A short-tailed species of Synallti.eis, as I should judge from the 

 only specimen under observation, in which, however, the medial rec- 

 triees are absent. It is very nearly allied to Temminck's 8. albescens, 

 but differs sufficiently in its white throat and belly, as far as I can 

 judge from the unique specimen.

I am not certain whether characters of species 32, 33 and 35 have

 energetically at this group of birds, I am unwilling to anticipate him 

 by publishing descriptions of birds which bear his names.

This species is very nearly resembling, but aol perhaps quite iden-
