This form differs from the preceding in having the black on the 

 breast extending over the bellj', leaving the flanks, vent, and under 

 tail-coverts slate-grey. The female also differs from that of the pro- 

 ceding form in having the rump, vent, and under tail-coverts inclined 

 to slate-grey. It is a slightly larger bird, the wing measuring 

 in the males -I'S to 4'4 iuches, in the females 4"3 to 4*2. 



The Trinidad Grey Ouzel is found in the island of Trinidad and 

 in Venezuela. It is supposed to be a resident.

In the adult male the general colour of the upper parts is slate- 

 grey, shading into dark slate on the head ; lores brown ; ear-coverts 

 dark slate-grey ; no trace of eye-stripe ; wings brown, the wing- 

 coverts, innermost secondaries, and unemarginated portions of 

 outer webs of quills slate-grey ; tail brown, the central feathers 

 and outside webs of the other tail-feathers slate-grey. Chin and 

 upper throat nearly white, streaked with nearly black ; rest of 

 underparts pale brownish grey, shading into nearly white on the 

 centre of the beUy ; under tail-coverts nearly white ; axillaries and 

 under wing-coverts pale brownish grey ; inner margin of quills 

 pale slate-grey. Bill bright yellow. Wing with the third, fourth, 

 and fifth primaries nearly equal and longest, second primary inter-

 wing 4-68 to 4-45 inches, tail 3-93 to 3-55, culmen 0-9, tarsus 1-25

The female is unknown. Young in first plumage have the usual 

 characteristics of the allied species in similar stages. 



The Puna Ouzel is only known from Puna Island, in the Gulf 

 of Guayaquil, off the coast of Ecuador. 



The British Museum does not possess an example of this species. 

 I have described the type in the Museum of the Smithsonian In- 

 stitution, and have examined a skin in the collection of Messrs. 

 Salvin and Godman, intermediate between young in fii-st plumage 

 and bird of the year.
