FKESn-WAXER CYCLOPIDJ*; AJfD CALAJflDiE. 87 



This species occurs in a gathering made by the Rev. Dr. 

 Norman in the River Till at Etal, Northumberland, and Mr. 

 Scourficld records it from Wanstead Park, Essex, and from the 

 River Lea at Tottenham. Mr. Thomas Scott has also recently 

 sent me specimens from Raith Lake, Kirkcaldy, Pifeshire, and 

 Dr. Norman others from Yetholm Loch, Roxburghshire; the 

 previously recorded British localities being Peterhead, N.B., and 

 Pwllheli, North Wales. Professor G. 0. Sars found it near 

 Christiania.

Female, — Anterior antennse about as long as the cephalothorax, 

 eleven-] ointed ; the first, seventh, and eleventh joints nearly 

 equal and longer than any of the rest; second and fifth joints 

 very short. The four pairs of swimming feet have both branches 

 three-jointed ; fifth pair of feet two-jointed, the basal joint bear- 

 ing a single long seta at the inner angle, the last joint one long 

 and one very short seta at the apex. Last thoracic segment 

 narrower than the preceding one, dilated behind, and equal in 

 width to the first abdominal segment, from which it is not sepa- 

 rated by any distinct constriction. The first abdominal segment 

 has at each side two small lateral setse, one of which is spine- 

 like. Caudal rami not divergent, in length rather more than 

 equal to the two preceding segments ; the longest tail-seta equal 

 in length to th§ entire abdomen. Length 1-4 mm. 



A considerable number of specimens of this species were taken 

 by Mr. T. Scott, in November, 1887, in the tow-net in a small 

 bay west of Charleston, about five miles above Queensferry, 

 Firth of Forth. It is interesting as being the only undoubted 

 member of the genus which has been found living in the sea. 

 But the Forth at this point is subject to considerable admixture 

 of fresh water, and it is possible that this Cyclops may have its 

 real habitat in some of the streams or ponds whose contents find 

 their way into the Forth. This is a matter to be decided by 

 future investigation.
