REVISION OF L.M.B.C. AMPHIPODA. 439 



pectinatus (Norman) wliich I consider identical with L. 

 pilosus (Zadd.) this appendage is two-jointed and very 

 small and the minute second joint might easily be over- 

 looked by Muller, as indeed might the whole appendage 

 by Zaddach. Again, the form of the propodos of the first 

 gnathopods, described by Zaddach as somewhat swollen 

 and broader towards the extremity, does not agree with 

 Sars' figm^e ; and the dactylus of the second gnathopods 

 which is described by Zaddach as straight and feeble 

 (''... migue recto debilique terminatm' ") and which in 

 L. pectinatus is a very characteristic thin narrow lamina 

 terminated by a small tuft of setae, is quite normal in L. 

 hirsutimanus. Finally, Zaddach could hardly have failed 

 to call attention to the powerful second uropods described 

 by Norman (Shetland Dredging Eep.) under P. hirsiUi- 

 mana had they existed in his species. 



Gammaropsis erythrophthalma (Lillje.). 



Turbot Hole, Puffin Island, 15 f. ; Angiesea coast, 20 f., 

 8/6/89; 16 m. of N. of Holyhead, 45 to 50 f. ; between 

 Mersey Bar and Isle of Man, 20 to 30 f., 28/8/86 ; 8 m. W. 

 of Fleshwick Bay, 30 to 33 f . [off Blackcombe ; Lambay 

 Isle] . Length 7^ mm. 



Gammaropsis nana, Sars. 



My specimen differs sHghtly from Sars' description, the 

 secondary app. of upper ant. being three-jointed (the last 

 very small) and the dactylus of first gnathopods finely 

 serrate on the proximal half. The eyes are oval — not 

 round. Otherwise they agree. 5 miles W. of Dalby, 

 Isle of Man, 30 f., sandy mud, 8/7/94; 8 miles off Flesh- 

 wick Bay, 30 to 33 f., 5/6/92. Length of female with 

 ova 25- mm. 



MegampJiopus cornutus, Norman. 



Podoceropsis inter media, Stebbing. 

 Protomedeia longimana, Boeck.
