SCHIZOPODA AND ISOPODA FROM THE BAY OF BISCAY. 195 



aware that lanira maculosa, Munna Boecki, and Astacilla longicornis 



have up till now been recorded from greater depths than 400 fathoms, 



so that the vertical distribution of all three has been extended as a 



result of the present material. lanira maculosa was only found at 



Stations VIII and XIII, and from Professor Hickson's report on 



the Alcyonaria of the Hurley's cruise it was at both these stations 



that the majority of the Alyconaria were taken. In shallow water 



lanira maculosa is very frequently found in considerable numbers 



crawling over colonies of Alcyonium digitatum, and in all probability 



the specimens in the present collection were clinging to the 



Alcyonarians found on the same grounds. Eurycope longipes is a 



species only recently described from specimens found off the west 



coast of Ireland on the edge of the Atlantic slope. Its occurrence 



further south on the same slope, while interesting, is only naturally 



to be expected. 



Family MGilDM. 



Mg&. Stromii, Lutken. 



Station XII. Three specimens. 



Rocinela damnoniensis, Leach. 

 Station IX. One specimen. 

 Station XII. Four specimens. 



Family CIROLANID^. 

 Cirolana borealis, Lilljeborg. 

 Station II. One specimen. 

 Station V. One specimen. 

 Station IX. Four specimens. 

 Station XII. Twelve specimens. 



Cirolana Hanseni, Bonnier. 



Station XIII. One specimen. 



Stebbing, in his report on Professor Herdman's Ceylon Isopoda, 

 suggests that this species should be referred to his genus Hansenolana, 

 while Hansen, in his recent revision of the European members of the 

 genus, still retains in it the genus Cirolana. The present specimen 

 measures only 3 mm., and is therefore smaller than Hansen's largest 

 specimens, which was 4*2 mm., and which Hansen thought to be still 

 immature. As it is obvious that adult specimens are necessary before 

 the correct genus for the species can be determined, I follow Hansen 

 in retaining it in its original genus, Cirolana, for the present. 



Eurydice truncata (Norman), 

 Station X. Fifty-three specimens.
