544 Mr. R. Shelford on some 



metacarpo-digital has not yet pushed through, and, as there 

 is no carpal diastema, this feather looks as if it belonged 

 to the cubital series. Nos. 3, 4, & 5 are the longest. 



Cubit als. — Thirteen can be distinguished ; they decrease 

 in size proximally. Only the sheaths of Nos. 1 to 7 have 

 appeared, while of Nos. 8-13 not even these are to be seen. 



Tectrices : — 



T. majores. — Well developed on the dorsal surface ; on 

 the manus there are none ventrally, on the cubitus 12 weak 

 feathers. 



T. medice. — Nos. 1 & 2 (dorsal) are absent on the manus, 

 while ventrally 9, 10, and 11 only occur. On the cubitus 

 they are well developed dorsally, but ventrally are absent. 



T. minores. — On the manus dorsally one row (Nos. 4-11), 

 ventrally only one is present (No. 2). On the cubitus the 

 series begins with two rows and proximally widens out to 

 five, the second, third, fourth, and fifth rows terminating 

 abruptly and leaving a bald patch just above the elbow. On 

 the ventral surface there are none. 



T. marginales . — On the manus there are two rows on the 

 dorsal, and two on the ventral surface, one row of each series 

 being on the pre-axial border. On the cubitus, dorsally, 

 the series begins with eight or nine rows : at one point they 

 do not reach the pre-axial border of the patagium ; ventrally 

 there are three rows. 



Parapteron is singularly well marked ; it is continuous 

 with the T. majores media and minores. 



Hypopteron. — Non-existent. 



A carpal remex is present. 



Ala spuria with all the coverts well developed and con- 

 tinuous with the coverts of the cubitus. 



Pt. caudalis. — Rectrices with the dorsal and ventral 

 coverts developed. 



The foot has now assumed the definitive shape, the toes 

 being proportionally larger, the planta broader, and the 

 heel less prominent. The ventral scutes have not yet 

 appeared. 



Dimensions. — Total length (from tip of beak to base of
