REPORT ON THE FORAMINIFERA. 
487 
fathoms and 620 fathoms, the remaining six at depths of 2300 fathoms or more. I learn 
from my friend Mr. F. W. Millett that specimens have been found cast up on the coast 
of Galway. 
Lagena auriculata, H. B. Brady (PI. LX. figs. 29, 33). 
Lagena auriculata, Brady, 1881, Quart. Journ. Micr. Sci., vol. xxi., N. S., p. 61. 
Test pyriform compressed, ento- or ecto-solenian ; bearing oh each side, near the base, 
a loop-shaped laminar extension of the wall enclosing a portion of the lateral margin. 
Margin sometimes carinate or alate, the keel or wing dividing near the base on each side 
so as to form similar loops ; when broad, the wing is often conspicuously tubulated. 
Length, ^pth inch (0'42 mm.). 
Lagena auriculata is closely allied to the species last described, Lagena ftmbriata, 
but in the latter the entire base of the test is surrounded by a vertical wing, whilst in the 
present form two smaller areas, one at each lateral margin near the base, are so 
enclosed. 
Lagena auriculata is found in the North and South Atlantic and in the South Pacific, 
at depths ranging from 1370 to 2740 fathoms. It has been noticed in one locality, off 
Gomera, Canaries, at less depth, namely, 620 fathoms, but the specimens were small and 
poorly developed. 
Lagena auriculata, var. costcitci, H. B. Brady (PI. LX. fig. 38). 
Lagena auriculata , var. costata, Brady, 1881, Quart. Journ. Micr. Sci., vol. xxi., N. S., p. 61. 
This variety partakes of the general characters of the type, but the body of the test is 
costate, resembling Lagena sulcata, and carinate. 
It has been dredged in the Low Archipelago, 2350 fathoms, and in the deep area of 
the North Pacific, 2300 fathoms. 
Lagena alveolatci, n. sp. (PI. LX. figs. 30, 32). 
Test pyriform compressed, lateral edges obtuse or rounded ; base broad and round in 
outline, rarely mucronate ; furnished with a median and two lateral carinse, which unite 
so as to form two loops on each side of the test, usually separated by a central depression. 
Length, -g^th inch (0'5 mm.). 
This belongs to the same group of forms as Lagena auriculata, but differs from that 
species in having the spaces enclosed by the c a rinse divided by the central keel, so as to 
form four loops instead of two. 
Lagena alveolata is only found in deepwater. It occurs in the North Atlantic, 2750
