178 ZOOLOGY. 



the parents, but want the gray on the head and neck, those parts being greenish above and 

 pale yellow below. I believe the gray of the head and neck soon wears off in the adult, as 

 they look faded and greenish after June. I have since found it common in August as far east 

 as Fort Laramie, Nebraska Territory. C. 



This bird is very abundant between the Cascade mountains and the Pacific coast. In habit 

 it resembles others of the group, and is generally found among bushes and thickets. Dr. 

 Townsend, who first described the species, named it in honor of William Frazer Tolmie, M. D., 

 at that time surgeon to the honorable Hudson Bay Company, and now a chief factor in the 

 same corporation. During my residence in Washington Territory, as a neighbor to Dr. Town- 

 send, I was frequently under obligations to him for curious and rare specimens in different 

 branches of natural history, for many professional favors, and for oft repeated kind hospitality, 

 which was all the more agreeable because seasoned with the discourse of the highly educated 

 intelligent gentleman mine host. 



A specimen obtained by me at Fort Steilacoom had the bill dusky above, paler below; legs 

 pale flesh color inclined to dusky. In these characters they differ slightly from those recorded 

 in the specific character given above, which are from specimens obtained by Dr. Cooper. 



These, as well as the other ground warblers, seem to be entirely insectivorous, all the stomachs 

 which I have examined containing fragments of coleoptera and other insects. 



They are not a very shy species, but as they frequent thick brush and heavily leaved 

 thickets, behind the foliage of which they are so throroughly secreted, it is frequently difficult 

 to obtain them. S.

The orange-crowned warbler is very abundant in the vicinity of Fort Steilacoom. One also 

 obtained at Fort Dalles, 0. T. 



Habits much like those of the ground warbler. They keep in shady places among thick 

 brush, generally near water courses. S.
