individual and sexual differences and perhaps also to dif- 

 ferences in age, thns a very great material from many parts 

 of the range must be carefully examined before the question 

 can be solved. Until tbat bas been done, T think it better 

 to refer tbe birds from Nicaragua and Costa Rica to G. 1. 

 larvata, witb an indication, as already remarked by Carriker, 

 tbat C. 1. larvata doubtless intergrades into C. 1. fanny in 

 the southern parts of its range.

As northernmost range for the occurrencc of the Tawny- 

 crested Tanager was hitherto stated Costa Rica, w^here it is 

 said by Carriker (1. c, p. 845) to be confined to the Ca- 

 ribbean foot-hills and the higher parts of the lowlands from 

 about 500 to 2,000 feet, being on the whole a very rare bird. 



The present Nicaraguan specimen is rather a great one, 

 slightly exceeding the greatest measurements recorded by 

 Ridgway (op. cit. II, 1902, p. 136), in having wing 78, tall
