BRITISH ZOOPHYTES. 43 



boscis white. Tentacles 4 — 30. Gonophores borne in 

 clusters on the body of the polyp some distance below 

 the tentacles. 



Mr. Hincks has clearly made out the presence in 

 this species of spiral and tentaculoid appendages, 

 similar to those which are so prominent a feature of 

 the preceding species (A. and M. of N. H., February, 

 1877, 150). It is curious also to notice that the shells 

 upon which this species and H. echinata establish 

 themselves are usually occupied by hermit crabs. 



, 2. P. AREOLATA, Aid. 



Hydractinia areolata {Aid.) , Rhizoclina areolata {All.). 



Hab. : Cullercoats (Aid.), Shetland {A. M. N.), 

 Seaham Harbour {Hodge). Height ^ in. Polypites

 linear spines in irregular groups." Gonophores sessile, 

 borne on the stolon and not on the polypites. 



3. P. PROBOSCIDEA, T. H. 



Hab. : Ilfracombe {T. H.). Polypite orange-brown, 

 tall and rather stout, having a long columnar proboscis 

 of opaque white colour. Tentacles about 14. Gono- 

 phores " forming a large collar round the polypite, 

 a short distance below the tentacles, borne in two rows 

 on small tubercles." 



First described by Mr. Hincks in the appendix to 

 " British Hydroid Zoophytes," p. 317. 



Genus II. Corynopsis, Allman. {Kopvvri, a club, and
