side just behind the nostrils and runs backward into the cervical tract 

 almost parallel to those first described. The fourth complete row on 

 each side commences under the eye, near the angle of the mouth, and 

 alter running forward a little way curves up and back and runs par- 

 allel to the others into the cervical tract. There is another incomplete 

 row on each side, which begins about the middle of the upper eyelid 

 and runs down the back of the head behind the ear, but does not seem to 

 join in the cervical tract. The rows are closer together than in any of 

 the other genera and curve as shown in fig. 1. The upper cervical tract 

 is quite broad and is clearly and widely forked at the end. The dorsal

tract extends forw'ard from the oil gland, in a rather narrow band which 

 is forked in front and unites plainly with the cervical tract, thus inclos- 

 ing a diamond-shaped spinal space. There are on each side of this 

 fork a few scattered contour feathers, but they are not very evident. 

 The femoral tract is clearly defined, but is not peculiar in any way, 

 thougli on the femur between it and the dorsal tract there are many 

 scattered contour feathers. There are also a few such feathers on the 

 tibia, but there are none on the tarsus. The humeral tracts are strong 

 and extending clear across the shoulders unite with the ventral tracts. 

 The feathers on the chin and throat (fig. 2) aie widely separated and are 

 arranged in more or less longitudinal rows which converge in front to
