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. 
Occurrence.— Upper Jacksonian (Ocala limestone) : Ocala, Florida (rare) ; 
Bainbridge, Georgia (rare). 
Geological distrib'ution . — Helvetian of Egypt and France (Canu) ; Zanclean 
of Italy (Seguenza) ; Plaisancian of Italy (Manzoni, Neviani) ; Sicilian of Italy 
(Seguenza, Neviani); Quaternary of Italy (Neviani).

ranean, France, Italy, and the Adriatic; Pacific, Australia, California; Indian

The species inhabits the region of the laminarian seaweeds. It seldom lives 
at a depth greater than 30 meters.

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.

North Carolina (rare).
