* It seems to me that this species is the Caribbee Merlin of Latham, in which 

 case it would stand as Cerchneis carrihhaarian, with the following synonymy :— 



L'Emerillon des Antilles, Briss. Orn. i. p. 385 (1760). 

 Caribbee Merlin, Lath. Gen. Syn. i. pt. 1, p. 108 (1781). 

 Falco carribbicarum, Gm. Syst. Nat. i. p. 284 (1788, ex Lath.). 

 Falco SEsalon, var. /3, Lath. Ind. Orn. i. p. 49 (1790). 

 At preseiit, however, I have not a sufficient series to determine the question.
