An oblong, not very thick shell, only slightly higher behind than in 
front, the basal margin straightened, the beaks at or near the anterior 
third of the length. The most perfectly preserved shells show a fine,

beautifully regular corrugation, broadly V-shaped at the beaks, the 
anterior members short, the posterior extending some distance, some- 
times as much as 15 mm. along the posterior ridge (Fig. 91, a young 
shell 31 mm. long). The young shells are therefore very similar to A. 
divaricata (v. Martens), based upon a young specimen. In many 
examples little or nothing of this corrugation can be seen. On the median
