the one sj^ecimen but slightly more flattened on the other. The 

 white patches on the throat are conspicuous ; the central dark 

 patch on the belly is interrupted with white, and there are whitish 

 specks on the feathers in front of the eyes. The measurements 

 of the two are as follows: — Wing, 149, 157; tail, 67, 71 ; tarsus, 

 41, 43; middle toe and claw, 28, 28; culmen, 15, 15. 



It will be noted that none of the measurements agree in all re- 

 spects with those given by Alathews, but the former bird is most 

 l)robably the s])ecimen examined by him. 



The characters of the mounted specimens are as follows : — 

 Female, the nostrils not very erect, the dark belly marking 

 distinct, the under tail coverts not reaching the end of the tail. 

 The light patch on the upper wing coverts is more noticeable 

 than in any other specimen examined, while there is not a light 

 patch in front of the eye. In the male, there is a light patch in 

 front of the eye, and the facial feathers are lighter than in the 

 female, the nostrils are more erect, and there is a very 

 distinct whitish patch under the throat. The black belly 

 marking is indistinct, and is interru])ted half-way down by the 

 infusion of white feathers. The measurements are : — Female : 

 wing, 162; tail, 70; tarsus, 39; middle toe and claw, 27; culmen, 

 15. Male: wing, 156, tip missing; tail, 71; tarsus, 40; middle 

 toe and claw, 27; culmen, 15. 



The characters of the other specimens before us, which, as 

 stated before, bear Gould's own labels are as follows: — 

 T. leiicoc/aster, Gould.
