. 15 A.A., Sept. 8, 1899, Lat. N. i' 35', Long. W. L36' 54', surface temp. 

 79'. A single young specimen of the solitary generation was collected 

 on the surface. 



Salpa democratica-mucronata Forsk. 



This species was taken at two stations, both off the coast of Southern 

 California.

 temp. 59". A number of both generations was collected. The solitary 

 generation has very long, slender processes at the posterior end. In some cases 

 these processes are almost as long as the body. In tliis particular they ap-

 the two.

 at station 2928. 



Salpa fvisiformis-runcinata Cuv.-CnAM.

 both generations were taken at different stations from the coast of Alaska 

 to the South Pacific.
