and females seem equally plentiful. The fifth feet (h, c, d) 

 readily distinguish it. 



Lahidocera acutitm, Dana. (PL XYI, fig. 6.) 

 Length 2.50 mm. One specimen, a male, of this rare 

 exotic species was found in dredged material taken off 

 Puffin Island in 10 fathoms when in company with Dr. 

 Brady. 



Anomalocera pater soni, Templeton. (PI. XVI, fig. 7.) 

 Length 3.75 mm. This large striking Copepod has 

 been frequently taken in the district, but generally when 

 it has occurred, as on two dredging expeditions round 

 about the Isle of Man, it has been in such profusion for a 

 few days as to almost fill the townets and to be clearly 

 visible on the surface from the steamer's deck. When 

 living it is of a deep green colour interspersed with 

 blue and red but so far I have been unsuccessful in pre- 

 serving its natural colour. What becomes of these 

 tremendous shoals at other times remains a mystery. 

 Dr. J. Murray considers it unlikely that an animal so col- 

 oured could be a deep water species, and we have never 

 taken it at any great depth, nor does it appear to be of 

 wide geographical distribution. Male and females were 

 equally plentiful. 



EucJueta inarina, Prestandrea. (PI. XVI, fig. 8.) 

 Length 3.0 mm. A single specimen of this well known 

 southern species, never I believe before recorded in British 

 seas was found adherent to the branchial sac of an Ascid- 

 ian dredged by Prof. Herdman in Garwick Bay, Isle of 

 Man. The presence of this animal so essentially a free 

 swimmer, in such a situation is most unaccountable. Its 

 transversely notched rostrum with two sharp teeth readily 

 distinguishes it from any other known species.
