from Sumatra, Java, and Borneo, but is not known in China. 

 Mr. Pryer remarks that the insect fauna of the Loo-choo 

 Islands is " almost entirely Malayan,^" so that we need 

 scarcely try to account for the existence of this Duck by 

 suggesting that it may have been introduced. 



Now that the Loo-choo Islands have been proved to possess 

 so many points of ornithological interest, it is to be hoped 

 that they will be speedily explored. Dr. Guillemard, in his 

 cruise of the ' Marchesa,^ has drawn attention to the extreme 

 good nature of the inhabitants, but he was not very suc- 

 cessful in his ornithological researches on the islands. In 

 the 'Proceedings of the Academy of Philadelphia,^ 1862, 

 p. 312, there is a list of twelve species of birds collected on 

 the Loo-choo Islands in 1854 by the exploring expedition 

 under Capt. Rodgers. Six of these have been obtained by 

 Mr. Pryer. Four others are evidently migrants, namely : — 



41. Ardea alba. 



42. numenius arquatus, 



43. totanus hypoleucus. 



44. fuligula marila. 



Of the two remaining species obtained by Capt. Rogers, 



45. Ardea grayi 



may possibly be a resident, and 



46. CoLUMBA intermedia 



a more or less domesticated Pigeon, introduced in prehistoric 

 times.
