from Puffin Id., shows that the teeth on the lower anterior 

 margin of the cephalothorax differ from both species, so 

 that this may be a vaiiable character. If so, E. nana can 

 hardly be separated from E. truncatida, Bate. 



*Nannon2jx spinimanus, 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; maxil- 

 lipedes also diff'erent. 



*Socarnes erythrophthalmus, Eobertson ; Port Erin 

 15 to 20 fathoms, March 24th, 1894 ; Menai Straits. 



Urothoe hrevicornis, Bate ; off Kitterland, 20 fms., male. 



Phoxocephalus fultoni, Scott ; Port Erin, 15 to 20 

 fathoms ; Menai Straits. 



*Harpinia Icevis, Sars, two specimens in mud, from 45 

 fathoms ; 7^- miles west of Niarbyl, on July 8th (new to 

 Britain). 



*Gammaropsis (? n. sp.), in sandy mud, from 30 

 fathoms, W. of Dalby, on July 8th. This is probably a 

 new species near G. melanops (Sars), but differing in the 

 form of the propodos of the first gnathopods and in the 

 secondary appendage of the upper antennae, which is 

 three jointed, the last joint being minute.
