REPORT ON PHILIPPINE HYDROIDA 203 



tion seems to me to refer to quite a different form. 8 Bale's descrip- 

 tion is as follows : " Hydrorhiza, slender, climbing, hydrothecae 

 borne on long peduncles which spring either directly from other 

 hydrorhiza or from the side of other peduncles; peduncles slender, 

 with about 8-16 rings at the base and a less number (mostly two 

 or three) at the summit, smooth throughout the rest of their length. 

 Hydrothecae large, campanulate, constricted at the 'floor' which 

 is raised above the base so as to inclose a nearly cylindrical cavity ; 

 margin, not expanding; armed with 10-14 rather large triangular- 

 pointed teeth. 



" This is a delicate species with no proper stem, but the primary 

 peduncles generally give origin to secondary ones exactly resembling 



them." 



Miss Thornely, on the contrary, says that her specimen "is 

 branched and has a straight compound stem formed by the down- 

 ward growth of the peduncles of the hydrothecae." 



As a matter of fact, this is a very common state of affairs as I 

 have already shown. 9

THYROSCYPHUS MARGINATUS (Bale) not Allman

 phytes, 1S84, p. 54.

 Only a fragmentary specimen was found in the Albatross mate- 

 rial. Fortunately, however, the peculiar squarish and four-toothed 

 margin with its double border makes it reasonably certain that we 

 have this species to deal with. After originally placing it in the 

 genus Campanularia, Bale, the describer, placed it in the genus 

 Thyroscyphus, a genus of Campanularidae, doubtless on account 

 of its operculum, which he mentions indeed in the original descrip- 

 tion of 1884. So far as the present writer can ascertain, this species 

 has hitherto been reported from Australian waters only, so that 

 the specimen secured by the Albatross affords the first record from 

 the Philippines. 



As this form has never been adequately described, the following 

 description is appended : 



The largest fragment secured by the Albatross is 4y 2 cm. in 

 height and the hydrorhiza is absent. The main stem is monosi-
