The evidence now before me tends to show that it is a resident 

 on the inland waters of Formosa. This fact I could not at first 

 reconcile with the notion that in China it was a migrant, repair- 

 ing to the high latitudes of Amoorland to breed. The Chinese, 

 however, declare that such is not the case with all individuals 

 of this species, for many pairs are known to breed regularly in 

 the lakes of Central China. The same habits obtain in its con- 

 gener, the Aix sponsa of America. The Summer-Uuck is said 

 to be a resident and to breed throughout the United States, even 

 in the most southerly of them, as also in the West India islands. 

 Those, then, that belong, so to speak, to the north would be 

 driven down by the freezing of the waters in their accustomed 

 haunts, and they merely shift southward in quest of open water 

 wherein they may seek their daily food. This explains one 

 part of the case in point ; the other, with regard to an inland 

 Duck finding its way to an island and settling down therein, 

 I leave open to theorizers. 



Megalama nuchalis, Gould. The immature bird has no tinge 

 of blue on the wings. Its back is dull green and devoid of the 

 yellow wash ; and the fire-tipped feathers of the back of the neck 

 are wanting. The yellow on the throat is paler, and the large 

 bright red spot of the lower neck is represented by only a few 

 light specks. Bill lighter and browner, with an ochreous edge 

 to the base of the lower mandibles. This species belongs to the 

 subgenus Cyanops. 



Dendrocitta sinensis, var. formosce. In the young bird the 

 blue grey of the head, hind neck, and rump is much sullied and 

 mixed with the liver-brown colour of the back. Several of the 

 tertiary quills are tipped with the same ; and the smoke-grey of 

 the under neck and breast is also strongly tinged with liver- 

 brown. The tail is ashy grey for the greater part of its length. 



Corvus colonorum. An adult. Agrees well with the charac- 

 ters already given of the species. 



Urocissa caruJea. l*^ull-grown young. Head and neck a dull 

 blackish, a few of the occipital feathers being tipj)ed with violet. 

 (Darwin again !) Upper parts much as in the adult, but duller 

 and swamped with smoke-grey on the back and rump. White 

 ti[)s to wings and tail washed with buff. Under parts smoke-
