Lagena favoso-punctata, H. B. Brady (PL LVIII. fig. 35 ; PL L1X. fig. 4 ; 
Pl. LXI. fig. 2). 
Lagena favoso-puudala, Brady, 1881, Quart. Journ., Micr. Sci., vol. xxi., N. S., p. 62. 
Test ecto- or ento-solenian, shape variable ; surface areolated or reticulated, with 
a conspicuous orifice or perforation in the middle of each area or depression. Length, 
=^th inch (0'34 mm.), or less. 
The three figures grouped under this varietal name differ a good deal in point of form, 
one being pyriform and ectosolenian, another subglobular, caudate, and entosolenian, and 
the third, oval, compressed, and wide-mouthed ; but they agree in the character of their 
surface-ornament. 
The specimens were all obtained on the shores of New Guinea, two of them from the 
north coast, 17 fathoms, the other from Torres Strait, 155 fathoms.

Lagena Icevigata, Robertson, 1883, Trans. Geol. Soc. Glasgow, vol. vii. p. 24. 
Of the bilaterally compressed varieties of the genus, Lagena Icevigata is the simplest. 
The general outline of the test is pyriform ; the apertural end slightly drawn out, the two 
faces convex, and the peripheral edge subangular. The aperture is entosolenian, and the 
external orifice generally, though not always, a long slit on the median line at the 
narrower extremity of the shell. 
Lagena Icevigata is found in every part of the world. The Challenger collections 
have yielded specimens from depths ranging from 2 fathoms to 3125 fathoms. 
It has been observed in the Chalk of Riigen (Marsson), in the Eocene deposits of 
Paris (Terquem), in the Septaria-clays of Germany and in the Salzthon of Wieliezka 
(Reuss), in the Miocene of Vienna (Czjzek), and of Lower Bavaria (Egger) ; in the Miocene 
and Pliocene of Southern Italy (Seguenza), and in the Post-tertiary clays of the west of 
Scotland (Robertson).
