REPORT ON PHILIPPINE HYDROIDA 235 



by Kirchenpauer, Allman, Ritchie, and the present writer. It there- 

 fore seems proper to adopt the opinion of Ritchie and regard the 

 species of Linnaeus, Kirchenpauer, Allman, and Ritchie as identical, 

 and to these should be added my own L. hawaiensis with the type of 

 which I have compared the specimen under consideration. All of 

 these show a gonosome of peculiar type consisting of curved phylac- 

 togonia, beset with a double row of opposite nematophores. The 

 gonangia are ovoid sacs borne at the bases of the phylactogonia.
