206 HISTORY OF BRITISH CRUSTACEA. 



First pair of antennse simple, conical, very short. Two first 

 pairs of legs not prehensile. Telson lanceolate. 



Hyperia Latreillii, Milne-Edwards. (Plate XI. fig. 3.) 

 — Of a brownish colour, about eight lines long ; the lower 

 antennse as long as the upper, and of the same form ; the 

 first six or seven joints of the filament of upper and lower 

 antennse fused ; fivelast pairs of legs nearly all of the same 

 size ; terminal abdominal plate triangular, blunt at the end. 



Tound on the south coast of England, and obtained by 

 Mr. Ball in great numbers in the cavities of a Rhizostoma, 

 at Youghal. To this genus also belongs the C. Gam mar us 

 Galba of Montagu, found on the south coast of Devon, and 

 met with by Mr. Hyndman, on the Dublin coast, in the 

 pouches of Rhizostoma Cuvieri. Mr. Spence Bate regards 

 this as synonymous with Montagu's species. 



Hyperia oblivia, M. Edwards. — Lower antenna longer 

 than the upper, and the segment of the filament of the 

 upper antenna only fused ; the legs long. 



Moray Firth, Rev. Mr. Gordon, who sent it to Mr. Spence 

 Bate.
