still the use of the letter T, instead of P, is unaccounted for. 

 If T is a misprint for P, why rufa ? And yet Sir Stamford 

 could not have meant T as the initial of " Tiga ;" for that word, 

 in a generic sense, was not used until sixteen years later by 

 Kaup. The question, however, is of small importance ; for the 

 oldest title for the Javan species appears to be Picus javanensis, 

 Ljungh (Act. Stockh. xviii. p. ISi, 1797), unless, indeed, the 

 Sumatran and Malaccan Tiga differs from the Javan. 



22. Hemilophus JAVENSis (Horsf.). 



Swainson's generic name cannot be used having been previ- 

 ously employed (Audinet-Serville, Entom. 1835). Mulleripicus, 

 Bp., next in priority, can only be adopted for P. javcnsis and its 

 aflfines on the assumption that they are congeneric with P. 

 pulverulent us, Temm."^, the type of Bonaparte^s genus. Dr. 

 Cabauis has separated them under the title of Thriponax. 



The Burmese species M.feddeni, Blanfordf { = Picus crowfurdi, 

 J. E. Gray?), is easily to be distinguished from T. hudgsoni (Jerd.) 

 by having a very broad white mark on the inner webs of the whole 

 of the quills, primary and secondary, the short first primary in- 

 cluded. This white mark occupies about half the length of each 

 quill. In T. hodysoni, the white marking is restricted to the inner 

 webs of the primaries at their insertion, and is only to be de- 

 tected by pushing aside the under carpal coverts. On the inner 

 webs of the secondaries it is more developed, but is not discern- 

 ible without first removing the white under wing-coverts. The 

 dimensions of the wings and tail of the two species are about 

 equal, but those of the bill of T. hudgsoni are much greater. 

 The extent of white on the back of T. feddeni is also more con- 

 siderable. In full-plumaged males of T. feddeni, a conspicuous 

 pure white oval spot occupies the tips of the 3rd, 4th, 5th and 

 6t'h primaries. In younger males these spots are dirty brown, 



* Both Mallierbe and Dr. Cabanis have superseded Temminck's title by 

 that oi gtitturalis, Valenc, ex Sumatra. The 66th livraison of the ' Recueil' 

 was published 10th June 1826. The 40th volume of the Diet, des Sc. Nat. 

 was likewise published in 1826; but the month has yet to be determined. 

 Until that is decided, it seems best to retain the title under which the 

 species was first figured, and by which it is best known.
