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. lah-adorides. I have 

 acquired a second specimen of this species, since my original 

 description vsras published, from M. Verreaux 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 50, alse 2'8, caudse 1*9, poll, et dec. Angl, 

 Hab. 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

 the naturalist attached to Lieut. Michler's surveying-party on the 

 Isthmus of Darien. 



3. Calliste FRANTZii. Callispisa {Chrysothraupis) frantzii, 

 Cab. Journ. f. Orn. 1861, p. 87, from Costa Rica, a species nearly 

 allied to Calliste icterocephala, discovered by v. Frantzius, 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 ' 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-
