According to Brady, Cyclammina (Fig. 498) represents in our seas the highest type of arenaceous foraminifers. The genus is characterized by the labyrinthian structure of the test (Fig. 499), and is abundant in depths below 100 fathoms in the West Indian region. Fig'. 497- — Ammodiscus tennis. Y- (Brady.).
