EEVISION OF L.M.B.C. AMPHIPODA. 309 



17/9/94; off Port Erin, 15 to 20 f., 24/3/94; 10 to 17 m. 

 N.W. of Mersey Bar. Length 6 mm. 



I have examined the specimen marked Gammarus 

 tenuimanus, in the Sp. Bate Collection at the British 

 Museum, and am satisfied it is this species. The des- 

 cription and drawing of the second gnathopod in the Brit. 

 Sess. Eyed Crust, are very faulty ; the description in the 

 catalogue is much more accurate. 



Megaluropus agilis, Norman (Ann. and Mag. N. H., 

 Ser. 6 (1889), Vol. III., p. 446, PI. XVIII.). 



Common on the N. coast of Wales and the Isle of Man, 

 2 to 10 fath. Colouring when alive very beautiful. It 

 has a bright crimson blotch on the head above the eye ; 

 telson and base of third uropods yellow — the latter with 

 three or four opaque white spots on the outer edge of the 

 outer ramus. Length 4 mm. 



Gheirocratus sundevalli (Eathke).

 of Man, from 2 to 30 fath. Margins of the first joint of 

 all the legs and both ant. scarlet ; segments and epimeres 

 spotted with the same colour. Length 8 mm. 



Gheirocratus assimilis (Lilljeborg). 



Port Erin harbour, 28/1/93 ; 7 m. W. of Bradda Head, 

 31 f., 25/4/95. Colourless, by which, when fresh, the 

 female may most readily be distinguished from the pre- 

 ceding species. See also Norman in Ann. and Mag. 

 N. H., Ser. 6 (1889) Vol. IV., p. 131, PI. XI. and XII. 

 Length 7 mm.
