Mr. Ridgway separated the Yucatan bird from the South-American Ceryle superciliosa 

 under the name of C. superciliosa stictoptera, stating that the wings are spotted with 

 white, those of the southern birds being nearly or quite plain. All our specimens from 

 Central jimerica agree with this definition ; but only four out of twenty-one birds 

 from South America have unspotted wings, the other seventeen have the wings all 

 more or less spotted, and are thus not distinguishable from the northern birds. As the 

 character thus breaks down dividing these birds we are unable to discriminate more 

 than one species, to which the old name Ceryle superciliosa is applicable. There 

 appears to be no break whatever in the range of the species, as it is found, though 

 sparingly, in every river and stream of the lowlands of Tropical America. In Mexico 

 it has been found in several places in the southern portion of the State of Vera Cruz 

 and also on the Isthmus of Tehuantepec. In Guatemala we found it close to the 

 shore of the Pacific at the mouth of the Rio Samala, and also at Choctum, one of the 

 favourite hunting-resorts of the bird-collectors of Coban, in the interior of Vera Paz, 

 at an elevation of about 1200 feet above the sea. It has also been met with in all the 

 other Central-American States and in the State of Panama, both on the Line of 

 Railway as well as on the Isthmus of Darien. 



In habits this species has no peculiarities that we know of to distinguish it from the 

 other species of Ceryle inhabiting the same districts.
