to which they appear to me to bear no resemblance ; and in the 

 opinion which I here express Mr. Gr. S. Brady now entirely 

 coincides. I propose therefore to restore to the recent form, 

 which has been found on this coast, and in the Norwegian and 

 Arctic seas, the name C. Bradii, which I had previously proposed 

 for it. Judging from the figures and description in the Mono- 

 graph of the Tertiary Entomostraca of England, C. Bradii (Nor- 

 man), would seem to approach very closely to C. pinguis, Jones, 

 and is chiefly distinguishable from that species by the absence of 

 angulation of the dorsal margin. It was C. pinguis which I had 

 in my thoughts when I inserted C. Bradii — without a name — in 

 the dredging report of 1862, as a Cythere "new to science, if it 

 be not identical with a Tertiary Fossil species." 



Report on the Pelagic Entomostraca, by George S. Brady. 



During the dredging expeditions of 1863 and 1864 the sea 

 was mostly too rough to allow of the towing-net being used suc- 

 cessfully. In 1862, owing to the generally smoother sea, it was 

 worked to more advantage ; but as the dredges occupied almost 

 the entire attention of the party, the captures which we have to 

 record must be looked upon as embracing only the commoner 

 species of our free-swimming Oceanic Entomostraca. The gather- 

 ings of 1862 were made at a distance of fifty to one hundred 

 miles from shore nearly due east of Tynemouth. Those of the 

 following year were taken in the Holy Island district, and on the 

 Durham coast, three or four miles off Eyhope. The total number 

 of species taken was eleven, five of which are new to the British 

 Fauna, and two others have been hitherto only very imperfectly 

 recognized and described. Two out of the eleven belong to the 

 order Cladocera, the remaining nine to the Copepoda. The two 

 Cladocera belong to the family Polyphemidce, the nine Copepods 

 are distributed amongst the families Harpactid® (one), Peltididce 

 (one), CalanidcB (six), Pontellidce (one). 



I have described and figured in this report all the new or 

 imperfectly known species excepting Thalestris longimana and
