40 A FIRST TENTATIVE LIST OF THE BIRDS OF THE 



margined with white ; a very broad conspicuous white wing bar 

 on the lower surface of the quills, not extending to the first three 

 primaries, occupying the bases of the secondaries and later 

 primaries, and running some distance down the webs of the 

 fourth and fifth primaries, the two last to which it extends. 



Upper surface a dusky brownish ashy, with a faint olivace- 

 ous shade (I guess this specimen was a female, I dare say the male 

 is more cyaneous;) tail and upper tail-coverts plain hair 

 brown ; the outermost feather on each side, with a sullied 

 white wedge-shaped spot on the inner web at the tip, and a 

 corresponding speck on the next feather. 



Wings dark hair brown ; the whole of the median coverts 

 pure white ; the third and succeeding primaries with dull grey 

 edgings to the outer webs above the emarginations, and the 

 secondaries with an olivaceous shade on the outer webs. 



The lower tail-coverts have a pale dingy rufous tinge. I 

 do not know whether this is dirt or natural. The flanks are 

 marked with spots similar to those of the upper abdomen, but 

 smaller and duller coloured. 



It is satisfactory thus to recover a bird hitherto unseen by 

 any European, and generally confounded with G. interpres, 

 just as it was to find out in my Rallina telmatopJiila (S. F., 

 VII, 142 and 451) the real Rallus superciliaris, Eyton, so 

 long and so inexplicably confounded with Porzana cinerea. 



Another scarcely less interesting species is, I believe, new, 

 and I shall designate it after the gentleman who procured it. 

 Captain "Webber, Chief Adviser of the Rajah of Tonka, in whose 

 territories it was shot. 



Ixidia webberi, Sp. Nov. ? 



ZiJce I. squamata, iut the yellow of upper surface darTcer and more oliva- 

 eelous ; the abdomen and fianlcs like the breast, and almost the whole inner web 

 (^ the outer tail-feather white. 



This interesting species which forms the third of Blyth's 

 genus Ixidifi, distinguished amongst other things from Brachy- 

 podius, by its square tail and shorter and less full upper tail- 

 coverts, runs very close to Ixidia (Ixos) squamata, Tem. P. 

 C, 453, fig. 2 ; but yet differs sufficiently to be instantly separ- 

 able therefrom. 



The following are dimensions from the dry skin : — 

 Length, 6*0; wing, 3'2 ; tail, 2*75; tarsus, 0*6 ; bill, at 

 front, from frontal bone, 0'62.
