figured. Some of the specimens have the lip of the neck everted, 
similar to those found in the Red Chalk. This species is one of the 
oldest fossil forms of Lagena , occurring in strata from the Silurian* 
and upwards. It is found in zone iv., very rare ; zone v., very rare ; 
zone xi., 35 ft. from the top, very rare ; 30 ft. rare.

Hitherto this species has not been found in beds older than the 
Miocene. The specimens found in the Gault are very small and were 
obtained by very careful examination of the finest washings. It 
occurs in the Grault in zone xi., 50 ft. from the top, very rare.

This species is rather uncommon in the Gault. It does not vary 
greatly in contour from the specimen figured, but the apiculate portion 
is usually absent. Lagena aspera , though new to the Gault, is 
known as a fossil from Middle-Liassic beds, the Oolite, Upper Chalk, 
Tertiary beds, and also from recent deposits. In the Gault it occurs 
in zone iii., very rare; zone xi., 45 ft. from the top, frequent; 12 
ft., rare.

A well distributed and tolerably common form in the Gault, 
though here recorded for the first time. It has also been found in 
the Middle Lias of France and in most Tertiary deposits. In recent 
soundings it occurs in shallow water and at depths varying from 129- 
1900 fathoms. The Gault specimens vary somewhat in shape, and 
are represented on the accompanying plate by drawings from the two 
principal types, viz. the elongated or flask-shaped form, and the 
globose form. This species is found in the Gault in zone ii., specimen 
a, very rare ; zone iii., common ; zone iv., very common ; zone v., 
From the Woolhope Beds (Brady).
