1900-1.] Foraminifera in the Living Condition. 
391 
Notes on the Appearance of some Foraminifera in the 
Living Condition, from the ‘ Challenger 5 Collection. 
By Frederick Chapman, A.L.S., F.R.M.S. Communicated 
by Sir John Murray, K.C.B., F.R.S. (With Three 
Plates.) 
(Read July 15, 1901.) 
The habits and mode of existence of Foraminifera are always 
interesting subjects to students of the Protozoa, and this fact alone 
might perhaps justify the following notes, even were they not 
accompanied by the valuable drawings prepared by Mr G. West, 
from pencil sketches and microscopic slides made by Sir John 
Murray from the living Foraminifera collected during the voyage 
of H.M.S. ‘ Challenger.’ 
The writer is greatly indebted for the privilege of examining 
and describing these drawings, and a collection of mounted speci- 
mens of a like character, to Sir John Murray, K.C.B., LL.D., 
F.R.S., who generously placed them in his hands a year or two 
-ago. 
The species of Foraminifera depicted on these plates are : — 
Textularia conica , d’Orbigny. 
? Discorbina globularis (d’Orbigny).
