viridi marginatis: cauda nigra, rectricibus intermediis extus 
cerulescenti-viridi late marginatis : regione parotica nigra:

Hab. Costa Rica. 
Obs. Species Calliste schranki maxime affinis, sed fronte nigra 
et pectore flavo omnino caret, et rostrum magis tenue habet. 
A collection of Costa-Rican birds recently received from Mr. 
Julian Carmiol contains a single skin of this new Calliste. It is 
marked “female ;”’ but the male is probably hardly different, though 
it may be a little brighter in colouring. 
The only described species at all resembling it is Calliste schranki, 
which is of the same general appearance, but may readily be distin- 
guished by the characters given above. 
In his last catalogue of Costa-Rican Birds*, Mr. Lawrence in- 
cluded five Tanagers of this group—namely, Calliste icterocephala, 
guttata, gyroloides, francesca, and dowii. Salvin has received 
examples of all these from the same district. The present bird is 
therefore the sixth Costa-Rican species of Calliste. 
2. SYNALLAXIS AREQUIP#. 
Synallavis orbignii, Sel. et Salv. P. Z. 8. 1867, p- 986, nec auctt. 
Supra fusca, pileo parum obscuriore, uropygio rufo: alis extus 
Susco-nigris, tectricibus et secundariis fusco indistincte margi- 
natis: cauda nigra, rectrice una utringue extima fere omnino et 
duabus utrinque proximis in pogonio exteriore rufis: subtus 
lacteo-alba, macula gulari, tectricibus subalaribus, hypochon- 
driis et crisso rufis : rostro obscure corneo, pedibus nigris : long. 
tota 6°8, ale 2°7, caude 3:0, tarsi 1:0. 
Hab. in vicin. urbis Arequipz, Peruy. occidentalis. 
We now find that we have been wrong in identifying this bird 
with S. vrbignii (S. humicola, d’ Orb.) —that species being easily 
distinguishable on comparison by its rufous wings, and the more 
rufescent tinge of the upper plumage, particularly on the head and 
forehead. In S. orbignit the rufous colour of the secondaries extends 
through both webs, and makes a conspicuous large square basal patch 
of this colour. This patch is quite absent in the present bird. 
For an opportunity of examining the true S. orbignii, and thus 
correcting our error, we are indebted to Mr. T. Moore, Curator of 
the Derby Museum, Liverpool, who has kindly submitted to our 
inspection two skins of it belonging to that collection. They were 
obtained by Mr. Bridges, in Bolivia, and purchased by the late Lord 
Derby through Mr. Cuming in 1846.
