6*. guttatus. After comparison we were positively informed that there 

 is no difference between the birds from the two localities. 



Thus far this species has been taken in Costa Rica only on the Volcan 

 de Miravalles, at an altitude of about 2,000 feet, where it was first discov- 

 ered by Mr. C. F. Underwood in 1895. It resorts exclusively to the lichen- 

 covered stone-heaps found scattered in abundance over the pastures on 

 the volcano. In habits it is very similar to the common Rock Wren 

 of the Western United States (Salpinctes obsoletus) and it very probably 

 builds its nest in the crevices between the rocks in the same manner as 

 the North American bird.

(Carriker). Five specimens. 



This is one of the rarest of the genus in Costa Rica and has a rather 

 local distribution, being found only in the Caribbean lowlands, from sea- 

 level up to about 1,000 feet. I first found the bird along the Sicsola River, 

 where they frequented the wild-cane brakes and a high tangled grass found 

 only along the river banks, known as "Gamilote." I never saw it in the 

 forest. I found it also in the vicinity of Guapiles, where two birds were 

 secured in the brush growing alongside the railroad-track. It habits are 

 very similar to those of the following species, to which it is evidently 

 closely related.
