This bird is distinguished from D. angolensis by having 

 the blue of the head and nape extending on to the mantle 

 as in D. a. nandensis, and in not being sharply defined from 

 the mantle. The blue colour of the head and nape is not so 

 intense as in D. angolensis. In size it is about the same. 



From D. a. nandensis it differs in having the general colour 

 of the upper parts greyer, particularly the mantle, wiugs, and 

 tail. The head and nape are darker blue and lack the grey 

 wash of Z). a. nandensis. Moreover, this colour extends further 

 on to the mantle than in either of the specimens of D. a. 

 nandensis which I have examined, i. e. the type from Nandi 

 and the Congo Forest bird, obtained by the Ruwenzori 

 Expedition. The sides of the body and flanks are strongly 

 washed with french grey, of a more intense colour than 

 even in D. angolensis, which character is practically absent 

 in D. a. najulensis. 



In size D. a. grisescens is decidedly smaller than D. a. 

 nandensis, the wing measuring 82 mm., as compared with 

 87-90 mm. in the east African race. Reichenow considered 

 it a subspecies of D. senegalensis, but it has nothing to do 

 with this species. 



Culmen (exposed portion) 13 mm. ; wing 82; tail 61 (from 

 base of the middle tail-feathers) ; tarsus 24. Iris bright 

 blue.

When Shelley wrote volume ii. of the ' Birds of Africa/ 

 Zosterops stenocricota was known only from the type speci- 

 men, which had been procured by Dr. Preuss at Buea on the 

 lower slopes of Cameroon Mountain. Since then it had not 

 been obtained in that locality until Alexander procured the 

 small series enumerated above.
