■^ 00. Oriolus laetior .Shaiiiu.

 " Ifis blood-red, feet bluish grey, bill pinkish red." This oriole has been mixed up 

 with 0. bmchi/rhi/tirhus for a long time. It differs from the latter, of wliieh I kuow 

 K])ecimeus from Sierra Leone aud Liberia ouly, iu the followiu;;- ejiaraeters : — The 

 back is lighter yellowish green ; the yellow collar wider and more spread over 

 the back, the lesser upper wing-coverts are golden-yellow, not olive-green as iu 

 O. bnirlnjHiiinrhus; the tail aud wings are lighter aud less tinged with olive. 8harpe 

 (in Hull. B. O. Club, uo. 4s, November 1897) described this form as dirteriug from 

 (). brarkijilqinchus "in being smaller, aud liaving a conspicuous yellow collar, the 

 yellow also being spread over the mantle." Tlie smaller size, however, attributed 

 to this form, is uot apparent iu the specimens before me. O. brachjrhi/iirhus has 

 also a yellow collar, but it is less clear aud narrower. Oriolus laetior differs from 

 <>. If r cat K s a,ud 0. larmtm rolU'ti m being smaller, having a smaller white alar 

 speculum, the conspicuous golden yellow shoulder, and iu liaving the outer edges of 

 the secondaries and greater wing-coverts grey. The presence of an alar speculum 

 (the tips of the primary coverts being white), the yellow least wiug-coverts and 

 grey edges on the wing, sejmrate U. laetior also at once from 0. ^/igripenin.'s.

 " Jris almost white with faint yellow tinge : bill and feet black." The head in this 

 species is not steel-blue iu any Congo s])ecimen before me, nor on fig. 'Z ]j1. Vll 

 Vat. B. Brit. Mus. v. XIIL These figures are not very accurate, and do uot fully 

 agree with nature, nor .with the descriptions (pp. 172, 173). L. ijlaiwocircns is very 

 closely allied to the Senegambian L. splendidus, aud perhaps only snbspecifically 

 separable.

The four skins before me agree fully with the description, except thai theycwff/'o- 

 do uot differ from the males except in their smaller size, the wing being aboul 

 5 mm. shorter. The birds described as the females by Reicheuow (with a whitish 

 belly and under tail-coverts) may possibly be immature. Dr. Ausorge's birds are 

 l)robably not sexed wrongly, such mistakes occurring very seldom in his collections, 

 and their smaller size makes an error iui{)robable.
