90 NATURAL HISTORY OF 



soid phase, but Dr. Wright reared the polypites from 

 the ova, and by that means was enabled to identify and 

 describe the species. The stem of the trophosome is 

 simple, sometimes ringed throughout. The calycle 

 has 8 or 9 denticles. Described in Forbes^ " Mono- 

 graph of British Naked-eyed Medusae," 52, and by Dr. 

 Wright in the Journal of Micr. Science (N.S.), ii. 221 

 and 308. 



Genus VI. Gonothyr^Aj All. {'y6vo<i, offspring,

Stem erect and braached, rooted by a thread-like 

 stolon. Cahjcles campanulate and hyaline. Polypites 

 with a prominent contractile proboscis. Reproduction 

 by fixed medusiform sporosacs, furnished with a circle 

 of filiform tentacles. — T. H.

Ellis accurately figures this species {" Corallines," 

 pi. xii. C, and xxxviii. B), but identifies it with his 

 " Sea-thread Coralline," the remaining figures of which 

 (pi. xii., figs, a, A) refer to 0. dichotoma. 



This species grows in bushy tufts, and somewhat 

 resembles G. Jiexuosa in appearance. The calycles are 

 alternate with indented margins (10 teeth), and borne 

 on ringed pedicels.
