86 BLACK-CROWNED BEE-EATER 
species dedicated to him; his name, therefore, is 
here adopted. 
Two specimens, now before us, establish the 
fact that the two elongated tail-feathers is either a 
sexual distinction, or a character of the adult plu- 
mage ; in one of these all the tail-feathers are 
perfectly even, while in the other the two middle 
end in lanceolate points, extending two inches and 
a half beyond the rest. 
The general plumage above, commencing from 
the lower part of the neck, is grass-green, which 
changes to blue slightly tinged with green on the 
rump, tail-covers, tail and tertial quills ; the nape 
is fulvous, tinged with green, and the crown deep 
black. On the front is a white band which passes 
round on each side, and forms a broad stripe over 
each eye. 
Total length, without the long tail-feathers, 8 
inches ; bill, from the front, 1 ; wings, 3i 2 o ; tail- 
feathers, from the base, 3\ 2 „ ; the middle pair 2^ 
beyond the rest.
