for the rarer species will be found in the List of Irish Polyzoa 
which is in preparation. 
The following species call for somewhat more special notice :— 
Bicellaria Alderi, Busk. 
This rare form was found growing on Flustra Barleei, Busk, 
from Station 114, off the Skelligs, at a depth of 80 fathoms. Only 
a small portion was obtained, but it exhibits all the distinctive 
features of the species. As usual in British examples, contrasted 
with Scandinavian, the avicularia were absent. Like the Flustra 
on which it was growing, this is the first time it has been recorded 
for Ireland, and it has only previously been found in British 
waters from the Shetlands by Mr. Barlee and Canon Norman. 
Flustra Barleei, Busk. 
A large colony, nearly 2 inches in height, was trawled from 
off the Skelligs, along with the previous species. In the large 
unarmed rectangular cells and oblique position of the avicularia it 
is easily distinguished from the other more common F lustras. The 
immersed. ovicells are well shown in this Irish specimen. The 
species has only previously been obtained from British waters by 
Mr. Barlee, from Shetland, and “between Whalsey and Balta, 
and off Unst,” by Canon Norman. The present occurrence con- 
siderably extends its southern range. 
Triticella Boeckii, G. O. Sars. 
This species, previously only known from Christiania Sound, 
was first recorded by me (/. c., p. 131) for British seas, as having 
been obtained by the Royal Irish Academy Survey from Bere- 
haven, growing on Portunus depurator. On two or three different 
occasions the Royal Dublin Society’s Survey trawled it in Kenmare - 
River, in each case growing on Gronoplax angulata. Only a few 
individuals were present on one specimen, as the crustacean ap- 
peared to have lately shed its shell. Another Gonoplax was almost 
covered with large scattered clusters, they being especially abun- 
dant on the antennz. Both the peduncles and zocecia are very 
variable in size according to their position in a dense cluster. ‘The 
more central ones are much longer, and quite overtop the others. A 
third Gonoplax had its shell also partially coated with the Polyzoan.
