buff ; under surface of wings mouse gray, with the under wing coverts 

 tipped and edged lightly with dull white. Bill black ; tarsus and feet 

 dusky neutral gray (from dried skin.) 



Measurements. — Males (6 specimens), wing 92.6-95.3 (93.7), tail 

 46.3-52.3 (49.2), culmen from cere 12. 7-13.9 (13.2), tarsus 27.9- 

 29.1 (28.5) mm. 



Females (3 specimens), wing 92.0-96.1 (94.0), tail 45.7-50.0 

 (48.4), culmen from cere 12. 4-13.4 (12.8), tarsus 27.2-29.4 (28.5) 

 mm. 



Type, male, wing 93.3, tail 52.3, culmen from cere 13.0, tarsus 

 27.9 mm. 



Range. — Western Chiriqui on the southern slopes of the Volcan 

 de Chiriqui near Boquete (El Salto, 1,350 meters elevation), and 

 Frances near El Banco ; and on the coastal plain below Alanje. 

 Apparently restricted in distribution but fairly common when it is 

 found. 



Remarks. — The crested bobwhite of Panama has been known prin- 

 cipally from Veraguas and Code, with few specimens in museum 

 collections from Chiriqui. Present information indicates that the 

 population in Chiriqui is isolated as it is known only from the western 

 part of the province, and there are no records of the related race 

 Colinns cristafus panamensis beyond a point about 10 kilometers 

 west of Sona in western Veraguas. From this western limit the 

 subspecies panamensis is recorded in open country eastward to the 

 western sector of the Province of Panama (where I have found it 

 near Nueva Gorgona, and 10 kilometers east of Bejuco), and south 

 on the eastern side of the Azuero Peninsula through Herrera and 

 Los Santos to Pedasi and near the Rio Oria below Los Asientos ; 

 also in the lower Tonosi valley. It is evident that the additional race 

 here described is one of restricted range, since it is reported to date 

 only from three localities in an area between 50 and 60 kilometers 

 in length. As I have been long familiar with the brown subspecies 

 panamensis of farther east in the Republic the much darker colora- 

 tion of the form here described was immediately evident on my first 

 sight of it in life. It marks the western extension of the species 

 crista til s. 



The new form is named for Mrs. Robert A. Terry, who as Mary E. 

 McLellan Davidson, through her studies in field and laboratory, has 

 added much to our knowledge of the bird life of the Province of 

 Chiriqui.
