284 Lord Tweeddale on Birds from 



between tlic Lieutenant-Governor and these two Frenchmen 

 ledj in about twelve months, to a cessation of their labours 

 and to their departure from Bencoolen ; and Sir Stamford was 

 obliged to undertake the description of the materials col- 

 lected himself, or to allow the results to be published in 

 France. Hence his papers in the "^ Linnean Transactions^"^. 

 The number of species therein catalogued and more or less 

 described is about 168. But some birds obtained in the 

 Prince-of- Wales Island and Singapore are included; and a 

 few species, such as Psittacus ornatus and P. sumatranus, 

 appear to have been introduced into the list through oversight 

 and on the strength of caged birds. 



In 1830 Lady Raffles publishedamemoirf of her late hus- 

 band, to which was appended a catalogue, by Vigors, of the zoo- 

 logical specimens collected in Sumatra under the superinten- 

 dence of Sir S. Raffles, and by Dr. Horsfield of those in Java. 

 About 194 species from Sumatra are enumerated, that locality 

 being stated in each instance; and some species additional to 

 Sir Stamford^s list are discriminated and described as new by 

 Vigors. This catalogue would have been more useful had its 

 author identified all tlie species on which Sir Stamford had 

 previously bestowed new titles, and had the invalid titles been 

 reduced to synonyms — a work, however, subsequently ac- 

 complished in the most thorough manner by Mr. F. Moore % . 



Since 1830 no attempt at a complete account of the birds 

 of Sumatra has been published ; but a good many species not 

 contained in Vigors^s list have been discovered and described, 

 principally by the Dutch zoologists, more particularly by 

 Temminck§ and by Salomon Muller||. Mr. Wallace, during 



* The collection of birds was sent to the E.I. C. Museum in Loudon 

 in 1820, aud of drawiug-s in 1821.
