Endoproct

Nickerson (1898) added a single species of endoproct (Loxosoma davenporti) to our local fauna, this being first described from specimens taken by him at Cotuit Harbor.

The three families of endoproct (Pedicellinidae, Urnatellidae and Loxosomatidae) can be distinguished by the form of the zooids and the growth habit.

Leidy (1870) noted that he found the hydroid when searching in the Schuylkill River at Fairmount, Philadelphia, for Urnatella and seems to suggest that Cordylophora was living where experience had shown the endoproct in the past had been likely to occur.
