The Caura River specimens belong to the smaller form. The larger one, which 

 mnst be considered typical cliinopectus, dift'ers in generally slightly larger dimen- 

 sions, the bill being perceptibly longer and slightly more cnrvcd. There is also 

 more often a deep coppery gloss on tail and rump in the Trinidad birds, while those 

 from Gniana are more greenish, bnt some specimens are quite similar in coloration.

This form is very closely allied to the typical eri/thronotos § by the upper tail- 

 coverts and feathers of the lower rump being of a dark bronzy violet with greyish 

 edges, instead of being of a more or less bright coppery bronze-colour. The under 

 tail-coverts are dull bluish black with greyish edges in the male, dark brownish grey 



* Gould says it is a native of " Trinidad and Guiana," and that lie received specimens from Trinidad 

 from Mr. Tucker of that island. Among the skins from the Gould collection in the British Museum are 

 only the Trinidad specimens, and they are given in the catalogue as the types. Moreover Gould's plate 

 represents a very large form with a very rich coppery rump and tail. 



t Dalmas and Simon consider that the name IVochilm iobari Gmelin, which Hartert accepted 

 {Tierreicli, Trochilidae, p. 55), is somewhat uncertain. Berlepsch is inclined to agree with them, and in 

 that case the oldest name to be used for this group is erythronoto.t, while ircltxi would be the name to be 

 used for the Tobago Island form. 



X We substitute 'J'rinidad. 



§ This must be restricted to Trinidad (and the Orinoco delta ?), as from Cumana the Tring Museum 

 has received (from Mr. Andrf ) a large series oifelieiue.
