is much smaller and is made up of a short basal portion, from 

 which springs a long, gradually attenuated apical joint. From 

 the basal joint there is given off on one side a long seta. The 

 terminal spines of the swimming feet (plate I, fig. 14) are pecu- 

 liar ; for instead of having one or more small supplementary spines 

 at the base connected with the first joint of the foot by a move- 

 able joint, as is usually the case, the spine is in this species 

 formed by a mere arched and pointed prolongation of the outer 

 edge of the foot. 



D. longiremis seems to be one of the commonest and most 

 widely distributed of our native Calanidse. It occurs abundantly 

 in a gathering taken off the Durham coast; also at the Pern 

 Islands, and in the open sea one hundred miles off Tynemouth. 

 Mr. Norman has taken it at Rothesay, Mr. Lubbock at Weymouth, 

 and I have myself found it amongst the Channel Islands, in the 

 Isle of Man, in tidal pools on the Durham coast, and in pools of 

 brackish water on Burgh Marsh, near Carlisle. The specimens 

 taken in the last-named locality are, however, stunted and ill- 

 developed, being only about sVth of an inch in length, the result, 

 I suppose, of an uncongenial habitat.
