48 BRITISH HYDROID ZOOPHYTES. 



Garveia nutans, Wright. 



3 specimens in liquid. 



specimens The Hastings specimens are 

 13, 14, 15. found creeping up the stems and 

 branches of other hydroids, such as 

 Hydrallmania, throwing up simple stems 

 with polypites and ccenosarc of a carrot pink 

 colour, which readily catch the eye. The 

 polypites are club-shaped. The tentacles 

 number about twelve, and are in a single 

 circle. The polypary is transparent and 

 faintly ringed, and is expanded trumpet-wise, 

 conformably with the polypites. The gono- 

 phores are round or oval, of an orange colour, 

 and emerge from a slightly expanded polypary. 

 The specimens were trawled off-shore, also 

 from deeper water, and are somewhat rare. 

 There are slight differences between the 

 Hastings specimens, and those described and 

 figured by Hincks, not, however, sufficient to 

 warrant a fresh specific description, the main 

 point of difference being, that in the present 

 examples they are parasitic, and consequently 

 do not require to form a strong compound 

 stem.
