a recent expedition from Port Erin. Large quantities of 

 opliiuroids, chiefly OpJiiocorna nigra and Ophiotlirix 

 fragilis, were amongst the dredged material, and it is 

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

 mens of Cancerilla tuhidata, 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^. 



Pseudanthessius saiwagei, Canu. 



A few specimens were obtained by washing a number 

 of Spatangus purpureus, 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. 



Lickoinolgus (Doridicola) agilis, Leydig, was found in 

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



Family Artotrogid^. 



AcontiopJiorus eloiigatus, Scott. 



One specimen was found among the strained washings 

 of Pecten maxiimis, dredged at 15 fathoms, off Port Erin, 



Family Caligid^. 



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.
