 original description is listed here from the Proceedings, it seems

AULACORHYNCHUS PRASINUS CAERULEOGULARIS (Gould) 



Aulacorhamphus caeruleogularis Gould, Zool., vol. 11, April 1853, p. 3861. 



("Veragua," restricted here to Boquete, Chiriqui.) 

 Aulacorhynchus caeruleogularis maxillaris Griscom, Amer. Mus. Nov., no. 141, 



October 31, 1924, p. 2. (Guayabo, Costa Rica.) 



Characters. — A mark across the base of the culmen in front of 

 the nostrils varying from broadly black in the center with a suffusion 

 or spot of dull red on either side, to a band of dull red divided in 

 the center by a narrow black line ; somewhat larger ; averaging 

 faintly lighter in color above (but with much variation). 



A male collected on Volcan Baru, Chiriqui, March 10, 1965, had 

 the iris dark brown ; bare skin around eye somewhat bluish slate ; 

 basal half of the line of the culmen broadly black, bordered at the 

 base on either side by a rectangular spot of wine-red that extends 

 back around the nostril ; side of maxilla from base nearly to the tip, 

 and mandible (except as indicated) black; maxilla, except for the 

 marks described at the base of the culmen, yellow ; a narrow vertical 

 line on base of bill yellow on the maxilla, becoming white at the gape, 

 extending thus across the base of the mandible, and as a narrow line 

 along the under margin of each ramus forward to the level of the 

 base of the gonys ; tarsus and toes light dull green ; claws neutral 

 greenish gray. 



Measurements. — Males (10 specimens from Chiriqui), wing 121.1- 

 132.8 (123.8), tail 93.3-115.6 (103.0), culmen from base 59.6-71.2 

 (67.3), tarsus 31.5-36.0 (33.7) mm. 



Females (10 from Chiriqui and Costa Rica), wing 114.0-121.2 

 (117.4), tail 89.5-102.0 (96.0), culmen from base 51.2-62.0 (55.0), 

 tarsus 32.0-34.0 (33.0) mm. 



Resident. Common in forested areas of the Subtropical Zone in 

 the mountains of Chiriqui and Veraguas. (Sight records for Cerro 

 Campana, western Province of Panama). Found regularly in Chiriqui 

 from 1,250 to 1,825 meters, less commonly to 2,375 meters on Volcan 

 Baru. 



On March 19, 1951, I saw 1 fly across a road in heavy forest at 

 900 meters on Cerro Campana. Others have reported them here
