alone amongst the Gallinze ; but neither in Meleagris nor in any of 
the Alectoropods do any traces of the upper wing-coverts exist. In 
some respects the Peristeropod Gallinee, represented by Yalegalla 
(fig. 13 a) and by Craz (fig. 13), stand nearest of the Gallinze to the 
Accipitres; while Numida is hardly more removed.

In the Peristeropods we find the commencement of a modification 
that is carried to a much greater length in other Galline birds, as well 
as in a large number of forms that have yet to be noticed. This 
consists in the increased prominence of distal overlap in the proximal. 
third of the cubital area. In Craw (fig. 13), for instance, it will be 
noticed that the distal overlap, whose commencement is indicated by 
the small cross, extends into the middle area in the case of the lowest 
tow. The distal overlap at C is another noteworthy feature, as it 
has not yet been observed in any of the Gallinz except the Peri- 
steropods. ] 
Taking the evidence afforded by the mode of imbrication of the 
wing-coverts alone, it is near to the Peristeropods, and not near to
