At the time when Mr. Ridgway separated southern specimens of P. 

 ochraceiceps from the northern, under the name of pallidipectus, but very 

 little material was available for comparison; but since that time large 

 series of southern birds have been brought together, and they prove that 

 the differences pointed out by Mr. Ridgway as diagnostic of his pallidi- 

 pectus were only of an individual character, and that the birds from Mexico 

 to Panama are practically alike, at least not sufficiently distinct to be 

 worthy of subspecific separation. 



The range of Pachysylvia ochraceiceps in Costa Rica covers the whole of 

 the Pacific lowlands and foot-hills up to about 2,000 feet or a little lower, 

 while on the Caribbean side it is found in the lower foot-hills, from about 

 800 feet upward to about 2,000 feet. It is found only in the heavy forest, 

 and is usually to be seen going about in small bands, in company w r ith 

 several other species, usually some of the small arboreal Formicariidce, 

 etc. It is a common bird in the Terraba Valley, but I find no record of 

 its presence in Talamanca.
