292 Mr. Henry B. Brady on 
the five western Scottish localities contained in our Table, but 
through the remainder of the list it is pretty evenly distributed.

It may be fairly questioned whether it is worth while to 
separate Lagena Lyellit from its direct type L. sulcata. Re- 
garding it as the distomatous variety of the latter species, its 
distinctive characters are of the same value as those of L. di- 
ut two brackish-water examples have occurred in these 
examinations—one fromthe Frith of Forth (Bo'ness), the other 
from the Montrose Basin. 
Lagena levis, Montagu, sp. 
Vermiculum leve, Montagu (1803), Testacea Britannica, p. 524. 
Distribution almost exactly corresponds with that of L. sul- 
cata, but it is not quite so common. 
Lagena gracillima, Seguenza, sp. Pl. XI. figs. 6 a-c. ` 
Amphorina gracillima, Seguenza (1862), Foram. Monotal. Mioc. Messin. 
p. 51, pl. 1. fig. 35. 
Lagena gracillima has scarcely been recognized hitherto as 
a British recent species, and it is best known as a Tertiary 
.  * British Association Reports, 1866, (Transactions) p. 70.
