THE HONEY-GUIDES 105 



the U. S. National Museum. The honey-guide egg, measuring 21.5 

 by 17 mm., agrees in size with the dimensions of eggs of /. variegatus.

Uncertainly recorded as a host in Uganda, 



Van Someren (1916, p. 234) records having found eggs of Indicator 

 variegatus in nests of this barbet in Uganda, but Jackson (1938, p. 734) 

 raises a doubt, as the barbet "bores a hole so small that neither of 

 the twolargerHoney-Guides could possibly get inside it to lay, nor could 

 the young birds when ready to fly get out of it." Inasmuch as the 

 eggs of /. variegatus are not certainly distinguishable from those of 

 I. minor, the record, unsupported by further details, cannot be ac- 

 cepted as satisfactory. 



Trachyphonus vaillantii vaillantii Ranzani. Levaillant's barbet.

 1821, (South Africa, ex Levaillant= southeastern Cape Province, fide 

 Vincent, BuU. British Ornith. Club, vol. 55, p. 94, 1935.) 



One record, not wholly satisfactory. 



A set of two eggs of this barbet with one egg of the variegated 

 honey-guidi was collected at Woodbush, Transvaal, December 3, 1920, 

 by the late H. W. BeU-Marley. This set is now in the collections of 

 the U. S. National Museum. The honey-guide egg measures 20 by 

 16 mm., as contrasted with the much larger barbet egg, 27 by 20 mm. 

 The identification of the parasite cannot be looked upon as more 

 than "probable." 



Campethera nubica nubica (Boddaert). Nubian woodpecker. 



Picus nubicus Boddaert, Tables des planches enlumin^ez d'histoire naturelle, 

 p. 41, 1783. (Nubia, based on Daubenton, Planches enlumin^es, pi. 667.) 



The Nubian woodpecker is definitely known as a host of the scaly- 

 throated honey-guide in central Kenya Colony. 



Jackson (1938, p. 734) writes that van Someren took a nestling of 

 the parasite from a nest of this woodpecker. In answer to my request 

 for fuller data van Someren kindly informs me that this was in July 

 at Ngong. 



J. G. Williams (in litt.) observed a fuUy fledged Indicator variegatus 

 being fed by a Nubian woodpecker at the Southern Uaso Nyiro River, 

 west of Lake Magadi, Kenya Colony, in May or June 1947.

 woodpecker.

One record, imfortunately without explicit locality.
