Large numbers of this species were found creeping over the tufts 

 of Cladophorse in tide-pools on the north-west side of Cawsand Bay, 

 March 26th, 1890, and on the same green weeds in pools near high- 

 water mark south of the bathing pond in the middle of April, In 

 these latter pools I could not discover a single individual during 

 August and September, although I visited them on several occasions. 



Early in August a number of specimens were found creeping upon 

 Bryopsis plumosa at low water, south-east of Drake's Island. 



It cannot be stated of this species that it is inconspicuous when 

 creeping over the green weeds which it usually frequents ; its black 

 colour renders it at once noticeable. 



Mr. Thomas Scott ^ has recorded this species from "pools among 

 the stones left dry at low water a little east of Newhaven Pier, 

 August, 1887,^' and observes that it is not easily perceived except 

 when crawling. I have myself found it at Lytham, on the Lan- 

 cashire coast, in shallow muddy pools which receive fresh sea-water 

 only at spring tides and are dried up during neap tides. The speci- 

 mens were either creeping over the mud or over small green Oon- 

 fervae. They were buried in the mud during the dry seasons, and 

 appeared to survive them.

Six specimens were found creeping over Cladophorse in a tide-pool 

 south of the bathing pond on August 19th, 1890. None were to be 

 found a month later. This species is one of Mr. Cocks's discoveries 

 at Falmouth.
