and females seem equally plentiful. The fifth feet (0, c, d) 
readily distinguish it. 
Labidocera acutum, Dana. (Pl. XVI, 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 paterson, Templeton. (Pl. 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. 
Hucheta marina, Prestandrea. (Pl. XVI, fig. 8.) 
Length 3.0mm. 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, 1n such a situation is most unaccountable. Its 
transversely notched rostrum with two sharp teeth readily 
distinguishes it from any other known species.
