178 LIVERPOOL BIOLOGICAL SOCIETY. 
Cerapus abditus, Templeton. Black Point, Anglesey, 
low water. One female. 
ISOPODA. 
*Jera Nordmanni, Rothke. Under stones, Penmaenrhos, 
27th June, 1887. Very variable in colour. 
CUMACEA. 
*Diastylis Bradyit, Norman (Ann. and Mag. Nat. Hist., 
5th series, vol. i1.). One specimen (a female), in 3 fathoms, 
Colwyn Bay, 24th May, 1887, in the ‘“‘muzzled”’ dredge. 
In my specimen the sides, as well as the ventral surface, 
of the fourth, fifth and sixth segments are spinous, and the 
postero-lateral margin of the fifth is produced backwards 
about half way between the ventral and dorsal suface 
(i.e. on the side), and terminates in a strong spine with a 
smaller spine close below it (Pl. XIILI., figs. 10 and 11). 
The only previously recorded locality for this species is 
Lough Swilly, Co. Donegal, where it was dredged in 
15 fathoms, during the ‘‘Porcupine”’ expedition in 1869. 
Mr. Norman informs me that it has been also taken on the 
Northumberland and Durham coasts. 
PODOPHTHALMATA. 
SCHIZOPODA. 
*Mysis vulgaris, Thompson. Taken in considerable 
numbers by Mr. F. Archer, at the mouth of the river Alt, 
in brackish water. A large proportion of the specimens 
had the telson deformed, as described in a previous number 
of the Liverpool Biological Society’s Proceedings. 
*Mysis Lamorne, Couch. One specimen, in 3 fathoms, 
Colwyn Bay, 24th May, 1887, in the “‘muzzled”’ dredge. 
A pretty species, with bright red thorax, maxille and 
maxillipedes, and a red spot on the last abdominal segment 
before the telson.
