'2. Throat alwaj^s black in the male, in the female 

 whitish heavily striped with black ; crown 



very slightly spotted T. h. hirsiitum. 



Throat never black, always whitish streaked 

 wiih black. 



3. Less heavily marked with black on the ab- 



domen ; crown of female very slightly 



spotted with yellow T. h, hybridum. 



More heavily spotted on the underparts ; 

 crown of the female thickly spotted with 

 yellow T.h. ansorgii. 



4. Spotting on the abdomen black and clearly 



marked T. h. flavipunctatiim. 



Spotting on the abdomen brownish and in- 

 distinct T. h. angolense. 



TricholaBma leucomelan namaqua, subsp.nov. 



Closely resembling T. I. leucomelan, but tvith the under- 

 parts thickly spotted with oval spots o£ black. Size approxi- 

 mately the same as the typical form. 



Type. A male from Klipfontein, Little Namaqualand 

 (3100 ft.), 13 July, 1903, collected by 0. H. B. Grant. 

 Brit. Mus. Keg. No. 1905/12/29/455. 



Two other examples (females) also collected by Mr. Grant 

 at the same place, and a female from Springbok, also in 

 Little Namaqualand, collected by Mr. Chas. Reid, 30 August, 

 1902, all show the same character. 



A series from Deelfontein^ Cape Province, have distinct 

 traces of the spots, but are intermediate between the birds 

 from the Transvaal, Damaraland, and Angola, with pure 

 unspotted underparts, and the Namaqualand birds. 



I have also seen an example of this form, now in the 

 South African Museum, from Clanwilliam in the western 

 part of the Cape Province. 



Micropus caflFer ansorgei, subsp. nov. 



DescrijDtion. Closely resembling M. c. caffer and M. c. 

 streubeli, but distinguished by the darker colour of the 

 crown and head, which is almost as dark as the back, 

 and not distinctly brown and contrasting with the back
