66 Mr. C. H. B. Grant on a Collection of 



b. ? imm. Lemek Valley, 6600 ft. Oct. 6. 



c. ? ad. Amala River, 5300 ft. Oct. 19. 

 All are somewhat worn. 



The young bird differs from the adult principally in its 

 smaller size and in being somewhat lighter above. 



Total length in flesh: ad. 43| & 40A inches; imm. 

 36f inches. Wing: ad. 630 & 605 mm.; imm. 555 mm. 



These three specimens agree Mell with the description of 

 this subspecies, and show the distinctive difference in the 

 lores and superciliaries when compared with the single 

 south African specimen before me of O. k. kori Burch., 

 the type-locality of which is " Junction of Orange and Vaal 

 Rivers, Griqualand " (c/. Burchell, Trav. i. 1822, p. 391). 



The wing in this south African bird measures 530 mm , 

 The bird is undoubtedly immature, and besides showing the 

 mottled lores and superciliaries as pointed out by Neu- 

 mann, is distinctly more sandy above than the immature 

 bird from the Amala River. 



[Adult. Irides yellow-brown or yellow, lower half pale 

 brown ; bill, upper mandible dark brown, lower greyish 

 white or black, base of lower mandible light horn ; legs 

 and toes dirty cream or dirty greenish white. 



Immature. Irides yellow ; bill, upper mandible dark 

 horn, lower whitish ; legs and toes dirty white. 



More commonly seen than the Stanley Bustard.] 



68. Threskiornis asthiopica. Sacred Ibis. 



Tantalus athiopicus Lath. Ind. Orn. 1790, p. 706: 

 ^Ethiopia ; probably Egypt, cf. Bruce, Trav. to Disc. Source 

 of Nile, vol. V. App. i. 1790, p. 172, pi. 35. 



a. S imm. Lake Naivasha, 6700 ft. Dec. 4. 



Totallength in flesh : 30^ inches. Wing : 382 mm. 



The single example is moulting into adult feathering on 

 the wings. 



This specimen matches very well the figure given by 

 Bruce. 



[Irides brown ; bill black ; legs and tors black. Quite 

 common.]
