by the more irregular warts, and from the latter by the larger 

 size and in the more developed digital disks. It may turn out 

 not to be distinct. 



From the Isle of Pines I have seen cuneatus and pinarensis. 



The species found in the neighborhood of the Harvard Biologi- 

 cal Station at Soledad are varians, sonans, varleyi, cuneatus, 

 ricordii, greyi, and atkinsi. Of these, cuneatus and ricordii are 

 common and often met with; atkinsi is common in the dry woods 

 at Guabairo but rare elsewhere ; greyi is quite common ; varleyi is 

 common but small and seldom seen; sonans is common in bushes; 

 and varians is uncommon and only in tall trees. 



At Mina Carlota in the Trinidad Mountains, atkinsi and 

 ricordii reached the mine itself at 1200 feet altitude, but did not 

 extend farther into the mountains, being there replaced by 

 emiliae and dimidiatus, and by casparii, respectively. Varians 

 and varleyi did not seem to occur. Eileenae, the ''Kolin" (not 

 dimidiatus, as I erroneously suggested in 1925), was found at the 

 mine and higher up, while greyi, cuneatus, and sonans were at all 

 altitudes. 



At Hoyo Colorado, in the San Bias division of the Trinidad 

 Mountains, atkinsi was found in company with dimidiatus and 

 casparii.
