Specimens frequent and well distributed. Tending in form 

 towards T. ungeriana rather than towards the irregular, wild- 

 growing form T. variabilis, d'Orb.

Examples are not very rare but are small and weak, show- 

 ing that the conditions under which they lived were not suitable 

 to the development of the species. Of the three localities from 

 which Brady's specimens came, two are in the West Indies, and 

 the third off Pernambuco, S. America. The depths recorded 

 are from 390 to 675 fathoms. 



(Very few of the specimens can be regarded as typical. 

 The bulk of them are much more angular in periphery and tend 

 in the direction of T . ungeriana.)

Frequent and fairly distributed, the species however be- 

 comes rare in the lower Marl beds. The examples found are 

 small but typical.
