As far as I can make out tlie geographic variations of this bird, 

 there are four recognizable forms, as follows : 



1. /S. a. aterrwvus. — Upper Guinea from Senegal to Togoland. 

 Grote ^^ suggests that Cameroon birds may be distinct by virtue of 

 larger size. I have seen no Cameroon material and can not form 

 an opinion on this matter, 



2. /S'. a. emihi. — The Sudan and southern Sahara from Asben, Lake 

 Chad, and the Shari Valley east through Darfur and Kordofan to 

 the valley of the Nile from Sennar to Lake Albert in L^ganda. 

 Hartert's form cryptostictus is identical with eniiiii, being based on 

 first-year birds with obsolescent mirrors on the primaries. Eniini 

 di Iters from typical aterrhnus in that the adults of tiie former lack 

 the mirrors on the primaries (present in juvenal and immature 

 birds). The former is said to be less violaceous above than ater'rl- 

 7/i'U8, but Lynes ^® finds no color difference between the two, and 

 I find in notatus nearly as much variation in this respect as in tlie 

 whole series examined from all parts of Africa. 



3. S. a. notatus.— 'YA-'iivea and Ethiopia (south to the southern 

 lakes region, but apparently not reaching Lakes Stefanie and 

 Kudolf). This form differs from the first two in liaving white 

 spots (usually) on the outermost pair of rectrices. 



4. S. g.. anchletae. — Angola. Characterized by broad white bars 

 on the outer tail feathers, and by large average size (wing about 

 115 millimeters). 



This species seems to be rather local and solitary, whicli accounts 

 for its apparent scarcity in collections. It lives in bushy thickets, 

 and being vocal only in the breeding season is an easy bird to miss. 

 Lynes found that in Darfur e?7iim molted in spring and early 

 summer, " * * * -md probably bred in autumn. * * * ?? This 

 probably is true for notatus in Ethiopia as well, for five of the six 

 males collected during April are molting the rectrices and remiges. 

 The two females are juvenal birds in Avorn plumage. The tail molt 

 is irregular, the variation in sequence of rectrix replacement being 

 so great as to make it impossible to work out any semblance of a 

 probable " normal " order. In the wings there are two centers of 

 ecdysis, the carpal joint and the third from the outermost primary.
