definitcK with diiskx and white; tlu' throat is white, with an obsolete 

 dusky suhnuilar stripe; tlie lowt-r parts, exccjit the dusky sides, flanks, 

 and uj^per breast, are also white, with practically none of the dusky 

 mottling of the adult. "Iris pale brown amber; l)ill brownish, with 

 lower mandible whitish, except at base." 



2. Podilymbus podiceps (Linnaeus). 



Four specimens: (ircat Inagua (Mathewtown). 



The single adult has the throat black, with a few white-tipped 

 and wholly white feathers. The young birds are in natal plumage. 



3. Phalacrocorax vigua mexicanus (Brandt). 

 One specimen: W'atlings Island. 



This individual is completing a moult, which invoKes the remiges 

 and rectrices, as well as the feathers of the head and neck, the light- 

 colored feathers being replaced by darker. Hence I infer that it is 

 an immature bird moulting into adult plumage, the under parts 

 having already become deep black. 



It is surely odd that this bird has not been certainly detected 

 on any of the other islands in the group. 



4. Fregata aquila Linnaeus. 



One specimen: Great Inagua (Calefavor Pond, 6 miles east of 

 Alfred Sound). 



" Iris dark hazel." 



5. Phoenicopterus ruber Linna'us. 



One specimen: Great Inagua (Mathewtown). 



This individual has numerous black feathers along the cubital edge, 

 also dusky ones on the head and neck — doubtless remains of the 

 immature dress. 



6. Dichromanassa rufescens (Gmelin). 



Six specimens: Great Inagua (Calefavor Pond, 6 miles east of 

 Alfred Sound). 



Of the four adults, two are in the white phase and two in the blue, 

 one of the latter, however, showing a number of white feathers on 

 the breast and abdomen — a condition somewhat unusual in this 

 species, but not unknown. The two young birds, whose heads are 

 still thickly covered with the natal down, are also in the white phase. 



7. Hydranassa tricolor ruficollis (Gosse). 



Two specimens: Great Inagua (Alfred Sound; Calefavor Pond, 

 6 miles east).
