362 MESSRS. SCLATER AND SALVIN ON MEXICAN BIRDS. [May 27, 
species (called by Baird P. mesoleucus) is the true P. fuscus of 
Swainson, and that the Californian bird (called P. fuscus by Baird 
and others) should be termed P. crissalis. Sclater’s collection con- 
tains an original specimen of P. mesoleucus, collected by Kennicott 
in New Mexico, which agrees perfectly with the skins in Mr. le 
Strange’s collection, and with others obtained in Mexico by Boucard 
and De Saussure. Mr. le Strange notes that this bird is ‘ common 
in the valley of Mexico.” 
4. Carpopacus cassinu, Baird, B. N. A. p. 414. 
Three specimens (2 ¢ and 1 Q) of this species, obtained by 
Mr. le Strange, are the first of it we have seen. As stated by 
Baird, it is most like C. purpureus, but remarkable for the large 
size and elongation of the bill. Baird’s specimens were from New 
Mexico.

P. Z. 8. 1864, p. 174. 
Three skins of what we believe to be this North-American species, 
agreeing with one in Sclater’s collection from the same locality. We 
much doubt the distinctness of C. macroptera, Du Bus (Esq. Orn. 
t. 23), which appears to be the same bird. 
6. Icrerus BULLOCKU, Sw. Ph. Mag. 1827, i. p. 436; Baird, 
B.N. A. p. 549. 
Examples of both sexes of this species, which is stated to inhabit 
the tierra fria, and is called “ Calandria nogalera.” 
7. IcTERUS ABEILL&I (Less.); Sclater, P. Z. S. 1860, p. 252, et 
1864, p. 175; Cat. A. B. p. 130. 
A pair of this species, stated to have been brought in alive and 
kept in a cage for some time. Mexican name “ Calandria mielera.” 
The female does not appear distinguishable from that of I. bullockit ; 
the males are readily separable by the black sides and uropygium of 
the present species. 
8. CYANOCITTA CALIFORNICA (Vig.); Sclater, Cat. A. B. p. 143. 
Aphelocoma floridana, Bp. C. R. xhii. p. 956. 
Cyanocitta floridana, Scl. P. Z. 8. 1856, p. 300. 
Mr. le Strange’s skin (obtained in the tierra fria) agrees well with 
a Californian specimen in Sclater’s collection, and with the charac- 
ters whereby Baird distinguishes C. californica from C. woodhousit. 
It is white without any bluish tinge below, and the crissum is 
nearly pure white. It is probable, therefore, that Prof. Baird has 
wrongly referred his specimen no. 8465, from Mexico, to C. wood- 
housit. 
We have little doubt that Sallé’s specimen (no. 186 of his first 
collection), referred by Sclater (following Bonaparte) to C. foridana,
