In his paper “On the Osteology of the Kagu,” Mr. Parker, in 
speaking of the nasal bone, says, “‘this part of the face is thoroughly 
Gruine in both the Eurypyga and the Kagu; the long open nasal 
fossa, so sharp above at the bifurcation of the nasals, gives a character 
to the face common to large groups of Gralle and Palmipeds.” Other- 
wise he does not employ this character in classification, as is evident 
when it is seen that he places the Kagu close to Psophia and the 
Rails, which are holorhinal birds. 
It may be mentioned that the external nasal process of the nasal 
bone is weak or obsolete in the Struthious birds.
