really distinct, although closely allied species. In its upper plumage 

 Parns meridionalis differs from P. atricapillus in having the back 

 deeper cinereous without any tinge of brown — the narrow outer 

 edgings of the secondaries are brownish and not white, and the black 

 does not extend so far down the nape. Below, the plumage is also 

 much darker ; the whole abdomen and crissum being of a nearly uni- 

 form rather mouse-coloured cinereous, with a pale whitish medial line. 

 In Parus atricapillus the whole middle of the belly is much lighter 

 and more white, and the sides are deeply tinged with pale rufous. 



There is not much difference in the size of the two species, but the 

 tail of Parus meridionalis is slightly longer. 



Mr. Gould's collection contains an example oi Parus meridionalis 

 also from Mexico. 



With regard to other species contained in the same catalogue, I 

 have to state that Cyanocitta jioridana (sp. 135) is probably an im- 

 mature bird of C ultramarina (Temm.). 



I have compared specimens oi Passer cuius zonarius, Bp. (sp. 187) 

 with examples of Peuccea Lincolni, which I obtained in the United 

 States, and can discover no difference between them, and I consider 

 these two names to be synonymous. 



The bird named Cotiamiculus Henslowii (sp. 187), upon further 

 comparison, does not seem to be distinct from the ordinary C. pas- 

 eerinusj of which I also possess specimens from Guatemala, 



On Three New Species of the genus Todirostrum. 

 By Philip Ltjtley Sclater, M.A., F.L.S., etc. 



Sir William Jardine has kindly lent me some specimens of birds 

 of the genus Todirostrum out of a collection received by him a short 

 time ago through Professor Jameson of Quito from the Rio Napo. 

 They were obtained in that locality, as I have reason to believe, by 

 Don Villavicencio, a Naturalist who was for some time resident at Porto 

 del Napo, on the Upper Rio Napo, where the Italian traveller Oscu- 

 lati mentions having seen him in 1847. Two of them appear to be 

 certainly undescribed. The third is not in a very good state of pre- 

 servation, but I think it may possibly be referable to Dr. Hartlaub's 

 T. rufilatum.

This is a typical Todirostrum, but with the beak rather shorter 

 and broader than in T. cinereum. The only known species which it 

 at all resembles in colouring is T, nigriceps, mihi (P. Z. S. 18.55,
