FEK. 1897. EAST AFRICAN COLLKCTION OF BIRDS ELLIOT. 59 







sight this bird seemed to answer the description of Tinnunculus 

 arthuri, Gurney, the unique type of which is in the Norwich 

 Museum, but on sending the specimens to J. H. Gurney to have 

 them compared with the types, he replied that they were " larger 

 than T. arthuri, a good deal more rufous on the breast and belly, 

 and had not the conspicuously barred sides and flanks, which are 

 the chief characteristics of the bird in the Norwich Museum." 

 The species may be described as follows: 



Male. Upper parts light rufous, the head and nape streaked 

 with narrow black lines; back and wings barred narrowly with 

 black. Rump barred like the back, and upper tail coverts ash- 

 gray, barred with black and tipped, with light rufous. Primaries 

 black edged with light buff. Under-wing coverts buff with a few 

 short narrow black lines. Throat buffy white; rest of under parts 

 light rufous or rich buff, darkest on breast, narrowly streaked with 

 black on breast, abdomen,' flanks and thighs. Crissum and under 

 tail coverts pale buff, immaculate. Tail ash-gray with seven bars 

 of black, the subterminal on all but the outermost being in width 

 nearly one-fifth the length of the feathers and tipped narrowly on 

 the central pair with rufous, broadly on the others with buffy 

 white. The outermost feather is buffy white barred with black. 

 The tail therefore is darkest in the center, growing lighter to- 

 wards the outer feather. Bill pale blue. Legs and feet yellow. 

 Total length of skin 12.50 inches. Wing, 9.40. Tail, 6.20. 

 Culmen, along curve, .77. Tarsus, 1.50. 



Female. Resembles the male and is about the same size, but 

 has the upper part of the flanks narrowly barred with black, in 

 this respect leaning towards the characteristic markings of 

 T. arthuri. 



It gives me pleasure to call this species after Marshall Field, 

 Esq. , whose name this institution bears, and who is its most liberal 

 patron.

This fine vulture was not uncommon, coming about the camp 

 in considerable numbers, most of the individuals however, were 

 birds in immature plumage, those with white heads, thighs and
