This spécimen extends the known range of /. e. cxilis verv consi- 

 ilerablv. Hitherto no spécimen liad been obtained north of Bitv^e, 

 Cameroon where Mr. Batks seciired a number of spécimens now 

 in the National Collection. A différent race occurs in the Gold 

 Coast and one would hâve expected that tlie Lagos bird would 

 belong to this form. This, however, is not the case. I am, 

 verv donbtfiil whether the Gold Coast bird can be rightlv consi- 

 dered a sub-species of /. exilis exilis and it would not surprise me 

 to find a bird living in the Gold Coast side by side with willcocksi 

 which will link up D. exilis exilis and 1). exilis leona. Temporarily 

 D. c. willcocksi is best left where it was placed bv Ci.aidk Gkant 

 (Ibis, 19 15, p. 435) as a race of f>. exilis. 



I recognise six forms oi D. exilis. C. Grant, who reviewed this 

 group at length in the paper cited, recognised five races but I agrée 

 wnth Mr. W. L. Sci.ater that I. pyginacns Rkich. is best included 

 in this group. 



The six races are ; 



1 . — Indicator exilis exilis. 



Range. — Gaboon. Congo Mouth, East Belgian Congo (Ituri 

 Forest District), Cameroon, S. Nigeria, (Lagos District). 



Distinguishiug characters. — See Ibis, 19 15, p. 434. 



2. — Indicator exilis pygmaeus. 



Indicator pygtnaetis Rchw, J. f. O., 1892, pp. 24, 132 : Bukoba, 

 Victoria Nvanza. 



Range. — Bahr-el-Ghazal and Uganda. 



Distinguishing characters. — Size large, wing 73-80 mm. other- 

 wise similar to /. exilis exilis. As pointed ont bv Scl.^ter and 

 Praed {fbis, 1919, p. 640) /. e. pygmaeus combines the heavilv- 

 striped back of the exilis group with the larger size of the ininor 

 group, and appears to form a link between them.
