 p. 458-459, pi. 2, figs. 13a, b, 14a, b, 15a, b, 1952. 



A few living representatives of this species were found at stations 

 48, 62, and 71. One dead specimen was found at station 51. The 

 specimens were most fragile and when dried became distorted.

This species is somewhat variable in form. The test is often fragile, 

 and some specimens have very indistinct morphological features. 

 Most individuals are concavo-convex, the dorsal side being convex. 

 The umbilicus is usually deep, and the sutures on the ventral side be- 

 come curved as they approach the periphery. The final chamber on 

 the ventral side is often inflated. 



Living and dead individuals of T. squamata are widely distributed in
