d. Radiolaeia. 



Oroscena lluxleyi^ Haeckel (' Challenger ' Report on the 

 Radiolaria, p. 1599, pi. xii. figs. 1, 1«). Found in 

 ooze, dredged in 1000 fath., S.W. Ireland. 



Two complete spheres and a fragment of this form 

 were sent; but none of the long branched spines, which 

 radiate from the surface of the sphere, had been pre- 

 served. The diameter of the shells is from 1"75 to 

 2 millira. 



The type specimen, which is in the ' Challenger ' 

 collection, was obtained from a depth of 2740 fath., west 

 of the Canary Islands ; but there has been no opportunity 

 of comparing the specimens from S.W. Ireland with the 

 type, as the ' Challenger ' Radiolaria have not yet been 

 sent to the Natural History Museum.
