Moreover, as Sphyra-picus has a hyoidean apparatus very much as we find it inthe majority of birds where the epibranchials are notcurled over the top of the skull as shown in Fig. 2 at c,the skin is not elevated along that region. In some birds,of course, as the condors, the head is destitute of feathers.The head-tract, as a rule, however, includes the head andthe lateral tracts of the neck, merging below into theventral and spinal tracts (Figs. 4 and 5). We may nextcompletely finish the plucking of our two specimens,closely observing the position of the feathers as wedeliberately remove them. Now it will be found thatwith some few, very few comparatively, birds a strip offeathers of uniform width run down the entire length ofthe back, but as a rule the greatest amount of variationexists in this particular.
