4, Note on an Ectoparasite of the Menobranch.

[Received June 24, 1886.] 
The specimens of Menobranchus recently brought by me from 
Toronto and presented to the Society’s Collection were infested 
by an ectoparasitic Trematode, Sphyranuria osleri, mihi, which I 
first described in the ‘ Proceedings of the Canadian Institute,’ 
Toronto, 1878. The preserved specimens on which I founded my 
description enabled me to determine the zoological position of this 
parasite, which turned out to be an interesting form intermediate 
between Gyrodactylus and Polystomum ; but I was obliged to postpone 
any closer investigation into its anatomy till I had access to fresh 
specimens. I have recently had abundant opportunity of securing 
these, and I propose shortly to publish elsewhere the results of my 
studies. 
In view of the interest attaching to a certain parallelism between 
the phylogeny of the Polystomide and that of their hosts, I take the 
present opportunity of referring to the desirability of examining any 
Urodela which may die in the Reptile House, in case of possible 
additions to this interesting family of Trematoda. 
5. Descriptions of some new Species of Rhopalocera from 
the Solomon Islands. By Grervase F. Maruew, Staff-

During nearly a four years’ Commission on the Australian Station, 
H.M.S. ‘Espiégle’? was employed for a greater part of her time 
among the islands of the Western Pacific, and, upon two occasions, 
paid brief visits to the Solomon Islands. _ It is to be regretted that 
she did not prolong her stay at this charming group, for, from the 
little seen of them, they appeared to be, entomologically speaking, a 
perfect paradise, being clothed from water’s edge to mountain’s peak 
with the most luxuriant and varied tropical vegetation. 
But a serious drawback to collecting was the hostility and 
treachery of the natives. At many places they were cannibals, and 
extreme caution had to be exercised when landing—indeed at some 
places collecting was quite out of the question, as it would have been 
almost certain death to have ventured into the forest alone. When 
the natives have had more intercourse with white men it is to be 
hoped that they will become more civilized, and discontinue their, at 
present, unpleasant customs. Now they look upon all white men
