Foraminifera, by Joseph Wright. 447 
d. RADIOLARIA. 
Oroscena Hualeyi, Haeckel (‘ Challenger’ Report on the 
Radiolaria, p. 1599, pl. xii. figs. 1, la). 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 millim. 
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 frem 8.W. Ireland with the 
type, as the ‘ Challenger’ Radiolaria have not yet been 
sent to the Natural History Museum.
