near the coast or up the narrow canons. One was taken at Ka- 

 huku December 31, and two were shot in the vicinitj' of Waima- 

 nalo December 23. Length, 25 ; wing, 12.57; bill, 3.19; tarsus, 3; 

 mid-toe and claw, 3.57. This bird is found on all the islands. 



Order PALUDICOL^. Family Rallid^. 



Gallinula sandvicensis, Street. Alae.

 These birds are common in the tule swamps, kalo patches and 

 fish ponds all over the island. The specimens taken show a de- 

 cidedly red tarsus. 



Order LIMICOD-E. Family Scolopacidse. 



248. Calidris arenaria, Linn. Hunakai. 

 Sanderling. 

 The Sanderling is by no means an unconunon bird here diir- 

 iug the winter months. On December 21 six were observed during 

 one afternoon along the sandy northern shore of the island, in the

 Wandering Tatler.

 short of wonderful. They know perfedtly well the rhythm of the 

 sea, and just how many big heavy waves will come pounding over 

 their rocks before there is a lull ; this they show b}' running far 

 down on the rocks after the third wave, knowing that the fourth 

 will be smaller and not large enough to knock them from their 

 new feeding ground. They also know perfe(5lly well if the in- 

 coming wave is going to break or merely swell past them, their 

 judgment in this matter being better than my own, although I
