sutures ; tlie primordial segment relatively large and terminating in a point, the 
acuminate and pierced with a rounded orifice. 
Amongst the curved Nodosarice with straight 
sutures, it is convenient to distinguish by name the 
group of intermediate forms characterised by the 
foregoing description ; those, namely, which are sub- 
cylindrical at the commencement and subsequently 
moniliform, most of the chambers having no external 
depressions on the septal lines, a few of the later 
ones becoming inflated or subglobular. Such shells 
are as a rule few- chambered and stoutly built ; they 
are generally of nearly even width, tapering a little 
towards the initial end. 
Speaking in general terms, the distribution of 
Nodosaria pauperata, whether geographical or geolo- 
gical, corresponds with that of the closely allied 
Nodosaria far cimen and Nodosaria communis.

This is a smooth, attenuated, and generally Dentaline variety, of which the early 
segments are short, and those subsequently formed of elongate-oval contour. Reuss 
allows to Nodosaria consobrina considerable range of variation as to minor characters, and 
gives references to an instructive series of figures in von Schlicht’s memoir. The little 
two-chambered shell figured by Parker and Jones under this name (Phil. Trans., vol. civ. 
pi. xvi. fig. 3) appears to me to belong to Nodosaria calomorpha, Reuss, a very distinct 
form. 
The distribution of Nodosaria consobrina cannot be distinguished from that of the 
more slender variety, which follows next in order.
