352 BIRDS OF THE REPUBLIC OF PANAMA PART 2 



three found in Costa Rica and Nicaragua are here outlined briefly. 

 The two of Panama that follow will be given in more detail. All are 

 listed under castaneoventris, as the oldest of the species names 

 available. 



Lampornis castaneoventris pectoralis Salvin, Ann. Mag. Nat. Hist., 

 ser. 6, vol. 7, no. 4, April, 1891, p. 377. (Northwestern Costa Rica.) 



Characters. — Male with throat deeper purple than in any of the 

 other dark-throated populations ; otherwise nearest in color to Lampor- 

 nis c. homogencs, but breast with the green restricted, the lower area 

 darker, near hair brown, under tail coverts darker, and green of fore- 

 neck and upper tail coverts decidedly darker. 



Female, like L. c. calolaema, but crown darker ; averaging faintly 

 paler below, especially on the breast. 



Measurements. — Males (3 from Nicaragua and Costa Rica), wing 

 59.3, 59.3 (third specimen molting), tail 32.9-33.7 (33.2) , oilmen from 

 base 20.5-21.4 (20.8) mm. 



Females (4 from Nicaragua), wing 54.0-55.0 (54.4), tail 29.4-31.9 

 (31.2), oilmen from base 20.6-21.7 (21.1) mm. 



Mountains of northwestern Costa Rica and Nicaragua. 



From the few specimens examined this appears to be a valid form, 

 though information as to its distribution as yet is limited. Salvin in the 

 original description said merely "Adult male. Similar to that of 

 O. calolaema in all respects except that the breast, when viewed from 

 in front is nearly black, and not glittering green. The female is 

 probably indistinguishable from that of O. calolaema. Hab. Costa 

 Rica." Warren (Type-Spec. Birds Brit. Mus., vol. 1, 1966, p. 222) 

 says of the type "Costa Rica, 1883. Obtained by H. Whitely ; prepared 

 by Endres." The date cited must be that on which the specimen was 

 purchased for the British Museum from the dealer Henry Whitely, 

 who had an agency for natural history material in Wellington Street, 

 Woolwich. E. R. Endres, a correspondent of Spencer F. Baird, sent 

 three lots of specimens, mainly hummingbirds, to the Smithsonian 

 in 1867, 1868, and 1869. These were flat skins, with no data except 

 the name of the country. A number were sent out in exchange, so that 

 apparently it is one of them that served as Salvin's type. A letter in 

 the Museum accession files relating to the final shipment in 1869 has 

 Endres' signature (accented as shown here) but no information as to 

 where the birds were collected. Males from western Nicaragua agree 

 with an Endres specimen in the U. S. National Museum dated 1867 

 with the locality Costa Rica. It is assumed that the type locality is 

 in the northwestern mountains near Nicaragua. Lawrence (Ann.
