_ There isa skull in the Paris Museum marked D. plumbeus, Mala- 
bar, Dusswmier. It measures as follows: Length, 22; beak, 134 5 
teeth-line, 12; width ee notch, 43; symphysis of the lower j jaw, bE 
inches ; teeth, 87-381, large ; beak elongated, higher than wide, — 
compressed in front; triangle extending rather before the teeth- 
lines. In the Anatomical Museum of the Jardine des Plantes is 
a skull of a foetal specimen of this species, from Malabar, which. 
is 12 inches long, with the beak 83 inches long, and 23 wide at 
the notch. The symphysis of the lower j jaw 1s 24 inches ional 
The bones are not united; the upper teeth are 36; they are as_ 
large as those of the adult skull, and all enclosed in a carti 
and very close together. From this skull it is evident that these-
