98 PROCEEDINGS OF THE ACADEMY OF 



(213.) Gambetta melanolecca (Gm.) Bon. 

 Abundant on the Colorado. 



214. Rhyacophilus solitabius (Wils.) Bon. 



A single specimen taken at Fort Whipple, August, 1864 ; at a small pool in. 

 high thick pine woods. 



(215.) Tringoides macularius (L.) Gray. 

 Very numerous along the Colorado. 



216. Numenius longirostris Wilson. 



A single specimen, taken in August, 1864, at Fort Whipple. 



Other limicoline Grallas to be found, probably, are Tryngites rufescens and 

 Limoaa fedoa. 



RALLIDJE. 



(217.) Rallus virginianus L. 



This specie3 has been detected in the Territory. 



(218.) Porzana Carolina (Linn.) 



Colorado River, A. Schott. I think it probable that one or two other Rails 

 are to be added to the avifauna of the Territory. 



(219.) FULICA AMERICANA, Gm. 



Abundant along the Colorado. 



ANATIDJE. 



(220.) Cygnus americanus Sharpless. 

 Colorado River. Fort Mojave, Cooper. 



221. Anser hyperboreds Pall. 

 Common on the Colorado. Specimen taken near Fort Whipple, Oct. 17, 1864. 



(222.) Anser Gambeli, Hartl. 



Anser frontalis, Baird, B. N. A. 1858, p. 762. Young. (Fort Thorn, 



n. ii.) 



Colorado River. Abundant. 



1 am informed by Prof. Baird that he is now satisfied that hi3 A. frontalis is 

 only an immature stage of plumage of A. Gambeli. An analogous plumage is 

 known as one of the conditions of the European Anser albifrons. 



(223.) Bernicla canadensis (L.) Boie. 

 Colorado River. 



(224.) Bernicla Hutchinsii (Rich.) Bon. 



One of the most abundant geese of the Colorado Valley. B. nigricans seems 

 to be exclusively a maritime species. 



225. Dendbocygna fclva (Gm.) Burm. 



A pair, taken in November, about twenty miles from Fort Whipple. This is 

 the only instance in which the species has come under my observation from 

 Arizona. Dendrocygna autumnalis will also doubtless be found in the Terri- 

 tory. 



22(3. Anas boschas L. 



227. Dafila acuta (Linn.) Jenyns. 



228. Nettion carolinensis (Gm.) Baird. 



These three species are abundant on all the waters of the Territory. 



229. Querquedula cyanoptera, (Vieill ) Cass. 



Numbers of this Teal were observed in October on the head of the San Fran- 

 cisco River, near Whipple. At the same season during the following year I 

 saw them in numbers on the Colorado River.
