General Meeting, Nov. 2, 1887. 

 The President, Prof. F. W. Putnam, in the chair. 



After calling the meeting to order the President welcomed the 

 members to the Society's hall once more, and hoped that the pa- 

 pers announced for the evening foreshadowed an interesting season. 



The President then spoke in fitting terms of the deaths, dur- 

 ing the summer, of Ex- Vice President, Mr. R. C. Greenleaf and of 

 Prof. 8. F. Baird, an Honorary Member of the Society, and stated 

 that notices of both members would be given at a future time.

NOTES ON SOME TYPE-SPECIMENS OF AMERICAN 



TROGLODYTID^E IN THE LAFRESNAYE 



COLLECTION. 



BY ROBERT RIDGWAY. 



Curator Department of Birds, U. S. National Museum. 



Having been kindly permitted by the authorities of the Boston 

 Society of Natural History to examine the type-specimens of a 

 number of Lafresnaye's species belonging to the genera Campy- 

 lorhynchus Spix, Thryophilus Baird, Thryothorus Vieill., and 

 Troglodytes Vieill., — species for the most part involved in more 

 or less uncertainty, — it affords me much pleasure to present here- 

 with the results reached by the examination in question. 



1. Campylorhynchus brunneicapillus, Rev. Zool., 1846, 94. 

 (Picolaptes brunneicapillus, Mag. de Zool., 1833, Ois. pi. 47.) 

 Type, No. 2600, "California." 



This specimen agrees exactly with examples from the south- 

 western border of the United States (Texas to San Diego, Cali- 

 fornia) identified as C. brunneicapillus by Professor Baird and 

 other American writers, and is therefore not C. affinis Xantus, as 

 suggested by Mr. Sharpe (cf. Cat. B. Brit. Mus. vi, p. 196). 



2. Campylorhynchus unicolor (Rev. Zool., 1846, 93). Type, 

 No. 2598, Guarayas, S. W. Brazil. 



3. Campylorhynchus unicoloroides (Rev. Zool., 1846, 316). 

 Type, No. 2599, Bolivia. 



The former of these two specimens is in decidedly abraded plum-
