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

 In Pants afrirapifhts 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 Pants meridional** is slightly longer. 



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

 also from Mexico. 



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

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

 mature bird of C. ultramarina (Temm.). 



I have compared specimens of Passerculus zonarius, Bp. (sp. 187) 

 with examples of Penccea 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 Coturniculus hensfowii (sp. 187), upon further 

 comparison does not seem distinct from the ordinary C. passerinus, 

 of which I also possess specimens from Guatimala. 



2. On Three New Species of the genus Todirostrum. 

 By Phieip Lutley Sclater, M.A., F.L.S., etc. 



(Aves, PI. CXXV.) 



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 Villavicc ncio, a Naturalist who was some time resident at Porto 

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

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

 certainly undoscribed. 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. rufilutum.

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. uigrieeps, mihi (P. Z. S. 1855, 

 p. 70. pi. 84. fig. 1), from which it may be at once distinguished by 

 the fine deep chestnut colouring of the bend of the wing. It is, I 

 think, the most beautiful species of this group yet discovered.
