3«i THK FEATHKK-TUACTS OF SPIIKNURA BUOAD-BKNTI, 



wing ^f specimen A, there is a sign of them in the right 

 wing, being sufficiently distinct to be counted. 



The wing is eutaxic. 



Tectrices. — In spec. A the t. majores of the cubitals are 

 10, and well indicated, the t. mediae being 6. and 

 well marked, a lens being needed to see the t- 

 minores, t. marginales being not yet visible. 



The coverts of the under surface of the wing do not 

 yet show any sign of appearing. Tlie dorsal major coverts 

 of the primaries are not yet visible. 



There is no appearance of pt. spuria. In spec. B the 

 veins of pt. spuria are breaking from their sheaths, though 

 not so advanced as the covoi-ts, the major coverts of the 

 secondaries being more advanced than those of the primar- 

 ies. Only the innermost of the t. mediae is exposing its 

 vein. 



The pt. marginales are just showing- The four rows of 

 tectrices upon the under surface are well developed, but 

 just breaking from their slieaths. 



The carpal covert is equal to the t. minores of the cubi- 

 tals, being much further ahead of the primai-y medium 

 coverts in their development. 



In pt. spuria five strong feathers tak:^ part in the for- 

 mation. 



Parapteron is naked in spec A and B , in C there arc 

 two rows, each four feathers. 



Fig. 3 gives a lateral view of phase B. The veins 

 breaking from the follicles indicate the pale rufous and 

 grey colours that are in C and D. The plumage of C is 

 already rufous-tinted, as in the adult D, being brighter 

 upon the ear coverts than upon the head. The under- 

 surface is devoid of the lunations of the adult, and the 

 throat has a pale cream-coloured band across it. extending 

 outwards to the region below the eye- This prominent 

 mark does not appear on the adult D, its mark of the past. 



At this stage the tail coverts are well developed, and 

 more than half the length of the rectrices. In colour they 

 are almost as intense as in the adult. The broad outer
