Dr. P. L. Sclater on recent Additions to the Genus Calliste. 451 
since elapsed the following additions have been made to the 
list:— 
1. Calliste cyanotis, Sclater, P. Z. S. 1858, p. 294, from 
Eastern Ecuador, a species allied to C. lahradorides. I have 
acquired a second specimen of this species, since my original 
description was published, from M. Yerreaux of Paris, by whom 
it was received in a collection made on the Rio Napo. This 
specimen is more adult than the former, and induces me to 
alter the specific characters as follows :— 
Calliste cyanotis. 
Niger: superciliis latis et elongatis, dorso postico, campterio alari 
et corpore subtus splendide cserulescenti-viridibus; ventre 
medio et crisso cervinis: alarum tectricibus necnon rectricum 
remigumque marginibus angustis cserulescentibus: rostro 
nigro, pedibus fuscis. 
Long, tota 5 0, alse 2'8, caudse 1*9, poll, et dec. Angl. 
Hah. in rep. iEquatoriali (reg. sylvatica orientali). 
2. Calliste LAViNiA,Cassin,Proc. Acad. Sc.Philadelph. 1858, 
p. 178, from the Isthmus of Darien, allied to C. gyrola. I have 
not yet met with this species, which was discovered by Mr. Wood, 
the naturalist attached to Lieut. Michler's surveying-party on the 
Isthmus of Darien. 
3. Calliste frantzii. Callispiza ( Chrysothraupis) frantzii, 
Cab. Journ. f. Orn. 1861, p. 87, from Costa Rica, a species nearly 
allied to Calliste iderocephalay discovered by v. Erantzius, of 
which two similarly coloured examples are in the Berlin Mu¬ 
seum. 
4. Calliste dowii, Salvin, P. Z. S. 1863, p. 168, from Costa 
Rica. (Plate XII.) 
For our knowledge of this fine new species of Calliste we are 
indebted to Capt. J. M. Dow, Commander of the Panama 
Railway Company's steamship c Panama/ whose name is well 
known in connexion with many discoveries in the marine fauna 
of Central America. Capt. Dow procured a single specimen of 
this bird during a visit paid to San Jose, the capital of Costa 
Rica, in the early part of this year, and presented the same 
to Mr. 0. Salvin. Mr. Salvin described the species at the meet-
