MICROSCOPIC OBJECTS. 55 



Fig. 109. A Zoophyte (Laomedea gelatinosa), x 20. 



This is one of our commonest Zoophytes,, the specimen from 

 which the drawing was made having been collected at Hastings. 

 The zoophyte is found at low tide in the rock-pools opposite 

 Eversfield Place, and at many other places along the seaside. 

 The animal will be distinguished by its plumose appearance 

 when growing on the marine Algae, or on stones, which 

 form its favourite habitat. The description of the species is, 

 " Polypidom rooted, erect, jointed at regular intervals ; joints 

 ringed ; cells alternate, on short peduncles, campanulate ; 

 vesicles axillary, &c." The zoophyte is best when killed 

 immediately by immersion in alcohol, and then mounted in 

 alcohol and water, or in camphor-water. 



Fig. 110. A Zoophyte (Plumularia setacea), x 20. 



This Zoophyte, like the preceding species, is commonly 

 found on our coasts, more especially the south and south-east 

 coasts. It will often be found growing in great abundance, 

 even more so than the last species, on the underside of rocks 

 &c., and is nearly always found near, if not growing with, 

 Laomedea gelatinosa. The description of the animal is, 

 " Stem a single tube, pinnate ; pinnse alternate, one at each 

 joint ; cells very remote, campanulate ; vesicles elliptical." 

 The animal may be killed by immersion in alcohol, as men- 

 tioned with respect to Laomedea. It may also be mounted in 

 the same manner.
