Gould’s authority. This determination seems to be, as above said, the 
sole basis for the ascribed occurrence of 0. orncitus 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 consequence of Mr. Lawrence having 
suggested the desirability of so doiug — Mr. Ober’s specimen of O. ornatus , 
collected at Saint Vincent, with the series of 0. exilis from Santa Lucia, 
and of 0. cristatus from Grenada. To my view, 0. ornatus , judging by the 
single example examined, is so exactly intermediate between exilis and 
cristatus 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 Orthorhynchus 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. 
“ ‘ Venezuela ’ ? ? ? Posterior half of crest abruptly blue. (Type of 0. 
emigrans , Lawr.) 
Grenada. Posterior half of crest abruptly blue [= cristatus, auct.]. 
Barbadoes. Posterior half of crest abruptly blue [=: cristatus , auct.]. 
Saint Vincent. Posterior third of crest changing gradually to blue = 
ornatus. 
Dominica. Tip of crest greenish-blue [= exilis, apud Lawr.]. 
Guadaloupe. Tip of crest greenish-blue [= exilis, apud Lawr.]. 
Martinique. Tip and posterior edge of crest tinged with blue [= exilis, 
apud Lawr.] 
Porto Rico. Tip and posterior edge of crest tinged with blue [— exilis, 
apud Sundv.] 
\_Santa Lucia. Tip and posterior edge of crest tinged with blue — 
exilis , apud Lawr.]. 
Antigua. Crest entirely green, more golden anteriorly [== exilis, apud 
Lawr.]. 
Saint Thomas. Crest entirely green, more golden anteriorly [= exilis 
auct.]. 
Barbuda. Crest entirely green, more golden anteriorly [= exilis , apud 
Lawr.].” 
‘•The above,” adds Mr. Ridgway, “are the localities represented by 
specimens of Orthorhynchus in the National Museum collection. You will 
observe by my remarks that there is a complete intergradation between cris- 
tatus and exilis.” 
In regard to 0. emigrans, one of the types of which Mr. Ridgway kindly 
loaned me (Nat. Mus., No. 74,009, u $ , Venezuela. From G. N. Law-
