From the above-mentioned localities it ranges southward into Natal and Caffraria, and westward to the Loango coast. 24. A M B L Y O S P I Z A U N I C O L O R. Amblyospiza unicolor, Fischer & Reichenow; Shelley, P.Z. S. 1881, p. 589. Mamboio. This is the most southern limit we can yet accord to this species. 25. FRINGILLARIA ORIENTALIS, sp. n. Very similar to F. major, Cab., but smaller, with the bill and legs slightly longer and stouter; the eyebrow and white central band on the crown broader and more distinctly marked. Total length 5*7 inches, culmen 0*55, wing 3*2, tail 3*1, tarsus 0*8. Mamboio. In m y opinion this is only one of three races of a single species ; but I haveTiere described it as a new species, as many ornithologists may prefer to consider it such. By the term race I intend to indicate that the form is so nearly allied to one or more others that, in my opinion, further research is sure to discover intermediate forms which may be placed as well with one as with the other. The three races are ;- 1. F. cabanisi, Reichenow, J. f. O. 1875, p. 233, pl. 2. figs. 2, 3. Hab. Cameroons. This race is only known to me by the description and plate I. c. 2. F. orientalis. Hab. Mamboio. 3. F. major, Cab. J. f. O. 1880, p. 349, pl. 2. fig. 2. Hab. Angola. As regards F. cabanisi, Bocage, Orn. Angola, p. 371, I have a specimen in m y own collection of this form from Caconda. It differs from the plate given by Dr. Cabanis (/. c.) in the central stripe on tbe crown being white, not grey, and in the feathers of the mantle being more striped and less scale-like, their dark centres generally extending quite to the tips of the feathers. 26. M I R A F R A TORRIDA, sp. n. (Plate XVII.) Upper parts rufous-brown, with dark central stripes to the feathers of the crown, nape, and greater portion of the back; rump and upper tail-coverts with obsolete shaft-stripes; some of the feathers of the mantle very partially edged with buff. Wings rufous, the coverts and secondaries edged with buff; median and greater coverts partially barred with black; secondaries somewhat similarly barred, and with a waved black line encircling each feather near the edge ; primaries browner, without black markings, and broadly edged externally and internally with rufous. Tail, two ceutre feathers rufous; outer tail-feathers, with the exception of an inner edging, and the outer |
