liKMAliKs. This remarkable little Duck is very dilb'rent from any other known species. In its .small 

 size, and, to a certain extent, the narrow bill, it is like the s]iecies of Qiierqiiriliiln, but its coloration calls 

 instantly to mind the Aiiasfiifviriiild from Florida, and the species (//. It'iivillicnw) from the Sandwich 

 l.slanils recently describeil by Mr. Selater. The specimen is marked as being a feninle, .so it is i)os.sil)lc 

 that the male may be more brilliant in ]iluiiiage. 



In addition to the characters given above, it may bo mentioned that there is a distinct indication of n 

 narrow, dusky, postocular .streak, and of a wider and less distinct loial .stripe, thus .separating a light 

 siiperciliaiy stripe from the light color of the checks. The lining of the wing and the axillars are pure 

 white, the latter with a segregation of dusky spots near the earpo-nietacarpal joint.
