This species is very similar in coloration to the South 

 African H. albigularis, Strickland (Jard. " Contrih. to 

 Ornith.," 18 i9, p. 17 — 4 with plate), but conspicuously 

 smaller, Strickland's dimensions being — whole length 

 7 in., wing 5 in. 2 lines, median rectrices 2 in., outer 

 ditto 3 in. 4 lines, so that the closed wing in the 

 Abyssinian bird is nearly an inch shorter. The pectoral 

 band also is imperfect in all the specimens I have been 

 able to examine. That the northern and southern species 

 are distinguishable is certain, and they are correctly 

 separated by Von Heuglin in his new work, but it is 

 equally clear that it is a mistake to apply Strickland's 

 name to the north-eastern race, since Strickland's mea- 

 surements and description are unquestionably those of 

 the southern form, and he particularly mentions that one 

 of the two specimens in his possession came from South 

 Africa. He discriminates the^ species from H. rufifrons of 

 Vieillot founded on Le Vaillant's figure of the Hirondelle
