An exceedingly rare bird everywhere, except at Dibulla, where it 

 was nearly as common as Nyctidromus albicollis gilvus. Six speci- 

 mens were taken here, nearly all around the cattle corrals, to which 

 they were doubtless attracted by the insects about the animals. Prob- 

 ably it is present at Rio Hacha also, but it was not possible to hunt 

 there at night.

Of this species Sclater writes as follows : " This fine, large Motmot I first 

 saw in 1853 in the hands of MM. Verreaux, who had then lately received two 

 specimens of it from their collector at S. Martha. ... I at that time considered 

 the bird as without doubt unnamed, and described it accordingly in Guerin's 

 ' Revue et Magazin de Zoologie.' " It is now recognized as a northern race of 

 Urospatha martii, but it is exceedingly doubtful if the type ever came from 

 Santa Marta. Not one of the collectors who have visited the region from the 

 time of Simons up to the present has detected it, and Dr. Chapman points out 

 that its known range in Colombia is restricted to the humid Tropical Zone 

 west of the Eastern Andes, and very probably the original specimens came 

 from some point in this latter section, or else, like Tanagra fulvicrissa, from 

 Panama. The present whereabouts of the type-specimen is not known to the 

 writer.
