maxillipeds ; the whole animal is also short and robust, and 

 very different from the more elegant L. galei which is also 

 sometimes met with at the base of the claspers. 



6. Lernseopoda similis sp. nov. 

 (Plate LXI, figs. 3, 4.) 



Female. Somewhat similar in general appearance 

 to LemsBOpoda cluthae, but the head tolerably elongated ; 

 the second maxillipeds short, free except at the ex- 

 tremities, where they become united to a chitinous, 

 horn-coloured button which penetrates the tissues of 

 the host. Genital segment elongate-pyriform, widest 

 posteriorly. Abdomen nearly obsolete, furnished with 

 two tolerably long digitiform processes. Egg- strings 

 long, narrow-cylindrical; ova small, numerous. 



Mouth-appendages apparently somewhat similar to 

 those of Lernseopoda cluthde. Colour yellowish grey. 

 Length to the end of the posterior processes about 

 8 mm. 



Habitat. Parasitic on the gills of the blue or givy 

 skate (Raia batix) captured in the Firth of Clyde at 

 Stations I and II in December 1899. 



This species may be distinguished from L. clutlix-, which 

 1 it somewhat resembles, by the short second maxillipeds, 

 and by the form of the head.

" A few male specimens of what appears to be a 

 species of Lernseopoda were obtained on the gills of an 

 opah or king-fish, Lampris pelayicus (Q\nm.) = Lampris 

 luna, Grmel.), forwarded from Shetland to the Fishery 

 Board's Laboratory at Bay of Nigg, 10th October 

 1900 ; no females were observed. . . . The body 

 of this parasite of the king-fish is comparatively 

 slender; it tapers more or less gradually towards the
