ZOOPHYTES.

(a) hydrothecas on simple stalks of variable length, viz. from 
three to nine rings; and ( b ) branched stems of some height, 
with the alternate stalks of the hydrothecas composed of from 
six to more than a dozen rings. Moreover, in these branched 
forms it is not uncommon to see more than one pedicel arise 
at the same fork, so as to cause the observer to fancy he is 
viewing the Campanulina turrita of Prof. Wyville Thomson ; 
only the hydrothecas are much shorter in proportion to the 
length of the teeth. Some examples on a laminarian stalk 
had very long stems. The hydrothecas in all very closely 
resembled those on Dr. Allman’s Campanulina repens (Hincks, 
Brit. H. Z. vol. i. p. 189, pi. xxxviii. fig. 1). No gonothecas 
were observed. 
Fam. 4. Lafoeidse. 
Genus Lafoea, Lamouroux. 
Lafoea dumosa , Fleming ; Hincks, Brit. H. Z. vol. i. p. 200. 
Common on various zoophytes from deep water. Some 
varieties of this species have short stalks of one or two whorls 
supporting the hydrothecae ; but they are not quite so long as 
those described under L. fruticosa , Sars, and the intermediate 
forms show that they are to be referred to the present species. 
Lafoea fruticosa , Sars ; Hincks, Brit. H. Z. vol. i. p. 203. 
Occasionally on zoophytes from deep water, especially Ser- 
tularia filicula. The pedicels of the hydrothecae have from 
three to five rings. 
Besides the above there are several microscopic forms closely 
allied, which creep along the stems of various zoophytes. A 
sessile form is common on Crisia eburnea , and a stalked species 
on Scrupocellaria scruposa. 
Genus Calycella, Hincks. 
Calycella syringa , L.; Hincks, Brit. H. Z. vol. i. p. 206. 
Abundant on the stems of Hydrallmania falcata and other 
zoophytes from deep water.
