242 ME. W. P. PYCEAFT ON THE 



Pt. ventralis. — Outer branch distinct, arising rather below the summit of the shoulder. 

 Median broad, terminating at a jioint corresponding with a line drawn through the carina 

 sterni at its middle. Inner branch broad, arising about halfway down the inner side of 

 the median branch. Nowhere sharply defined on the breast, but very distinct on the 

 abdomen. 



Pt. alaris : — 



Bemiges. — Metacarpo-digitals 11. Cubitals 18. 

 Tectrlces : — 



T. majores. — Coverts 1-5 of the dorsal surface longest, 6 slightly shorter than 5, 7 

 equal in length to 5. 



T. medice. — Damaged. 



T. minores. — Three rows. All showing an abrupt break in the length of the feathers in 

 each row. 1-5 always considerably the longest. 



Pt.fcmoralls. — Fcmoro-crural band terminating some distance below the knee. 



Pt. cruraUs. — Continued downwards over the acrotarsium on to the acropodium, termi- 

 nating behind the ungual phalanx, the base of which is clothed by scutes. The feathers 

 on the acrotarsium and acropodium very long, half concealing the claws. Planta bare in 

 region of tarsal joint only. 



Tlropyglmn. — In the form of an elongated cone, slightly swollen at the base. 



All the tracts are very narrow, but the feathers are of great length ; a humeral feather 

 measured 8 in. from lower umbilicus to tip, and one from the median branch of the 

 pt. ventralis 7 in. 



c OPS LEUCOTIS, Temm. 

 Pt. capitis : — 



Fronto-parietal area. — Feathers of the " ear "-tufts or "horns" in 2 longi- 

 tudinal rows of about 5 feathers in each. Their massed bases are surrounded by an 

 apterium, except anteriorly, where they merge with the broad band of feathers occu- 

 pying the median line of the head, thus tending to form short brandies to this band. 



Loreal area. — Moderately well defined, crescentic in form, the upper limb longest 

 and terminating above the region of the middle of the eye. Feathers of great length. 



Circumaural are a. — The preaural fold feebly developed, not forming an oper- 

 culum. A double row of feathers runs along its free edge, the bases of which form a 

 " rim " ; in front of this is a single row set in an apterium, as in Asio accipitrinus (p. 229). 



The bases of the feathers along the free edge of the postaural fold also form a "rim," 

 as in Asio &c. 



Interramal area. — Very wide posteriorly, merging with the mandibular area 

 from the gape backwards, rapidly contracting on the upper part of the neck, where it 

 becomes the pt. colli ventralis. 



R a m a 1 are a. — Broad, extending backwards beyond the end of the mandible. 



Lateral cervical apterium terminating at the base of the lower half of the circumaural 

 fold (PI. 26).
