' AMPIIIPODA. 



' Lysiannx longicorniti, Lucas ; Menai Straits. 



' Nannonyx spinhnanvs, n. sp., Menai Straits, differs from the only 

 other known species in the following points : Anterior coxal plates about 

 the same depth as the body ; eyes very large, dark brown ; propodos of 

 first gnathopod with five or six strong denticles on the hind margin ; third 

 joint of last pereiopods but little expanded behind ; maxillipedes also 

 different. 



' Tryphosa nana, Kr. ; Menai Straits. 



' Socarnfis erythrophthalnntg, Robertson ; Port Erin, 15 to 20 fathoms, 

 March 24, 1894 ; Menai Straits. 



' Urothoe brevicornis, Bate ; off Kitterland, 20 fathoms, one male. 



^ riioxocephahis Fulioni, Scott; Port Erin, 1.5 to 20 fathoms ; Menai 

 Straits. 



' AmpeUsca macrocephala, Lilljcborg ; Port Erin. 



^ Mctopa Alderi, Bate ; Menai Straits, large specimens, male and female, 

 6 mm. This species has not been met with in the L.M.B.C. district, 

 except at Puffin Island. 



' Metopa rubrovitfala, Sars ; Menai Straits, Little Orme. 



' Leucothoi'' LiUjeboryii, Boeck ; Port Erin, 15 to 20 fathouLS. 



' Monocnhdes carinatus, Bate ; Port Erin, outside harbour. 



' Stenoj.leiistes nodifer, Sars, erroneously reported last year as S. 

 Mahngrenl, Boeck. In the specimens taken the elevated lobes on the 

 hind dorsal margin of the first two pleon segments were reduced to a mere 

 emargination of the segment. 



' La/ystius sturionin, Kriiyer, one specimen from the Liverpool 

 Fisheries Laboratory, found under the pectoral fin of a cod. 



' Iphimedia minuta, Sars ; Colwyn Bay, Port Erin. 



' Eush'us longipes, Boeck ; Port Erin. 



^ D examine thea, Boeck ; Port Erin Harbour. 



' Tritceta gibbosa, Bate = T. dolicho7iyx, Nebeski, <?. Very abundant 

 among sponges, Menai Bridge. All the specimens that had the elongated 

 flagellura and furred upper surface of the peduncle of the lower antennae 

 characteristic of the adult male had also the peculiar notched anterior 

 margin of the propodos of the first gnathopods as in T. doliclionyx, while 

 none of the females or young had it. I believe I have once seen an adult 

 male (dug out of the test of an ascidian) with the first gnathopod as in the 

 female. This may possibly be a case of dimorphism. 



' Liljeboryia pallida, Bate ; Port Erin. 



' Mcera semiserrata, Bate ; Port Erin. 



' Mcera Batei, Norman ; Port Erin. 



' Gtce7-nea coalita, Norman ; Port Erin, 15 and 20 fathoms. 



^ Leptocheiruti pectinatiis, Norman ; Port Erin, Menai Straits. 



* Aufonoe longipes, Lilljeboi'g ; Menai Bridge. 

 ' Jannssa capillata, Rathke ; Port Erin. 



* Podocerus cumbrensis, Stebbing and Robertson ; Menai Straits, Colwyn. 



* Colomastix jncsilla, Grube ; Menai Straits. 



' Corophitim crassicorne, Bruzelius ; Little Orme. 



' Corophium Bonellii, Milne Edwards ; Little Orme, Port Erin. 



' There still remains a quantity of material to be examined.'
