BIRDS OF THE GALAPAGOS ARCHIPELAGO— RID(i WA Y. vol. six. 



Messrs. Baur and Adams obtained a Nesomimus on Gardner Island, 

 wliifU lies between Charles and Hood islands, which Dr. Banr thought 

 to be the same as the llood Island form {X. macdonaldi); but as Ciard 

 ner Island lies very close to Charles, it seems more likely to have been 

 N. trifdscidtus. Dr. Baur's specimens having been lost, the question 

 remains to be decided.

Adult male. — (Tyite, 

 No. 110006, r.S.N.M.; 

 Hood Island, Galai)a 

 gos, April 7, 18SS; U. S. S. Albatross.) Above brownish gray, more ashy 

 anteriorly and on lesser wing-coverts, becoming decidedly brown on 

 rump, each feather with a central or mesial sjjace of dusky, these maik 

 ings largest on back and scapulars, nearly obsolete on lower back and 

 hind neck ; wings (except lesser coverts) dull black, the posterior row of 

 lesser coverts, middle coverts, and greater coverts broadly nniigined at 

 tips with white, forming three bands across the Aving; greater coverts 

 and tertials broadly edged with drab or grayish brown, the latter mar- 

 gined terminally with white; primaries and their coverts narrowly 

 edged with pale brownish gra,v or dull whitish; tail blackish dusky, the 

 outer feather with an ill-defined pale brownish-gray space near tip of 

 inner web, next to edge, the second with a mere edging of the same color 

 in corresponding ])osition. A narrow and poorly detined superciliary 

 stripe of white, bordered beneath by a blackish stripe covering lores, 

 extending beneath eye, and tlence along ui)])er edge of auricular 

 region, the rest of the latter dull light gray mixed with black, especially 

 on lower p isterior portion; a broad white nndar stripe, bordered 

 beneath by a narrow interrupted stripe of dusky along each side of 

 throat. Under parts Avhite, tinged with pale drab across chest, where 



1 The specimens collected were lost. Gardner Island being nearer to Charles than 

 to Hood, the species may Lave been X. trifasciatus.
