THE Entomostraca recorded here were collected by William 
S. Bruce, in June and July 1898, while cruising in the Arctic 
Seas with Mr. Andrew Coats in his steam yacht the 
‘ Blencathra.’ These micro-crustracea consisted chiefly of 
Copepoda; some Ostracoda were obtained, but they com- 
prised only a few moderately common species, while the 
Cladocera were represented by one or two examples of the 
ephippia of Daphnia sp. 
The Copepoda number 59 species in all, and they belong 
to the following nine families, viz.:—to the Calanide, 4 
species ; the Centropagide, 3 species; the Pseudocyclopide, 
1 species; the Pontellide, 2 species; the Cyclopide, 4 
species ; the Harpacticide, 40 species ; the Lichomolgida, 
1 species; and the Asterocheride, 4 species. It will be 
observed that the largest number of species (40) belong to 
the Harpacticide ; most of them, however, are represented by 
only a few specimens. On the other hand, the species in the 
collection represented by the largest number of specimens
