Mr. Wilson has handed over to me for examination a considerable number of well- 

 preserved spirit-specimens of Hawaiian birds 1 , requesting me to ascertain their 

 systematic position and to give an account of the more important parts of the 

 structure of the species constituting this almost unique material. All these birds are 

 Oscines, truly aero- and polymyodean. I have not described their skeletons because 

 these are now preserved in the Cambridge Museum, and consequently will be accessible 

 at any future time, should they be considered worth the trouble of describing and 

 figuring. In the following pages I have restricted myself to the description of those 

 parts which are either more perishable than the bones, or which I found to be of 

 greater taxonomic value. In order to investigate the affinities of the birds in question, 

 it was necessary to compare them with many other forms, of which, however, the 

 selection was sadly restricted and determined by the scanty material at my disposal. 



To complete this account, the stuffed specimens of Drepanis pacifica and of Chceto- 

 ptila angustipluma have likewise been examined.
