examination this wing was measured without noticing the slight 

 break indicated. 



Following are measurements from the Hispaniolan series; 10 

 males, wing 169.4-178.5 (171.6), tail 129.0-155.6 (147.7), culmen 

 from cere 22.8-28.3 (25.7), tarsus 15.2-18.3 (16.9) mm. 



Eleven females, wing 162.5-170.0 (166.8), tail 131.5-156.5 (147.1), 

 culmen from cere 23.3-25.9 (24.5), tarsus 15.3-18.7 (16.9) mm. 



The paroquet is entirely green except for more or less mixture of 

 red on the under wing coverts that some times shows on the edge 

 of the wing. The long, graduated, pointed tail serves to distinguish 

 it readily from the square tailed parrot.

Brisson describes and figures the yellow-billed cuckoo from a 

 specimen sent by Chervain to de Reaumur. Cherrie relates that at 

 the beginning of May, 1895, at Santo Domingo City this species 

 suddenly appeared in numbers so that on May 2, 3, and 4 he collected 

 five pairs. One female secured held an egg in the oviduct that 

 would have been deposited within two days. Beck collected one at 

 Sanchez November 22, 1916, and one at Santo Domingo City May 

 28, 1917. Hartert informs us that four specimens in the Tring 

 Museum collected by Kaempfer were secured near Tubano, in the 

 Province of Azua, from August 9 to 19, 1923. They were found
