BIRDS OF HAWAIIAN ISLANDS. 



Measurements. 



Arenaria interpres (Laxx. ). 

 Turnstone. Akekekc. 



The native name here given is the same as that previously given for 

 the Sanderling (Calidris arenaria, Proc. U. S. jSTat. Mus., x, 18S7, p. 

 82), but the two birds sliould not be confounded, and "Akeke Kakio- 

 wai" may be the proper name for the last mentioned species. 



The two specimens sent appear to be young birds in winter plumage. 

 They were collected on the island of Niikau. 



Mr. Dole has already recorded this species from Kauai under the 

 name of Strepsilas interpres (Hawaiian Almanac, 1879, p. 51). 



Measurements. 



Himantopus knudseni Stejx. 

 (Proc. U.S. Nat. Mns., x, 1887, p. 81.) 



Two specimens from Niibau confirm the validity of this species. The 

 peculiar coloration of the tail alluded to in the original description is 

 also found in these, though less pronounced in No. 113463. The addi- 

 tional specimens, however, present another very strongly marked 

 character which 1 did not mention in describing the type specimen, 

 because most of the feathers in question were wanting, viz, that the 

 longest upper tail-coverts have the inner webs entirely black, and that 

 the down surrounding the uxopygial gland are blackish. In some of 

 the specimens of II. mexicanus the upper tail-coverts are more or less 

 suffused with light gray, but I have found nothing like the broad me- 

 dian black stripe covering the base of the tail in H. knudseni. 



The type specimen having a greenish black back is undoubtedly a 

 male, while the two Niihau lords appear to be females, having the 

 back brownish.
