Lycoris viridis, 419 



of the genus Cypris, but every Cypris I have seen moves by articulated 

 limbs, and not by the assistance of a ciliated fringe. In these particles 

 no members of the kind could be detected, but as the magnifier I use is 

 one of no great power, some other observer, with a better glass, might 

 easily unfold their whole structure. 



Dr. Fleming describes the Polypes as having from 18 to 20 tentacula, 

 but I could discover 16 only, and the number appeared constant. The 

 animals are easily procured for examination by breaking down a portion 

 of the Polypidom in a little salt water. It is a very common species on 

 the coasts of North Durham and of Berwickshire, and is always found 

 attached to marine plants. It is frequent on the stem of the Laminaria 

 digitata, but more common on Ptilota plumosa and Delesseria coccinea. 

 When on the former it grows free, but it first encrusts the fronds of the 

 latter, and then throws out its leaf-like processes and expansions.

Desc. Body of a uniform grass-green colour, marked with darker 

 lines, slender, depressed, tapered towards the tail, which is terminated 

 by two filaments. Segments numerous, the first (exclusive of the head) 

 convex, smooth, and striated with longitudinal white lines. The feet 

 appear to be divided into four conical processes, from one of which is 

 exserted a brush of long black bristles. Length 4 inches. 



Obs. A green species of J^ereis has been admitted into the British 

 Fauna on the authority of Mr. Adams, of Pembroke. He has given no 

 description but that which is embraced in the very short specific character 

 of Linnaeus ; for the extended description, in some British works, is taken
