BIRD8 OF KAUAI ISLAND, HAWAIIAX ARCHIPELAGO. 



Hawaiiau birds. This bird is larger ; has uo bristly thigh-feathers ; 

 upper tail-coverts buffy-graj-, barred and streaked with dusky, like the 

 ruiup ; under tail-coverts stieaked and barred ; axillaries and nnder 

 wing-coverts white, barred with dusky; and crown streaked with light 

 and dusky, without a mesial stripe. 



The bristly thigh-featbers of K.femoralis are quite characteristic, and 

 are not due to abrasion, as has been supposed by some authors, for they 

 are certainly i)resent in a quite young bird, collected by Mr. Charles H. 

 Townsend in Alaska, during the summer of 1885. 



Mr. Knudsen, at an earlier occasion, presented the Museum with two 

 specimens of this species, an addition to the Hawaiian fauna. In the 

 table of dimensions I have added the measurements of two other speci- 

 mens, including the type : 



Measurements. 



^Type. 



?Plegadis guarauna (Linn.). 

 Wliite faced Glossy Il)is. 



1766.- Scolopax guarauna Linn., S. N., I'Z ed., I, p. 212. — Plegudis g. Ridgway, Proc. 

 U. S. Nat. Mus., I, 1878, p. 163.— /<?., Water B. N. Am., I, p. 97 (1884). 



A young G-lossylbis, collected in Kauai, was received from Mr. Knud- 

 sen in 1872. It is No. 61258. Mr. R. Ridgway, referring to this speci- 

 men, says as follows (Water B. K Am., I, p. 98) : "A specimen from the 

 Sandwich Islands; we refer to this species somewhat doubtfully, it 

 being in immature plumage. It agrees strictly with American examples 

 of the same age in all respects wherein guarauna differs from falcinellus, 

 even to the reddish color of the bill, lores, and feet. Still, it is possible 

 that perfect adults may show differences from both forms." 



We are not aware that any other collector has obtained any Plegadia 

 in the Hawaiian group. 



Nycticorax nycticorax naevius (Bodd.). 



Black-crowued Night Herou. 



1783. — Ardea ncevia Boddaert, TabL PL EuL, p. 56.

1884. — Nycticorax griseus nwvius Ridgway, Water B. N. Am., I, p. 55. 



A nearly adult Night Herou and a younger bird, both from Kauai, 

 are in the Museum from Mr. Knudsen (Nos. 41951, 41952). However,
