stating what they are, though you are probably right. You 

 err, however, in saying my specimen of C. farinusa from Panama 

 is C. guatemalce ; it was correctly identified, and I find it agrees 

 with Finsch's description in every particular — head green, edge 

 of wing red, occiput fringed with violet, outer web of outer rectrix 

 marked with blue. 



2. C. GUATEMAL.E, with a light blue crown, I have, from the 

 city of Mexico. 



3. C. DIADEMATA. The specimen from Panama called C. 

 viridigenalis is this species, agreeing with Finsch^s description. 

 I see by my note-book that Cassin's type of C. viridigenalis 

 agrees with C. coccineifrons, as stated by Finsch. 



4. C. AUTUMNALis. I havc this species from the city of 

 Mexico; it is also in Sumichrast's collection from Tehuantepec. 

 Baird tells me the species from Costa llica called C. viridi- 

 genatis is autumnalis; probably he so informed v. Frantzius. 



5. C. FiNSCHi. Specimens are in Sumichrast's collection from 

 S.W. Mexico (now in my hands); also in Grayson's, from 

 Mazatlan, and Xantus's, from Colima. It differs from C. diade- 

 mata in being rather smaller, of a lighter green, the feathers 

 above and below with blackish margins; the front is dull deep 

 crimson (in the other it is bright scarlet), the cheeks are light 

 yellowish-green, the lilac edgings to the feathers of the crown 

 are deeper in colour than those of C. diadeinata. The tail-feathers 

 are without red at the base. You certainly misquote Finsch 

 in saying, " the under surface without dark edgings to the 

 feathers, and the base of the outer rectrix has a red patch." 

 He says just the contrary. 



6. C. LEVAiLLANTi I have from the city of Mexico; speci- 

 mens are in Grayson's collections, made at the Tres Marias, 

 and also in Sumichrast's, from Tehuantepec. One specimen 

 from the Tres Marias seems in unusually perfect plumage : the 

 entire head and neck are yellow as far down as on a line with the 

 bend of the wing — the front, cheeks, and throat pale sulphur- 

 yellow, the remainder deeper in colour; the thighs and edge of 

 the wing are also clear yellow, the flexure scarlet, the outer web 

 of the outer rectrix edged with blue : this and other specimens 

 have the yellow feathers of the neck more or
