Trogon Diardii. Temm., PI. Col. 54
T h e islands of Sumatra and Borneo constitute the native habitat of this beautiful species, which has been
dedicated to the memory of an intelligent French naturalist, who in the flower of his youth fell a sacrifice to
the unhealthy climate of the East. His name is associated in most of his zoological pursuits with that of the
son-in-law of the illustrious Cuvier, the intelligent and zealous Duvaucel.
Like Trogon Temminckii it possesses a nuchal band of rose pink, a feature not to be found in any other
than these two species.
The general contour of Trogon Diardii with its robust bill indicates it to be a bird of considerable power
and strength ; in these particulars it exceeds Trogon Temminckii, from which it also differs in the markings
of the three outer tail-feathers, in the total absence of the white pectoral band, and in the colouring of the
bare skin round the eyes.
It is the only species yet discovered in the Old World exhibiting any tendency to the barred markings of
the three outer tail-feathers, a character so frequently observed in the members of this family inhabiting the
new continent: in this instance the white feathers of the tail are covered with fine marbled markings rather
than with decided bars.
