168 Allen on Birds of Santa Lucia. 



Gould's authority. This determination seems to be, as above said, the 

 sole basis for the ascribed occurrence of 0. ornatus in either Martinique or 

 Santa Lucia. 



Since the above was put in type I have been able, through the kindness 

 of Mr. Ridgway, to compare — in consetjuence of Mr. Lawrence having 

 suggested the desirability of so doiag — Mr. Ober's specimen of 0. ornatux, 

 collected at Saint Vincent, with the series of 0. exilis from Santa Lucia, 

 and of 0. cristaluA from Grenada. To my view, 0. ornatus, judging by the 

 single example examined, is so exactly intermediate between exilis and 

 crislatus that it is impossible to refer it to the one rather than to the other, 

 and it therefore seems necessary to adopt respecting it one or the other of 

 two alternatives, — either to consider all these forms as geographical races 

 of one species, or allow to each specific rank. 



Correspondence with Mr. Ridgway respecting these forms has led to his 

 kindly preparing for me the subjoined list of localities represented by 

 specimens of Orthorhi/nchus in the National Museum, with remarks respect- 

 ing the color of the crest at the several localities named. The words in 

 brackets are added by me.

'•The above," adds Mr. Ridgway, "are the localities represented by 

 specimens of Orthorhynchus in the National Museum collection. You will 

 observe by ray remarks that there is a complete intergradation between cris- 

 tatus and exilis."
