1869.] MESSRS. SCLATER AND SALVIN ON MEXICAN BIRDS. 363 
was really of this species. Salvin has received a skin of this Cyano- 
citta from the vicinity of Oaxaca, collected by Mr. A. Fenochio. 
9. PstLoRHINUS MORIO (Wagler). 
Two skins of this bird, marked ¢ et 92, and coloured alike, ob- 
tained from the tierra caliente of the Atlantic, where Mr. le Strange 
says they are ‘‘ very common, and often follow the passer-by, taking 
short flights from tree to tree, and making a harsh and discordant 
noise.”’ 
This bird has long been confounded with the Psilorhinus meai- 
canus of Rippell, which is immediately distinguishable by its white 
belly and the broad white terminations of the rectrices. Riippell 
gives the locality of his species as Tamaulipas ; but all the Mexican 
specimens of Psilorhinus which have come under our notice have 
belonged to the black-tailed Ps. morio, while all the Guatemalan and 
more southern examples have been of the (so-called) Ps. mexicanus. 
Under these circumstances it is not unlikely that there may have 
been some mistake in Riippell’s locality. 
The two species (if such they be) will stand as follows :—

10. Srrrasomus OLIvAcEus (Max.). 
We have already given our reasons for using this name for the 
bird usually called S. sylvioides (cf. P. Z. S. 1868, p. 630). 
11. CoaTura RvTILA (Vieill.), Sclater, Cat. A. B. p. 283. 
Mr. le Strange’s collection contains a pair of this beautiful Swift 
from the tierra fria, the first Mexican specimens we have seen of 
it. Mr. Lawrence has lately presented to Sclater an Ecuadorian 
skin of the bird, which agrees perfectly with Mexican and Gua- 
temalan examples.
