one of them retained an entire zooecium which seemed to us to agree exactly with 

 the figure of the species given by Waters in 1913 in his work on the Marine Fauna 

 of British East Africa and Zanzibar. Unfortunately, in cleaning the specimen a 

 stroke of the brush destroyed it. leaving our determination doubtful.

The figure on plate 32 represents a specimen from Wilmington, North Carolina, 

 which in the thinness of its stolons is quite similar to Aetea truncata Landsborough. 

 1852. However, it is impossible to make a definite determination without an entire 

 zooecium.
