also at Bagaces, Miravalles, and Barranca, but is rare at all localities 

 except the first mentioned. The Costa Rican range of this bird is 

 probably the lower parts of the region from near the head of the 

 Gulf of Nicoya to Nicaragua. It is not found on the eastern slope, 

 this race being confined entirely to the Pacific. True superciliaris 

 occurs farther north, on the eastern side.

 A series of skins from Costa Rica agrees very closely with another 

 series from British Honduras, both exhibiting about an equal amount 

 of variation in the lack or intensity of the cinnamomeous wash on 

 the chest and abdomen, lighter or darker shade of green on the back, 

 and amount of purple mixed with the blue of the nuchal band. This 

 is a very common bird throughout the whole of the plateau region and 

 the Pacific slope, from Chiriqui to Nicaragua. Like the other mot- 

 mots, it lives in the forest, although it frequents the open woodland 

 more than any of the other species. Mr. Cherrie gives an excellent 

 description of the habits of the bird and its nest (Auk, IX, 1892, 322).
