 intention of visiting the great Tambora volcano, and, if possible, of 

 making the ascent. This, however, was found to be beset with so 

 many difficulties as to be impracticable, and the yacht left after a stay 

 of little over a week, having merely touched at two or three places 

 on the north coast of the island. With such very restricted 

 opportunities but little could be done, and I considered myself 

 fortunate in obtaining a small collection comprising examples of 

 some thirty-eight species. 



I am not aware of any account of the Sumbawan avifauna having 

 been published in our own language, and Dr. Jentink informs me 

 that he knows of none from the pen of any Dutch naturalist ; but, 

 from the position of the island, and the researches of Mr. Wallace in 

 Lombok and Flores, few novelties could be expected. The present 

 collection, as far as it goes, bears out this expectation, for, with one 

 or two exceptions, all the species are found on one or both of the 

 last-named islands, and I have but two new species to record. One of 

 these, a Turnix, somewhat resembles T. rujilatus of Wallace, but is
