350 Mr. W. P. Pycraft on the 



whole I am inclined to regard tliis feather as the " remex/' 

 and not the " covert '' of Degen (2) . It is rooted in the very 

 small carpal diastema at the base of the first metacarpal 

 remex, and is a relatively large and well-developed feather, 

 being about as long as the cubital t. mediae. 



Parapteron (woodcut, fig. 1, p. 347, Pa.). — The parapteron 

 is composed of two rows of feathers, which, as usual, seem 

 to be serial with the t. majores and t. mediae. The feathers 

 along the post-axial margin are the longest. The third row 

 of smaller feathers iutercalcated between the post-axial rows 

 appears to be wanting. 



Hyjjopteron (PI. IX. fig. 3, //.).— Represented by five 

 moderately long and somewhat seraiplumous feathers arising 

 over the region of the dorsal border of the pectoral muscles, 

 and extending outwards on to the arm running along the 

 post-axial border, and not forward, as usual. 



Apteria : — 



Apterium capitis (PI. IX. fig. 1, Apt.cap.). — Represented 

 by a large space embracing almost the whole side of the 

 head, and is apparently of a light blue colour in life. The 

 surface of this space is broken up by the bristles previously 

 referred to, running down in front of and beneath the eye, a 

 few feathers round the opening of the external ear, and a 

 small patch of feathers between that orifice and the rham- 

 photheca of the mandible. 



Apt. spinale (PI. IX. fig. 1, Apt.sp.). — Extends from between 

 the shoulders to the region just above the posterior border 

 of the ilium. 



Apt. trunci laterale (PI. IX. figs. 1-3, Apt.t.lat.). — Arising 

 from the same region as the spinal apterium, from which it is 

 divided only by a nariow strip of the pt. spinalis, it extends 

 backwards to the femoral tract ; expanding meanwhile down- 

 wards, it embraces almost the whole side of the body. 



Apt. mesogastrcei (PL IX. figs. 2, 3, Apt.m.). — A somewhat 

 pyriform space extending from the region rather below the 

 middle of the breast to the cloacal aperture. 



Apt. al(£ superioris (PI. IX. fig. 1, Apt.a.sup.). — The small 

 space dividing the humeral from the wing-tract.
