LVIJ.—Notes on Sunaristes paguri, Hesse, and some other rare 
Crustacea. By Tuomas Scort, F.L.S., Naturalist to the 
Fishery Board for Scotland, and ANDREW Scort, Fisheries 
Assistant, University College, Liverpool. 
[Plates XI, & XII.] 
In 1893 we described * under the name of Canuella perplexa 
an apparently new Copepod that had been observed in the 
Firth of Forth. In our description of this Copepod we 
referred toa certainsimilarity between it and Sunaristes pagurt, 
Hesse—a species that M. Hesse had discovered living as a 
parasite on a Pagurus sp. (now Lupagurus). Weat the same 
time pointed out some differences which we considered 
warranted us in describing the Copepod from the Firth of 
Forth under a new generic name. 
We had not at that time seen specimens of Sunaristes, but 
had been guided in our decision by the description and figures 
of the parasite published by M. Hesse, supplemented by those 
of Herr W. Miller, who, subsequent to, but evidently unaware 
of, M. Hesse’s discovery, had, under the name of Longi- 
pedina paguri, also figured and described this crustacean, 
Having been successful during the past year or two in 
_ obtaining several British specimens of Suwnaristes, both male 
and female, we have by an examination of these been enabled 
to prepare the following notes and drawings, showing the
