the case, but without reaching any definite conclusion. The lata 

 Count von Berlepsch formally separated the southern form in 1888, 

 on the basis of the larger size and different coloration shown by 

 two specimens from Veragua, and the name he gave has been ac- 

 cepted in a subspecific sense by Mr. Bangs and Mr. Ridgway for 

 examples from that region. Both Mr. Ridgway and Mr. Carriker 

 remark the intermediate character of Costa Rican specimens, but 

 conclude to refer them all to cuUcivorus proper. After again going 

 over the case with considerable additional material, however, I am 

 satisfied that placing the birds from northwestern Costa Rica with 

 true culicivorus, and those of all the rest of the country with godinanl^ 

 really expresses the facts better than the other arrangement. Cer- 

 tainly, three birds from Guayabo, collected by Mr. Ridgway himself, 

 are absolutely identical with Panama specimens, and others also 

 are very close. I think it better to keep all the more greenish- 

 backed birds with godinani^ the more so as the series from north- 

 western Costa Rica, taken as a v.hole, are obviously grayer above 

 than the others. The only other alternative would be to separate the 

 Costa Rican bird under a new name, which is not advisable. The 

 larger size of godmani^ upon which von Berlepsch laid so much 

 stress, proves to be too slight to be of any diagnostic value, and the 

 color of the coronal spot also varies, although it is apparently more 

 often tinged with orange rufous than in Mexican specimens of 

 cuUcivorus.
