The term Polymorpliina amygdaloides is employed to distinguish the more or less 
flattened varieties of the typical Polymorpliina lactea. The degree of lateral compression 
varies with every specimen, and almost every gradational step in the series has at one 
time or other been made the basis of a fresh “ specific ” name. Thus Polymorpliina 
minuta, Roemer, is almost typical, that is to say, nearly round in transverse section ; 
Globulina guttula, Reuss, is the same thing but a little more oval in section ; Poly- 
morpliina depauperata, Reuss, is more distinctly compressed ; and Polymorpliina 
amygdaloides, Reuss, has flattened sides. Many other names have been employed either 
for intermediate forms or for specimens presenting slight irregularities of external contour, 
but they only serve to complicate an already overburdened nomenclature. 
No separate account can be given of the distribution of such forms ; wherever the 
type is found, more or less compressed or irregular modifications present themselves.
