The typical specimen was described by the late Prof. Taczanowski from a 

 single specimen, without indication of sex or locality, from the collection of 

 Dr. Raiiuondi, of Lima. It is said to be very similar to Rallu^ aijua/iciit of 

 Europe, and to ditTor from it only in its smaller size, much more rufous colora- 

 tion, and in the absence of the white mark on the throat.
