a recent expedition from Port Erin. Large quantities of 

 ophiuroids, chiefly Ophiocoma nigra and Ophiothrix 

 fragilis, were amongst the dredged material, and it is 

 probably from one or other of these that the two speci- 

 mens of Cancerilla tubulata, Dalyell, male and female, 

 were taken, as the species is parasitic on ophiuroids. It 

 has recently been fully described and figured in " Les 

 Copepodes du Boulonnais," by Dr. Eugene Canu. 



Family Sapphirinid^e. 



Pseudanthessius sauvagei, Canu. 



A few specimens were obtained by washing a number 

 of Spatangus purpureas, which were trawled in the 

 central area, 21 miles W.N.W. from Morecambe Bay 

 Lightship, on April 3rd. This rare species was only 

 added to the British fauna last year, when it was found 

 in the Firth of Forth, and the present is the second time 

 it has been observed in the British area. 



Lichomolgus (Doridicola) agilis, Leydig, was found in 

 the bottom tow-net, Morecambe Bay, May. 1894. 



Family Artotrogid^;. 



Acontiophorus elongatus, Scott. 



One specimen was found among the strained washings 

 of Pecten maximus, dredged at 15 fathoms, off Port Erin. 



Family Caligim:. 



Lepeoptheirus pectoralis. 



Several specimens, male and female, were found on the 

 flounder, taken off Morecambe, and also from Arnoglossus 

 megastoma, at Professor Herdman's Fisheries Laboratory.
