The “ Uebersicht ” of Dr. Butschli deals with the entire Order, Rhizopoda, first 
dividing it, as in Max Schultze’s scheme, into two Sub-orders, Amoebsea ( Nuda , 
Schultze) and Testacea. The former of these is again divided into two Families, 
Amcebcea lobosa and Amosbcea reticulosa, to one or other of which the whole of the naked 
types are assigned. The arrangement of the Testacea is as follows : — 
Butschli, 1880. 
f Sub-order I. AMCEBACA, Ehrenberg. 
RHIZOPODA, | Sub _ order IL TESTACEA, Scbultze. 
Sub-order — TESTACEA, M. Scbultze. ( Thdlamophora , E. Hertwig.) Including all testaceous Rhizopods, 
whatever the structure of the test. 
A. Tribe. — Imperforata, Carpenter.

2. Euglypliina, Butschli. 
3. Gromiina, Butschli. 
4. Amplmtomina, Butschli.
