Hersilia (Clausidium) vancouverensis, sp. n. 



In the summer of 1911 Mr. F, A. Potts, of Trinity Hall, 

 Cambridge, collected a large number of specimens of 

 Callianassa pugettensis from a stretch of sandy beach at 

 Hammond Bay, near Nanaimo, Vancouver Island. A small 

 copepod occurred in vast numbers in the gill-chambers and 

 also all over the body of many of the Callianassa, conspicuous 

 on account of the bright red colour of the egg-sacs. They 

 alternated betvreen a state of quiescence, during which they 

 were attached to the surface of the host, and rapid jerky 

 movements, made when disturbed. The tiny male was 

 attached to the tail of the female in almost every case. 



On liis return home Mr. Potts gave me the copepod for 

 identification, and I found that it belonged to the genus 

 Hei'siha,
