aucl tie nortbeni (smaller — East African) forms of C. guttitralis, calling that 

 from East Africa C. ;/utt//ralis, that from Damaraland C. gutturalis (/amarensin. 

 The difference in the size of these two forms is apjiarently larger than that of 

 V. acik acik and ('. a. aeqiiatorialis, the wing being 75 — 58 in the southern, 

 ''I — "2 in the northern form. Prof. Ileichenow's name damarensis, however, 

 cannot be nsed, as I have alread}- (Ansorge's Under the Afr. Sun p. 351) named the 

 East African small form ('. giitttiralis inaestimata, restricting the name gutfiiralis 

 to the large southern form. As Linnaeus did not give the exact locality, his species 

 being taken from Bvhsona'Gri.mpereaH noirastre de Bresil, and this name being 

 afterwards used for southern birds, I, as the first author, who discussed the forms, 

 had the right to restrict the first name t/'ittitralis to any one of them, and it seemed 

 to me more natural to apply it to the southern larger form. 



A third closely allied form is C. giitt. safnrafior Rchw. from Angola.

In no. 1- <if vol. VII (18'.)9) Orn. Movber. Prof. Reichenow has published the 

 results of a careful study of the forms of Cinm/ris cliloroypgin auct., as far as 

 material was available to him. Mr. Rothschild and I have gone over the series in 

 the Tring Museum, and we found that it fully bears out the conclusions arrived at 

 by Prof. Reichenow. We have the following specimens of the three forms 

 recognized by Prof Reichenow.

The differences stated by Reichenow are easily recognizable, especially the 

 tyjiical form with its very short wing and pale abdomen is very distinct. There 

 is, however, a mistake in Reichenow's " key," the measurements of the two groups 

 under no. 2 being given as over 50 and under 50 mm., while it should clearly 

 be — as evident from the measurements given under no. 3 — over and under 5fi or 

 CO mm.
