In both these birds the quill-feathcrs are black, edged with white j 

 the three outer tail-feathers on each side black at their base and 

 broadly white at their tips; and the two middle tail-feathers tipped 

 with black, their remaining portion being of a chestnut brown, which 

 in Trog. erythrocephalus is deep, and in Trog. Malabaricus light.

The tail is considerably lengthened in the male, and its four middle 

 feathers are bronzed green on the upper surface, and deeply marked 

 with black at the tip ; the three outer feathers are white at the tip, 

 and barred to a great extent on their outer edges with alternate lines 

 of black and white, a marking which appears also, though less exten- 

 sively, on their inner edges, the remainder being black : in some spe- 

 cimens this marking of the tail is reduced to an irregular and minute 

 sort of dotting, in place of the bars. In the female the middle tail- 

 feathers are of a dull chestnut, tipped with black, and the three outer 

 feathers much resemble those of the male, but are less decidedly dot- 

 ted, assuming rather a freckled appearance. 



Mr. Bennett briefly recapitulated the facts and reason ing.s which 

 have from time to time been brought before the Society on the sub- 

 ject of the abdominal glands of the Monotremata, regarded by Meckel 

 and by Mr. Owen as mammary, and by M. GeoflVoy- Saint Hilaire 

 as connected with a peculiar function, to which, however, differ- 

 ent results have been attributed by that learned zoologist at various 

 times. The object of the recapitulation was to introduce an abstract 

 of a recent Memoir by M. Geoffroy-Saint-Hilaive, " On the structure 

 and use of the Monotrematic glands, and particularly on those glands 

 in the Cetacea." In this Memoir the author regards the mammary 

 glands of the Cetacea, so analogous in structure to those of Ornithu-
