THE lobster's-horn. 313 



and when I returned in two or three hours, the ani- 

 malcule was a mere loose mass of granules, as were 

 those which were as yet confined in the parent vesicle- 

 I presume therefore that the quantity of water which 

 I had allowed to the specimen (a large drop in the 

 live-box of the microscope), was not sufficient to sup-

 thus formidably bristling with hairy horns. I am not 

 quite sure, however, whether the Zoophytes were 

 growing there, though many of them were furnished 

 with their slender waving root-fibres, and stood erect. 

 As stones in sand, and the sand itself are mentioned 

 as the localities affected by the species, it is probable 

 that the Spider- Crab, having casually been roving over 

 aforestof the stems, had got many of them entangled

 specimens were fragments of stalks, evidently so

The Anten7iularia has an aspect very diverse from 

 the Sertulai'ice, Tliimularim^ and Campanularice, with 

 which it is allied, in its more robust form, its deep -
