of the Dppcrside being about the same as iu X melanotis melanotis. Dimensions 

 hardly less than of N. tndauotis pi'isonatus, bnt the dusky black streaks on the 

 flanks are much narrower than in the latter. "Iris yellowish."' Wing c? 116 — 

 121 mm., ? 110—111 mm. 



Messrs. Baur & Adams discovered this species on Tower Island, where it was 

 also found abundantly by Harris' party. The Triiig Museum possesses the tj-jie 

 (which has been in spirits), and a good series collected by Baur's and Harris' 

 parties. 



0. Nesomimus melanotis bindloei Hidg. 



N. hindlnei Ridgway in Pruc. U.S. Xat Mm. XVII. p. 358. XIX. p. 492 (1894).

 'A mm. longer, the lesser wing-coverts with slightly lighter tips, ear-coverts more 

 uniformly black, moustachial line of spots on sides of throat less distinct, while on 

 the other hand there are generally some small black spots on the sides of the neck, 

 under the ear-coverts and sometimes even on the chest. Discovered by Baur it 

 Adams, and found to be common on Bindloe Island by our collecting party. 



The Tring Museum possesses the type and ten others from the Baur collection, 

 in addition to a good series of the new collection. 3 wing, 108 — 117 mm. ; ? wing,

Easily distinguished from X. melanoti.i by its smaller size, especially its 

 shorter and somewhat less curved bill, generally paler colour of the upperside and 

 more brownish, paler striped ear-coverts. A brownish shade across the chest is 

 visible in most specimens. Wing of c? ad. wing 111 — 113 mm., exposed culmen

Very closely allied to K. pan-ulus pamdtis of Albemarle, but above darker and 

 deeper brown than even the darkest ^V. parvulus parcnlu.s. The stripes on the sides 

 of the body are generally broader and darker. White spots on wing-coverts smaller.
