W. B. Carpenter and A. M. Norman have reported (P. R. Soc. xxv. 
pp. 202-215 and 223-227) upon the Foraminifera dredged in the expedi-

penter, a peculiar series (the third with the perforata and imperforata^ 
Lituolai^ Khahdammina)^ especially characteristic of the great depths. 
A remarkable sand-incorporating Nodosaria from Davis Straits (1350 
fathoms) may be noticed ; Astrorrhiza catenata, sp. n., L c. p. 213. A new 
pelagic generic type, Hastigerina. murrayi, Wyv. Th., is figured, P. R. 
Soc., xxiv. pis. xxii. & xxiii., accompanying Murray’s report on the work 
done on board tho “ Challenger.” Also (pi. xxiv.), some new deep-sea 
Radiolaria, provisionally designated as “ Challengeridce'^ * According to 
Wallich (19), “ the spined Glohigerinmtoxmdi abundantly at the surface 
of tropical seas have nothing to do with those that form the deposits at 
the bottom.”
