EEVISION OF L.M.B.C. AMPHIPODA. 437 



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 Gaminarus 

 tenuimanus, in the Sp. Bate Collection at the British 

 Musemn, 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, PL XVIII.).

Cheirocratus assmiilis (Lilljeborg). 



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

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