more especially in its bearing medusoids, These latter spring 
from the encrusting base. No capsule could be detected, but 
this might possibly arise from its great transparency. The 
medusoids bear a great resemblance to those of Podocoryne 
carnea, Sars, the only difference being in their having eight in- 
termediate tubercular tentacles. In this respect they also differ 
from the medusoid of a Hydroid Polype, described by Professor 
Lovén, and referred by him to Hydractinia, but which appears 
rather to belong to the genus Podocoryne, as the base was not 
horny or spinous. As far as I am aware, therefore, this is the 
only instance in which medusoids have been ascertained to be 
produced by a true Hydractinia.

Hodge, in Trans. Tynes. Club, v. v., p. 82, t. ii., 
f. 10—15. 
On a Serpula from deep water, Seaham Harbour.—WMr. 
Geo. Hodge. 
This species differs from the P. carnea of Sars, principally in 
the form of the medusoid, which somewhat resembles that of an 
Atractylis.

p. 102. 
Coryne eximia, Allm. in Ann. Nat. Hist., 3rd ser., 
vy. iv., p. 141. 
At the time of the publication of our local Catalogue of 
Zoophytes, the British species of Coryne were very imperfectly 
understood, but they have since been more carefully investigated, 
and several new species have been described. Among these is 
the one now under consideration, which I had referred to the 
Syncoryne Listerii of Van Beneden. Specimens kindly sent me 
by Professor Van Beneden, however, prove his species to be 
synonymous with the Coryne ramosa of English authors. I
