Himantopus knudseni Stejn. 



Knudsen's Stilt. Aeo. 



The black mesial stripe on the rump and the broad black tips to the 

 tail-feathers are well developed in both examples sent. No. 116777 has 

 the entire fore neck mottled with black all across. The dimensions 

 agree well with those of previous specimens, though the wing is rather 

 longer and the tail shorter. The bill, however, is fully up to the stand- 

 ard, but No. 11G776 has a remarkably short tarsus. The characters of 

 the new species are thus pretty well established.
