XL. — On a new African Species of the Genus Zosterops. 

 By Th. von Heuglin*. 



(Plate XIIL) 



The genus Zoster-ops (a very circumscribed and very distinct one, 

 though not very rich in species) is found over nearly the whole of 

 Africa, in Madagascar, Australia, some parts of Northern Asia, 

 and in the Southern Indian Islands. I discovered a new species 

 in the high mountainous districts of Abyssinia, easily to be 

 distinguished by its very large eyes and eye-rings, and by its 

 breast and upper abdomen being of a pure grey. In my " List 

 of N.E. African Birds," printed in the * Transactions of the 

 Vienna Academy,' I have enumerated this new species under 

 the name of Z. euryophthalma, but now I prefer changing this 

 name into 



Zosterops poliogastra. (PI. XIII.) 



Supra virescenti-flava ; superciliis gutture et subcaudalibus sul- 

 phureis; pectore et epigastrio obsolete cinereis; abdomine 

 medio pallidiore ; remigibus et rectricibus fuliginosis, extus 

 virescenti-flavo marginatis, illis intus basin versus albidis ; 

 subalaribus albis, flexuram al?e versus virescente tinctis ; 

 tectricibus caudse superioribus fere totis flavis; macula 

 nigra inter oculum et rictum ; regione parotica viridi-nigri- 

 cante ; annulo periophthalmico nitide sericeo-albo ; tibiis 

 griseis, flavescente tinctis ; rostro nigerrimo ; pedibus plum- 

 beis ; iride brunnea. 

 Long. 4" 3"'; rostr. a fr. 4'"; al. 2" 5'"; caud. 1" 9"'; tars. 8'". 



The male is a little more brightly coloured than the female. 

 The first primary is 2" shorter than the second, third, and fourth, 

 which are the longest. This pretty species lives on the high- 

 lands of Abyssinia ; I found it there in the month of February 

 and March in wooded districts, on Euphorbiie and olive-trees, at 

 an elevation of 10-11,000 feet.
