Genus Eurydice. 
E.pulchra, Leach. 
This pretty species has been taken at Larne by Mr. R. Patterson (1838), 
and at Carrickfergus, between tide-marks, by Mr. Hyndman (March and 
April). Bantham, Devon, the original locality (Leach, Linn. Trans., xi. 
370), appears to be the only one yet noticed for E . pulchra. 
Genus ^Ega. 
JE. bicarinata, Leach. 
March 30, 1839. I procured an individual of this species alive in Bel- 
fast market, whither it was brought with oysters from Carrickfergus. It 
was not known to Dr. Leach whence the specimen was brought that 
served for his description, and the works accessible to me in which the 
species is introduced do not contain any information as to its habitat. 
2E. tridens, Leach. 
North of Ireland. 
Genus Bopyrus. 
B. squillarum , Latr. 
A Palcemon serratus, taken by Dr. Ball at the South Islands of Arran, 
off the coast of Clare, in June, 1835, contained within the plates of the 
head a fine specimen of this Bopyrus, 6^- lines in length, and agreeing 
with the female as represented by Desmarest and other authors. 
B. hyppolytes, Kroyer. 
Two females of this species were found within the carapace of the Hip- 
polyte varians , Leach, which I obtained on the coast of Galway in July, 
1840. M. Kroyer found it on the Hippolyte polaris.
