ADDENDA TO REVISION OF PODOPHTHALMATA. 
By A. O. Waker, F.L.S. 
The following species were either accidentally omitted 
from the “‘ Revision,” or were found this Summer shortly 
after the volume had been issued. 
Pinnotheres veterwm, Bosc. 
One male and two females from the branchial sacs of 
small specimens of Ascidia mentula, measuring about 
1} inches in greatest length; dredged off Clay Head, 
Isle of Man, 12 fath., Sept. 24th, 1892. 
Prof. Herdman informs me that the branchial sac 
was almost completely filled transversely by the 
Punnotheres which could not possibly have got either 
in or out of the Ascidian at anything lke their present 
size.
