offices that I have been able to procure the species that I have 
acquired since leaving Formosa. With the birds noted in the 
commencement of this paper I received from Formosa a Micro - 
nisus, which answers well to Dr. Jerdon’s description of the 
male M. virgatus ; but as I do not know the species, I cannot 
say with confidence that it is that bird. It was shot about the 
end of March 1866. 
On the 11th of May Captain Ebert, of the British schooner 
‘ Pearl/ brought me an adult Micronisus soloensis , which flew 
on board his vessel a few days before at the Pescadores. Its cere 
and legs are bright orange; its claws are black. It has the 
spotless cream-white axillaries. Its tarsi and toes are short and 
thick, as compared with those of the supposed M. virgatus. 
From its occurring at the Pescadores we are justified in adding it 
to the Formosan list. 
Two adult specimens of Gorsachius goisagi were also received: 
one is marked with more vivid chestnut than the other. They 
correspond with Bonaparte’s description of the species in his 
‘ Conspectus.’ The crest of the adult in summer dress is long, 
broad feathers, and similar in 
and composed of several rather 
style to that of But or ides javanica. In winter the crest seems 
to fall, leaving the head smooth and plain chestnut, instead of 
being capped and crested with cinereous-black plumes. This 
seasonal change is the chief cause for the confusion in determin¬ 
ing the species. The young bird described in the c Conspectus ’ 
would appear to be this species in winter dress. The true 
fledged nestling I have already described [supra, p. 123] from v / 
a pair that I kept alive at Takow. It is a species of the jungly 
interior, and occurs rarely on the plains. 
I think I must have been wrong in referring the Turnix 
rostrata (Ibis, 1865, p. 543) to the T. dussumieri division of 
Jerdon and Blyth. I have lately received two or three more 
males, similar to the first j one I got with the chicks. I have 
also some from the same locality, which I take to be females. 
They have a much deeper bill, which varies in length, depth, 
and even somewhat in form in individuals. Their forehead, 
cheeks, and throat are black, speckled with white, and they are
