 Plwtodilus is intermediate. The latter genus has the pecu- 

 liarity that the last digit has only four phalanges instead 

 of five, the two basal ones being fused. 



The number of cervical vertebrae does not appear to vary.

I have found fourteen in Strix, Photodilus, Ketupa, and 

 other genera which I have examined. In Bubo bcngalensis 

 the ring of the atlas is incomplete above ; the significance of 

 the occurrence of this same deficiency in Pandiou- is largely 

 lost, owing to the fact that Cariama is similarly characterised. 

 The haemapophyses in Ketupa javanensis commence as 

 single processes on Cll, and extend to D3 ; on CIO is a
