No. 3-21. ? Jan., Calama, 3. viii. lODT.— Wing 85; tail 38 ; bill 10 mm. 

 " Iris bi-own or blackish, fuet pale grey, bill blaok, below grey." 

 Specimens I'rom the Rio Madeira (Calama, Borba) and Manaijs (= Barra do Rio 

 NeTo) are rather more rut'escent brown above than a series from Cayenne, British 

 GnUina, and Marabitanas (npper Rio Negro), while others from the Jurmi and 

 Javarri Rivers, and from Peru (Chuchurras, Ilnanuco) have the upper parts paler, 

 more olivaceons. The latter ajiparently represent G. hircicauda minor Tacz.,* 

 though the differences in size do not prove to be constant. A larger series is 

 required to establish the geographical races of G. bre^imtula.

Similar to G. m. mficdaria of Cayenne and British Guiana, but wing decidedly, 

 tail slightly longer; sides and flanks very much paler, dull ochreous yellow with 

 an olive tinge (instead of deep ochraceons).

 berlepschi Snethl.-Wing 90 ; tail 37 ; tars. 37 ; bill 19 mm. 



This form had been separated by Miss Snethlage nnder the preoccupied name 

 G. m. bcrli'pschi. I have examined the original example from Ourem, and found it 

 perfectly identical with Natterer's bird. The female from Calama, althongii 

 immature, shows the same differences. In a series of nine specimens of G. m. 

 macularia from Cayenne and British Guiana the wing varies from 81 to 8(), the tail 

 from 20 to 3i mm. ; the sides and flanks are invariably deei) ochraceous. 



I suspect that the birds from Loretoyacu t and biuitos,^ North Peru, will also 

 turn out to belong to G. m. dilata, unless they be referable to G.//dviirntri.f Scl. § 

 The latter species, of which I have seen two specimens, the type and another from 

 Sarayac.-u, Eastern Ecuador, in the British Museum, differs from G. m. macularia 

 and G. m. ililuta by lacking the ochreous yellow apical spots to the upper wing- 

 coverts, and the ochreous edges to the outer primaries and the outermost bastard 

 quill ; the cheeks and ear-coverts are uniform slaty blackish ; the tail is russet- 

 brown (instead of brownish olive), the chest deep ochraceons buff like tlie sides 

 (instead of white) ; furthermore, there is no orange rim round the eye nor any trace 

 of the black maxillary stripe, etc. In the amount of black spotting on the breast, 

 as well as in the dark slate-grey cap, it agrees with the macularia gronp.
