250 MR. W. P. PTCRAFT ON THE 



the intersca]iular region, very short, terminating a short distance from the free end of 

 the scaj)ula. 



The arms of the lumhar fork represeated hy a single row of feathers arising over the 

 anterior end of the ilium and which, crossing over the free end of the scapula, terminate 

 on the axillary memhr'ane. The stem of this portion very distinct ; its free end is bifid, 

 and terminates some distance from the oil-gland. 



Pt. ventralis. — Outer branch feebly developed, represented by a single row of feathers ; 

 median liranch broad, short, not extending beyond the middle of the sternum, the 

 recurved branch or " hook " very slender ; inner branch, arising in the middle region of 

 the furculum, follows the course of the clavicle and the carina, tlien turns inwards and 

 upwards to the thigh, whence it takes an almost straight course backwards to join its 

 fellow of the opposite side in front of the cloacal aperture. 



Pt. femoralis. — Pemoro-crural band terminating at the knee-joint. 



Pt. criiralis. — Feathers on the acrotarsium short. Planta bare. Acro[)odium covered 

 by numerous warty protuberances, each of which bears a degenerate feather ; little more 

 than the shaft, with perhaps — here and there — one or two rami, remaining ; radii absent. 

 Filoplumes absent. The base of the ungual j)halanx clothed with scales. 



Pt. alaris : — 



Bemiges. — No carpal diastema, the space between the metacarj)al and cubital 

 remiges being very much less than that separating the individual cubital remiges. 

 Tectrices -. — 



T. mujores. — The major coverts on the dorsal sui'face gradually increasing in length 

 from 1-5. This last the longest ; 6th shorter than 5th. 



T. mediae. — 1-5 gradually increasing in length, but the 5th abruptly longer than 1-4. 

 6th about as long as 4th. The 5th feather more closely bound to its covert — 5th major 

 covert — than the remaining feathers to their respective coverts. 



T. minores (row no. 1). — Covert 5 abru2)tly long(>r than 1-4, but of the same length as 6. 

 Disproportion in the length of the coverts of this group, above the 1st row, less marked. 



Mhmivphotheca. — Cere very short antero-posteriorly, much inflated, forming two 

 pisiform swellings on each side of the culmen. Aperture of the external naves circular, 

 dkected more forwards than outwards. Rhamphotheca compressed. 



Podotheca. — Claws short, very little curved. 



TJropygium. — Napiform. 



Carine noctua, Scop. 



Pt. capitis. — Fronto-parietal and occipital areas densely feathered. 



Loreal area indistinct. 



Interramal area expanded to join the ramal area on either side, from tlie level 

 of the gape backwards. 



Apt. colli laterale terminating at the level of the posterior limb of the external 

 aperture of the ear. 



Pi. colli dorsalis borne on a deep vertical fold ; no lateral folds.
