KEW SPECIES OF EDEIOPHTHALMA. 229 



Upper autennse. — The first joint more than twice as long as tlie 

 two next, finely granulated on the inner side of the proximal half ; 

 flagellum rather longer than the peduncle, 15-jointed ; accessory- 

 appendage 11-jointed. 



Lower antennae. — Pirst joint more than half ag long as the 

 second, 3rd very small, 4th and 5th equal, three times as long as 

 the 3rd ; flagellum 11-jointed ; anteanal scale with 14 setse. 



First legs (chelipedes) as in A. spinosus (M. Sars), except 

 that the tooth on the lower margin of the 1st joint is much 

 smaller. 



The remaining legs closely resemble those of A. talpa (Mont.) 

 and A. spinosus, as figured by G. 0. Sars respectively in " Mid- 

 delhavets Saxisopoder " (Archiv for Mathematik og Naturv., 

 B. xi. 1886, p. 263, pi. 2), and ' Crustacea of Norway,' vol. ii. 

 Isopoda, p. 7, pis. i. & ii. The number of spines on the fossorial 

 legs is apt to vary — in the specimen described they difiered on 

 each leg. 



TJropoda much as in A. spinosus ; the first three joints of the 

 appendages are much longer than the succeeding ones. 



Length 10 mm. 



This species is nearest A. talpa (Mont.), from which it differs 

 in the form of the rostrum (which wants the spiniform tip figured 

 by Gr. O. Sars, I. c), in the absence of ventral spines, by the 

 comparative shortness and width of the pleou and telson, and in 

 the form of the latter, which is wider in froat than behind, while 

 in A. talpa and A. spinosus it is the reverse. 



A single female was taken by Mr. F. W. Gramble between 

 tide-marks on Church Island, Valentia Harbour, in August 1896. 

 There are also two specimens in the Dublin Museum of Science 

 and Art from the "West Coast of Ireland, the exact locality of 

 capture not being known.
