addition to this there are also, especially on the lower breast, 

 some transverse dark bars chiefly in the distal portion of the 

 feathers. On the abdomen these bars become more or less 

 faint or completely reduced. The whole pattern is rather 

 irregular and ne ver has the »herring-bone » appearance cha- 

 racteristic for choliba and some others. The under tail-coverts 

 are provided with more or less pronounced mesial streaks 

 but no bars. Toes and lower portion of tarsus to a varying 

 extent entirely naked.

 Vn, Gualea 4000—5000 f.; 1 (^ "/n, road to Gualea 6000 f.;

 comparatively dark with the upper back nearly black and 

 in three of the specimens only slightly mottled.

 These specimens agree on the whole quite well with Sclater's 

 description. The head is less uniform and shows subapical 

 rufous bars on almost all feathers. The amount of white above 

 the orbit is different in different specimens and as a rule more 

 or less spotted with darker. The feathers on the tarsi are 

 partly white partly rufous in a various degree in the different 

 specimens. The length of the wing is from 249 to 256 mm. 

 in the males, and 262 mm. in the female. It is possible that 

 these smaller measurements and the differences in colour 

 mentioned indicate a separate race, but considering the varia- 

 bihty often exhibited by owls we have not regarded it desir- 

 able to give any new name. 



Gisella Tiarrisi Cass. — 1 (^ '/lo? near Zambiza, about 

 8500 f. Consul Söderström remarks that this Owl is »very 

 rare». The length of wing is 142 mm. It is not recorded by 

 Brabourne and Chubb for Ecuador.
