NOTES ON RETICULARIAN RHIZOPODA, 43 
IX. GLoBicERINIDH.—A compact group of essentially 
pelagic types. With the exception of a few species, gene- 
rally of small size, all have been found living in open sea, 
at or near the surface. 
G. Test coarsely perforate,a few of the higher forms with 
double chamber-walls and interseptal canals. 
X. Roratipz#.—Embraces the Rotaline of Messrs. 
Carpenter, Parker and Jones, with the addition of the genus 
Spirillina, which may be regarded as their non-septate modi- 
fication, just as Cornuspira is a non-septate Miliola and 
Ammodiscus a non-septate Trochammina. 
H. Test very finely tubulated. All the higher types 
possessing a system of interseptal canals of greater or less 
complexity. 
XI. NumMvuLinipa.—Coextensive with the Nummulinida 
of Carpenter, Parker and Jones. I have retained Fusulina 
in the place hitherto assigned to it, on the ground of 
its symmetrical contour, but, as Dr. Carpenter has 
shown, the genus has almost as much in common with 
the Rotalide.
