248 ME. W. P. PTCEAFT ON THE 



obliquely upwards ; the rest ai*e directed downwards ; heace the notch in the rim of the 

 fold (PL 27. figs. 5-6). 



The j)eripheral disc-feathers (p. 236) are continued downwards and inwards to meet in 

 the middle line a short distance behind the symphysis of the mandible. 



1 n t e r - r a m a 1 are a. — Cut into two by the meeting of the peripheral disc-feathers ; 

 the posterior portion somewhat triangular in form, its base planted against the confluent 

 peripheral disc-feathers, its tapering apex merging with tlie pt. colli nentralis. 



Apt. colli laterals terminating at the base of the circiimaural fold. 



Pt. colli dorsalis with considerable A'ertical and lateral neck-folds. The tract 

 decreasing rapidly in width from before backwards. 



Pt. sjniialis. — Interscapular fork bai'ely percejotible (PL 26). 



The lumbar fork, so far as my specimens are concerned, has the branches very feebly 

 developed and disconnected at their bases from the main stem. This last is continued 

 forwards so as nearly to join the interscapular fork (PI. 26). 



Pt. colli ventralis. — Very narrow at its upper end, where it joins the interramal area ; 

 sends off two branches at the middle of the neck to join the pt. ventralis at the shoulder. 



Pt. ventralis. — Outer branch well developed ; median strong, recurved ; inner strong, 

 not meeting its fellow in the middle line in front of the cloaca, but terminating over the 

 free end of the pubis. 



Pt. Immeralis. — Not continued forwards to join the pt. ventralis. 



Pt. alaris : — 

 Tectrices : — 



T. majores. — The dorsal coverts of the cubital remiges of uniform length, save the 6th, 

 which is much shorter than the coverts on either side. The same proportions appear to 

 obtain in the t. medice and t. minores. 



Pt.femoralis — Femoro-crural band turning sharply upwards to terminate over the 

 distal end of the femur. 



Pt. crtiralis. — Aerotarsium and acropodium densely and thickly feathered ; penultimate 

 phnlanx clothed with 3 scales. 



Phamphotheca. — Cere short, inflated, closely resembles that of Speotyto. 

 TJropyginm. — Small, napiform, but the pointed extremity very short, making the gland 

 almost triangular in form. 



Stjrnia ulula, Linn. 

 Pteryla caintis : — 



Interramal are a. — Expanding at the gape to join the ramal area. 



Apt. colli laterale. — Terminating on the jiostaural membrane. 



Pt. colli dorsalis. — With an oblique membranous fold, from the pt. colli dorsalis to 

 the centralis, similar to that of Asio, but more feebly developed. 



Pi. spinalis. — Interscapular fork barely perceptible ; the tract, which is broad, termi- 

 nating midway down the interscapular region. The posterior moiety of this tract has a 

 very broad anterior end, not differentiated into branches.
