158 llev.T.Wmcks's Catalogue of Zoophi/tes 



The sporosacs are borne on polypoid supports (blastostyles), 

 which are clustered about the lower part of the body, and exhibit 

 what seem to be three or four rudimentary tentacles at the top. 

 The base of the polype gives off a few radical prolongations, by 

 which it is attached. Dr. Strethill Wright, I am informed by 

 Mr. Alder, is inclined to believe that Myriothela possesses a 

 polypary. I have little doubt that this is the case, as I have 

 noticed an appearance as of some horn-coloured substance in- 

 vesting the base of the body. 



5. Clavatella, Hincks, 

 C. prolifera, Hincks, Ann. & Mag. Nat. Hist, for Feb. 1861. 



In the smaller rock-basins, between tide-marks, Torquay; 

 not uncommon. 



I find in my note-book a rough sketch of a polype obtained at 

 Whitby, Yorkshire, in 1858, which I have little doubt was the 

 Clavatella. 



6. CoRYNE, Gaertner. 



1. C. ramosa, Ehrenberg. Johnston, Brit. Zooph. pi. 6. figs. 4-7. 

 Syn. Syncoryna Listerii, Van Beneden, 



In rock-pools between tide-marks; very common all along 

 the west coast. 



This species is a characteristic South-Devon form. Its fa- 

 vourite habitat is amongst the luxuriant vegetation which clothes 

 the sides of the tide-pools, where it attains a great size, and, 

 when laden with its rose-coloured gonophores, adds not a little 

 to the beauty of their scenery. I have a specimen from Torbay 

 which is nearly 4 inches in height. 



2. C. fruticosa, n. sp. Plate VI. figs. 5, 6. 



Polypary delicate, strongly annulated throughout, of a bright 

 horn-colour, much branched; branches ringed throughout, 

 constricted at their origin and widening upward, giving off 

 short ramuli, and commonly folding together on one side of the 

 stem, so as to present a somewhat secund appearance. Polypes 

 elongate, swollen below, tapering and pointed above ; tenta- 

 cles not numerous, short, capitate extremities small, a verticil 

 of about five immediately below the mouth, the rest scattered. 

 Gonophores densely clustered chiefly about the lower part of 

 the body, sessile, non-medusiferous, very large when mature. 



This species, which only attains a height of less than half an 

 inch, forms dense, clustered, bushy masses on Fucus. It is of 

 very delicate habit, its stems being only about half the thickness 

 of those of C. ramosa. Its polypes differ widely from those of
