 Lion Hill (M'Leannan ^). — Colombia ^ ^ ; Ecuador '^ ^. 



This species was first described by Mr. Sclater from a specimen obtained by M. 

 Boucard at Suchapam in the Mexican State of Oaxaca ^, and it has since been traced to 

 Guatemala and to the State of Panama, Colombia, and "Western Ecuador, for birds 

 from the latter country do not differ in any essential particular from the Mexican 

 type. IVo female or young birds obtained by Mr. Nutting in Nicaragua agree fairly 

 with a female from Western Ecuador, one of the types of 0. mthiops, but which has 

 since been united to 0. funereus ^. The bill in these birds is larger than in any male 

 of 0. funereus in our possession ; but, knowing how variable the bill is in 0. torridus, 

 we do not attach much importance to this difference. Mr. Eidgway thinks the Nica- 

 ragua birds hardly likely to belong to 0. cethiops ; but if, as we maintain, 0. mthiops is 

 the same as 0. funereus, the probability of there being another species inserted in the 

 middle of the range of that bird is very unlikely, and the fact can only be established 

 after an examination of more specimens than are at present available. 



Our Guatemala birds were all obtained in the low-lying forest-country north of 

 Cohan in Vera Paz, where, however, the bird was not common. Mr, Nutting shot his 

 examples in a patch of plantains and in some high marsh-grass, their habits being 

 similar to those of Guiraca concreta. 



AMAUROSPIZA.

This peculiar form has a general resemblance to Guiraca, especially to the small 

 G. parellina, but on closer examination the shape of the bill will show that there is no 

 near relationship. 



The type A. concolor, so far as we yet know, is restricted to Costa Eica and the State 

 of Panama; but the bird is so rare that little can be said about it. 



The bill is broad at the base, the culmen rather sharp and gradually curved from
