 "The nautiloid aspect of the test is perhaps a more constant 

 and more noticeable feature of Anomalina ammonoides than of 

 any other member of the group. The shell is generally much 

 compressed, and nearly equally convex on the two sides ; the 

 peripheral edge is round, and the aperture is placed almost sym- 

 metrically in the median line. In certain characters, however, 

 the species betrays a tendency to variation. Some specimens are 

 depressed at both umbilici (fig. 3), others are umbonate at one or 

 both (fig. 2); sometimes the earlier convolutions are visible to a 

 nearly equal extent on both faces; sometimes, on the other hand, 

 they are nearly involute on the inferior side, though the shell 

 retains its bilateral symmetry, as in Reuss's figure. The coarse 

 perforation of the shell-wall is usually more conspicuous on the 

 inferior than on the superior face." — Brady, loc. cit.
