the chief interest centres round the variety, fig. 2, in which, in 

 some cases, the chambers on the inferior surface assume the form 

 of erect cones, the sutures being very deep ; in fact, the last two 

 ■chambers in some of the specimens are almost independent of each 

 other. The keel is well developed. Two of the tests show colour, 

 one being of a light brown tint and the other much darker, 

 especially in the earlier chambers. 



Four occur similar to the " Challenger " fig. 3, and fourteen 

 of the variety specially mentioned. These latter vary in size.

This rough and spinous Anomalina is represented by two 

 excellent specimens. 



Anomalina simiosa, sp. n. (PI. VI, figs. 22-25.) 



Test compressed. Superior surface flat or slightly concave. 

 Inferior surface slightly convex, with sloping sides and generally 

 a little hollowed in the region of the earlier chambers. Peripheral 

 edge acute. The cham])ers, of which there are five or six in the 

 outermost whorl, are irregular in shape, .sinuous and difficult to 

 distinguish (except when the test is mounted in Canada balsam 

 and viewed as a transparency), owing to the excessive limbation, 

 which is often broader in parts than the adjacent portion of the 

 chamber. The limbation along the septal lines is raised and 

 rounded, varies in width and is extraordinarily sinuous. The 

 test is semi-transparent, a little roughened on the inferior face. 

 The aperture is difficult to distinguish, but appears to be situated 

 near the inner edge of the very narrow septal face of the final 

 chamber. The end of the final chamber does not always project
