Characters: Shell oval, ultimate chamber projecting beyond the penultimate 
all round with peripheral edge rounded. Aperture much narrower than in B. ringens 
central »tongue» or »tooth» narrower but relatively more pronounced. 
Biloculina elongata is but an extreme form of B. rinstens and even in the 
o O 
small collection of Biloculinæ from the Pecten-conglonierate there are specimens 
which illustrate the passage from one form to the other. 
Biloculina elongata is very widely distributed in recent seas and in the fossil 
condition is common in tertiary deposits. 
Genus Miliolina, Williamson (1858). 
Shell free; convoluted, inequilateral, usually oblong, consisting of numerous seg- 
ments each of which in turn extends over the entire length of the shell. Convolutions 
not disposed in one plane, but constantly changing their direction, so that parts of 
three or more visible segments contribute in various proportions to form the external 
surface of the shell. Septal orifice generally large, alternately occupying opposite 
extremities of the shell and almost invariably furnished with an appendicular tooth. 
Miliolina grata, (Terquem).

I have been loth to describe the single specimen of the genus Miliolina obtained 
from the Pecten-conglotnerate as a new species and refer it, though somewhat doubt- 
fully, to the form designated as above by Terquem. 
The »characters» of the species as defined by Terquem are as iollows: — 
»Quinqueloculina subrotundata, plus minusve regular!, compressa, concentrice 
tenuis ornata costulis, antice et postice obtusa, circiter rotunda, loculis arcuatis, plus 
minusve regularibus, apertura arcuata, dente lato, simplici, instructa.»
