they are disposed in somewhat radiate fashion. This curious 
variety, deprived of its terminal expansions, bears a striking 
resemblance to the Solaster. In form and general appearance it 
is utterly unlike the ordinary 7. phalangea ; and yet, such is the 
tendency to irregularities of growth and habit in this section of 
the Cyclostomata, that I do not venture to regard it as more 
than a very singular illustration of this characteristic. 
In an early stage, JT. phalangea exhibits a simple bilobed 
form, and is often of very delicate texture and of a silvery lustre. 
In this condition the polyzoarium is stalked, and divided into 
two rounded lobes, which are bent backwards from the point of 
division, so as to embrace the stalk, below which they finally 
coalesce. As growth proceeds, other lobes are developed on the 
opposite side, until the normal figure is completed. 
4. T. flabellaris, Fabricius. 
Rare: in a valve of Pecten, from the Brixham trawl-boats ; 
on stone. 
One or two specimens only have occurred to me in the West 
of the species figured by Johnston (pl. 46. figs. 5, 6), and which 
he identifies with the Tudipora flabellaris of Fabricius.

5. T. penicillata, Johnston. 
On the Cornish Pinne, common ; on stone from 40 fathoms ; 
in a shell from Torbay. 
In this species, the erect portion, which bears the expanded 
celluliferous head, springs from a creeping Alecto-like base, 
which is thickly set with tubes. This creeping stem is com- 
monly branched, and at the extremity of each branch rises one 
of the disk-bearing stalks. The lower portion of the stalk 
frequently bears a number of the tubular cells on one side, 
which are free, and of considerable length, There is great di- 
versity in the height of the peduncular support and in the size 
of the terminal disk. Mr. Couch, in his description, takes no 
notice of the creeping base. Should not the genus Alecto be 
modified so as to include both this species and the Pustulopora 
deflexa of Johnston ?
