by its cylindrical and rather slender abdomen. The 

 occurrence of these three species in a bay gathering is 

 interesting, as they are generally regarded as oceanic 

 forms, and probably indicates an unusual flow of Atlantic 

 water into the Irish sea prior to their appearance. 

 Corycaeus anglicus, Lubbock, recorded from Port Erin 

 Bay in November, 1898, and in May, 1899, by I. C. 

 Thompson, was also present in the bay gathering taken 

 24th December, 1910, and again on 13th February, 1912. 



" Kroyeria lineata, P. J. van Beneden. In the hollows 

 between the gills of male Galeorhinus galeus, the Tope 

 or Toper, trawled on King William Bank off the North 

 of Isle of Man, April, 1912. Males and females were 

 not uncommon on specimens of that dog-fish landed at 

 Piel by Captain Wignall of the Fisheries steamer 

 "James Fletcher." This parasite is apparently con- 

 fined to male fish — at any rate we have never come across 

 it when examining females. It has hitherto only been 

 recorded from the coast of Belgium (van Beneden) and 

 the coast of Italy (A. Brian). No doubt the habitat of 

 the parasite has something to do with the paucity of 

 records. One requires to fold back the gill-rays one after 

 another to find it. 



" Eudactylina insolens, T. and A. Scott. Four speci- 

 mens of this abnormal member of the genus were found 

 on the gills of the Topers along with the Kroyeria. It 

 resembles Eudactylina acantliii in some respects, but can 

 be recognised by the incomplete segmentation of the 

 thorax and the uncinate second pair of feet." 



Mr. Scott also draws my attention to the absence of 

 any record of the crab Gonoplax; rhomboides ( = angulata) 

 in the Revised List of species recorded from the Liverpool 

 Bay Area (Brit. Assoc. Meeting, Liverpool, 1896, and in 

 Report V, Fauna of Liverpool Bay). He says: — "Its
