The test of Lagena striatopunctata is oval, pyriform, or flask-shaped, and either ecto- 
or ento-solenian. It is decorated externally with tolerably stout longitudinal costae, from 
six to twenty in number, bearing conspicuous pseudopodial foramina. The perforations 
are placed either in single rows down the middle of the costae, or in double lines, one on 
each side in their thickened bases. 
The species is by no means common, but occasional specimens are met with in areas 
very far apart. The distribution-list embraces localities in the Arctic Seas, the North and 
South Atlantic, and the North and South Pacific, the depths ranging from 55 to 2750 
fathoms. It occurs sparingly in comparatively shallow water on our own shores. 
Lagena striatopunctata is one of the fossil Foraminifera found by von Schlicht in the 
Septaria-clay of Pietzpuhl, in North Germany. It occurs in the Post-tertiary deposits of 
the west of Scotland (Robertson), and in those of the north-east of Ireland (Wright). 
Lagena spiralis , n. sp. (PL CXIV. fig. 9). 
Test pyriform, ectosolenian ; surface decorated with a small number of longitudinal 
costae, arranged spirally, and having a row of conspicuous perforations along the centre of 
each. Length, p^-th inch (0T7 mm.). 
This is a variety of Lagena striatopunctata with a test of minute size, adorned with 
spirally twisted instead of straight ribs. 
The figured specimen was found by Mr. Joseph Wright in the rich coral-sand from 
Raine Island, Torres Strait, 155 fathoms.
