Beddard *. In C. celebensis the ventral tract divides much 
lower down the neck, the pt. capitis is more sparse, the apt. 
colli lat. is (judging by the figure) more circumscribed, and, 
most important of all, the pt. spinalis is completely interrupted 
save for a few scattered feathers at the level of the junc¬ 
tion of the coracoid and scapula, thus approximating to 
the arrangement of the tract in the Stage 3 nestling of 
C. sinensis . It is impossible to regard the complete spinal 
tract as anything but the more primitive : this condition of 
the tract is exhibited by the trichoptile-clad embryo and 
nestling (Stage 2) of C. sinensis , whilst the adult is inter¬ 
mediate between them and the insular and more modified 
species C. celebensis; it would be interesting to see what 
place in this series would be taken by the young of the latter 
species.
