Dominican Sections — Maury 



also living on the neighboring Jamaican coast. Dr. Dall in 1903* 

 noted that nearly 20 per cent of the Bow den species were common 

 to the Santo Domingo fauna. Our collections show that of Dall's 

 definitely identified species at Bowden 40 per cent are common to 

 the fauna of Santo Domingo. The reciprocal percentage is 9. 

 Further study will doubtless add a still greater proportion in 

 common, for the faunas were very closely allied.

 mingensis shows a bond between the Caroni Series and our Bluff 

 1 and Zone B faunas, Corbula vieta allies the Manzanilla beds 

 with our Bluff 2 and Zone I.
