ance of the shell is that of Sagrina rather than of Nodosaria ; and in both the localities 
named the former genus abounds. For these reasons, rather than upon any direct or 
positive evidence, the species has been placed temporarily in its present position. 
Sagrina (?) annulata, n. sp. (PI. LXXVI. figs. 20, 21). 
Test subcylindrical ; oral end rounded, aboral extremity obtusely angular or rounded ; 
composed of few (two to four), elongate, somewhat inflated segments, united end to end. 
Surface marked by closely set, slightly depressed, transverse lines. Aperture a simple 
terminal rounded orifice. Length, gLth inch (075 mm.). 
Pending the discovery of further specimens, the above characters may serve to 
distinguish an obscure species, of which only two or three individuals have been met 
with during the examination of the Challenger material. It is quite possible that the 
organism may not belong to the genus Sagrina. 
The specimens referred to were found amongst coral debris from the Honolulu Reefs, 
40 fathoms, and in sand dredged off the Azores, 450 fathoms. 
Sagrina limbata, n. sp. (PL CXIII. fig. 14). 
Test elongate, subcylindrical, compressed, tapering, somewhat twisted or otherwise 
irregular. Uvigerine portion relatively very small ; oral end rounded, aboral extremity 
angular or pointed ; segments numerous. Surface marked by a number of raised 
transverse bands of shell-substance (concealing the sutures) connected by a similar band 
on the median line on either side of the test. Aperture terminal, consisting of a large 
oval orifice with raised border. Length, -g^th inch (0'42 mm.). 
This is a minute species, the precise structure of which has not as yet been satis- 
factorily determined ; and, as a comparatively small number of specimens only have been 
found, the foregoing characters are provisional and incomplete. As a general rule the 
limbation of a foraminiferal shell follows the course of the sutural lines, but in the 
present instance it appears as though the central band was deposited in a hollow on 
either face of the test, like that which is seen in some specimens of Sagrina bifrons, and 
that it assumes to' a certain extent the character of mere exogenous ornament. This 
variety is apparently closely related to Sagrina annulata. 
Sagrina limbata has only been encountered at a single locality, — off Raine Island, 
Torres Strait, depth 155 fathoms.
