Glaucidium cobanense was described by Sharpe 1 from an 

 examination of six specimens from Vera Paz, Guatemala, no 

 one of which seems to have been designated as the type. The 

 measurements of the type of G. fisher i and four of the specimens 

 of G. cobanense are given below : — 



Wing. Tail. Tarsus. 



Glaucidium fisheri 



5 Tochimilco, Puebla, Mexico 3.45 2.35 .76 



Glaucidium cobanense 



Ad., Laguna, Vera Paz, Guatemala 



Ad., El Paraiso, Vera Paz, Guatemala 



Juv., Volcan de Fuego, Vera Paz, Guatemala 



On page 199 of the 'Catalogue of the Striges in the British 

 Museum,' are given the following additional measurements for 

 this species: Wing, 3.45; tail, 2.55; taisus, .75. These are 

 evidently taken from a specimen from Cohan, Vera Paz, ob- 

 tained from M. A. Bouvier — one of those referred to in the 

 original description. From these measurements it will be seen 

 that the specimen of G. fisheri, although a female, is only as 

 large as the smallest specimen of G. cobanense and appreciably 

 smaller than the average measurements of five specimens of 

 the latter species. 



The type and only known specimen of this handsome little 

 Owl was shot from a ledge of rocks where it had taken refuge 

 from a passing shower. It was found among the oaks and 

 pines on the southeast slope of Mount Popocatapetl at an 

 altitude of about 6500 feet, near the town of Tochimilco in the 

 state of Puebla.
