Flycatcher, f., then philedori) were, as in bad condition, not 

 accepted for the collection. 



We are, however, in possession of another specimen from 

 Eimeo (contained in a different inventory of the year 1806), 

 which was obtained through Herr von Fichtel, and which 

 agrees perfectly with Latham's excellent description of his 

 Long-billed Thrush. It was probably purchased at a dealer's 

 or from a collection in London. Comparing this bird with 

 the other specimens of Tatare in our museum, all from Tahiti, 

 the differences, principally of size, seem to me so considerable 

 that I can scarcely believe in their specific identity. The 

 measurements of the five individuals of T. otaitiensis, Less., 

 in our collection are as follows : —

In all these birds the upperside is more or less variegated 

 by yellowish margins to the feathers, the underside is of a 

 very pale yellowish, the auricular region being of the latter 

 colour, all the rectrices are brown, with whitish tips ; only in 

 no. 4 there are some immature lateral tail-feathers with white 

 tips and yellowish inner webs. 



My friends MM. Finsch and Hartlaub, in their excellent 

 book on the fauna of Central Polynesia, have maintained with 

 cogent arguments the identity of T. longirostris and T. otai- 

 tiensis ; but could they compare the specimens cited above, 

 which agree so remarkably with Latham's description, I believe 

 they would also agree with me that there are two species, as 

 Mr. G. K. Cray formerly (Birds Tropic. Isl.) arranged them' 35 '.
