in England, France and Switzerland as occurring in en- 

 tirely fresh waters. The above review of the known 

 species and their distribution does not do justice to Stret- 

 hill "Wright's careful description of the animals that 

 make the cases or bottles on the British coasts where he 

 found species not entirely synonymous with the above- 

 cited ten. 



The first record of the occurrence of any of these bottle 

 animalcules along the American coasts seems to have 

 been that of Leidy, who, in July, 1859, at Newport, Rhode 

 Island, found attached to Anomia-serpula on dead clam 

 shells dredged by Mr. Powel a singular and beautiful 

 animal " in a vase-like tube and with the same general 

 structural appearance as that of the stentors. 



He recognized its resemblance to Chcetospira mueleri 

 Lachman and its alliance with the stentors and suggested 

 the name Freyia Americana for it. Later, according to 

 Ryder, Leidy considered his species to be the same as the 

 European Folliculina ampulla. It was not till 1880 that 

 the bottle animalcule was again observed in American 

 waters, and then Ryder on the western shore of the Ches- 

 apeake Bay, probably at St. Jerome, St. Mary's County, 

 found a different form of bottle and animal which he 

 identified w^ith the Freia producta of Strethill Wright. 



The occurrence of this form of bottle animalcule in 

 other parts of the estuaries of the Chesapeake w^as 

 pointed out in 1914, 1915 by Andrews under the name 

 Folliculina, but without determination of the species de- 

 scribed. Meantime it was known to workers at Woods 

 Hole, Mass., that Folliculina occurred there also, though 

 no published accounts appeared. Dons has recently 

 mentioned the observation of a Folliculina upon material 

 from the east coast of America and refers another species 

 to this coast, probably from the above account of Leidy.
