The female collected by Dr. KOCH at the Etna Bay is a very poor skin ; a white 

 superciliary stripe is well developed ; the under tailcoverts are wanting. It is remarkable, 

 that the type-specimen of E. caerulescens Temminck has been collected at the Lobo Bay. 



The four spécimens collected by Mr. LORENTZ hâve ail a well defined superciliary 

 stripe, also n°. 102, according to Mr. LORENTZ a maie, though its wing, 85 mm., more 

 approaches that of a female. The under tailcoverts in this spécimen are wanting; in n 05 . 93 and 

 266 the)/ are bluish grey, in n°. 82, where only a single under tailcovert is présent, this 

 feather is blackish with a whitish tip. The black band encircling the white throat is much 

 broader than in E. caerulescens. Wings 80 to 85 mm.
