36 Director' s Annual Report. 



under neck, under surface of body, mantle and wings, sooty black ; 

 ieet and tarsus yellowish brown ; webbs, yellow ; iris, dark brown. 



The "light ashy green" on the hind neck and upper part of 

 the interscapular region, which Mr. Rothschild speaks of in "Avi- 

 fauna of lyaysan," is presumably chara(5leristic of summer plumage, 

 as these winter specimens fail to show such coloring.

Order STEGANOPODES. Family Phaethontidse. 



113. Phaethon lepturus, Lacep. & Daud. Haakoae. 

 Red-billed Tropic Bird. 



Three times I have observ^ed these birds sailing about the 

 ridges of Waiolani mountain above Honolulu, at about 1000 feet 

 elevation. Few birds can excel the grace and ease of this bird's 

 flight among the cliffs of the mountains. This species occurs on 

 all the islands. 



Order ANSERES. Family Anatidse. 



143. Dafila acuta, Einn. Pintail. 

 December 23, I accepted the courteous invitation of the Hono- 

 lulu Gun Club to accompany them on a shoot over their preserv^es 

 in the vicinity of Waimanalo. Decoys were spread in the early 

 dawn and twenty ducks were secured. I am told this was an un- 

 usuall}' small bag for the club, being but three ducks to the man. 

 A large number of plover were taken, however, to make up the 

 deficiency. Sixteen of these ducks were of the above species. 

 The remaining four were the native Hawaiian duck. 



Anas wyvilliana, Sclater. 



This duck is fairly common on the island among the tule 

 swamps and ponds near the coast. Length, 18.50; wing, 9.67; 

 tail, 2.37; tarsus, 1.46; culmen, 2.12; its depth at nostrils, .61; 

 mid-toe and claw, 1.81. 



Order HERODIONES. Family Ardeidse. 



Nycticorax griseus, Wiggl. Auku. 



Black-crowned Night Heron. 



These are common about the marshes in the vicinity of Ka- 



huku. During the day they usually hide in dense clumps of trees
