Review of the New York Geological Reports. 



Plate 112, 





1. Trinacleus caraclaci. 2. Strophomena. 



3. Strophomena nasuta. 



The first of these fossils is found towards the upper part of the 

 Loraine shales. Dr. E. thinks it is identical with the true carao- 

 taci of the Caradoc ; it also resembles a Cincinnati species, but we 

 are not at present prepared to subscribe to the identity of either 

 of these species. 



The two Strophomena are, as far as can be determined by 

 comparing figures with fossils, the same as two species common 

 both in Ohio, Indiana, Iowa and Wisconsin.
