350 BIRDS OF THE REPUBLIC OF PANAMA — PART 2 



wing 62.6-66.1 (64.4), tail 35.2-37.7 (36.7), oilmen from base 19.0- 

 21.1 (20.1) mm. 



Females (7 from Costa Rica, 1 from "Panama"), wing 57.4-60.4 

 (58.3), tail 31.0-34.3 (32.6), culmen from base 20.6-22.3 (21.4) mm. 



Status uncertain. Recorded from Chiriqui. 



Inclusion of this species from western Panama began with the 

 statement by Hartert (Journ. f. On., 1900, p. 366), that "Coeligena 

 hemileuca ist dem Tring-Museum neuerdings aus Chiriqui (Panama) 

 zugegangen." In the Rothschild collection in the American Museum of 

 Natural History, there are 2 skins, a male and a female, purchased 

 from the dealer Rosenberg (that from their appearance were pre- 

 pared by Arce), labeled Chiriqui without other data. The white-bellied 

 mountain gem according to Slud (Bull. Amer. Mus. Nat. Hist., vol. 

 128, 1964, p. 159) is found in Costa Rica on the Caribbean slope in 

 the Subtropical Zone of the central mountain area. Slud believed 

 "that almost certainly it continues onward to Panama." Its status as 

 a bird of the Republic, however, is at present uncertain. Search for 

 it should be made in the high mountains of western Bocas del Toro. 



It may be noted that Salvin named this species from specimens 

 collected in Costa Rica by Arce in 1864, as indicated by the introduc- 

 tory paragraphs (loc. cit., p. 579) of the original description, and 

 verified by skins that I have examined from the Salvin collection in the 

 British Museum. It seems possible that the 2 attributed to "Chiriqui" 

 which have no other data may have been taken at the same time in 

 Costa Rica. 



In the original description Salvin listed his material as "Hab. Costa 

 Rica (Turrialba, Tucurrique.)" When he compiled the section on 

 hummingbirds for the British Museum catalog (Salvin, Cat. Birds 

 Brit. Mus., vol. 16, 1892, p. 311) under this species he listed 2 males 

 and 2 females from Turrialba, and 1 male from Tucurrique. Rachel 

 Warren (Type-Spec. Birds Brit. Mus., vol. 1, 1966, p. 126) lists 

 "Syntype, Adult male. Reg. no. 1887. 3.22.315. Turrialba, Costa 

 Rica, 1864. Collected by E. Arce. Salvin-Godman collection. There 

 are two other syntypes in the collection." From this it is appropriate 

 to cite the type locality as Turrialba alone. 



LAMPORNIS CASTANEOVENTRIS (Gould): Variable 

 Mountain-gem, Colibri Mudadizo 



Medium size. Green above with white streak behind eye ; two color 

 phases in male, one with purple throat, one with white throat ; female 

 always cinnamon-rufous on lower surface. (The description that 

 follows is based on the two forms found in Panama.)
