238 ME. "W. P. PTCEAPT ON THE 



Bubo MACULosrs, Bp. 

 Ft. capitis : — 



iPronto-parietal area. — The feathers formmg the " ear "-tufts in a single 

 longitudinal row on the crown of the head, with a w ell-markcd apterium on either side. 



Loreal area. — Not sharply defined; vipper limb scarcely extending beyond the 

 anterior corner of the eyelid. 



Circumaural area. — The preaural fold is but feebly developed, and does not 

 Ibrm an operculum. It bears but a double row of feathers along its free margin, the 

 bases of which form a " rim " to the margin. 



The feathers of the postaural fold seated along the free edge of the upper part are, as 

 usual, all directed downwards, those of the lower part upwards, the two series meeting in 

 the middle of the fold. There is no " rim " to this fold. 



The peripheral disc-feathers apparently terminating below on the mandible, near the 

 base of the rhamphotheca. 



Ramal area. — Truncated posteriorly, not extending backwards to the proximal end 

 of the jaw. 



Interramal area. — Wide anteriorly, gently tapering joosteriorly to join the 

 ft. coll. ventralis. 



Apt. colli laterale. — Occupying the lower portion of the circumaural fold, and 

 running upwards and forwards behind a triangular patch of feathers clothing the upper 

 part of the Ibid, to cut off the row of feathers forming the " ear "-tufts from the rest of the 

 parietal area. 



Pt. colli dorsalis. — Vertical and lateral neck-folds of slight extent ; the posterior end 

 of the tract where it joins the^^. spinalis 4 feathers in width. 



Pt. spinalis. — Branches of the interscapular fork arising in the middle of the inter- 

 scapular region ; arms not extending to the free end of the scapiila. 



Branches of the lumbar fork arising about midway between the anterior end of the 

 ilium and the acetabular. Strongly developed, embracing the ends of the interscapular 

 fork, crossing the free end of the scapula, and terminating on the axillary membrane. 

 Stem strong, broad, bifurcated posteriorly, but not reaching the oil-gland. 



Pt. ventralis. — Outer branch broad, arising at the summit of the shoulder. 



Median branch not extending backwards beyond the level of the upper ^ of the carina 

 sterni. It is very sharply defined, with an upper trend at its free end. Its great 

 distinctness seems to cut it off from the recurved branch or " hook " characteristic of tliis 

 portion of the tract. 



Inner branch arises rather above the middle region of the clavicle, and follows the 

 covirse of that bone up to the carina sterni ; running along the upper end of this for a 

 short distance, it turns rapidly outwards and backwards to the region over the posterior 

 lateral process of the sternum ; from this point it runs backwards to join its fellow in 

 the middle line a short distance in front of the cloacal aperture. 



Pt. humtralis not running forwards to join the ft. ventralis. 



Pt. alaris. — Eemiges too abraded and broken to be of use for comparison as to 

 length, &c.
