Uutte, Glassy, and Suaggy Lakes, but the more isolated ones are prob- 

 ably kuownouly to liuuters, being far removed from settled localities, and 

 many of them are nameless. It is probable that all of those lakes which 

 contain fish are regularly resorted to by Loons as breeding jdaces. On 

 July 10 I waded out to a narrow sand bar in Butte Lake, upon which 

 a Loon had been sitting, and found her nest or rather egg, for although 

 two eggs is the regular number for this species there was but one in 

 this instance, which was lying on the bare sand. It measured 3.40 by 

 2.18. Our eflbrts to shoot Loons here proved quite unavailing, for they 

 were far out of shotgun range; and after much ammunition had been 

 expended in vain by other and better marksmen than 1, we decided 

 that they could certainly dodge a ride ball at two hundred yards dis- 

 tance, let the aim be directed at them or in front of them, or where we 

 would. At short range these birds can be killed with the shotgun by 

 aiming at the water before them where they receive the charge in 

 Ijluuging forward to dive. Loons were observed nowhere else than on 

 these lakes, with exception of one specimen seen in the possession of an 

 Indian at the month of Pitt River. 



Urinator pacificus (Ijawr. ). I'acific Loon. 



Occurs'irregularly at Humboldt Bay, where Mr. Charles Fiebig ob- 

 tained the specimens contained in his collection at Eureka. 



Urinator lunime (Guiin). licd-iJiroalcd Loon. 



The only instance of the appearance of the lied-throated Loon in this 

 region is that of a specimen obtained at Fort Crook by Captain Feilner. 



Family STERCORAEIID^E. Skuas and Jaegers. 



Stercorarius parasiticus (Linn.), rurasiiiv Jaeger 



I saw a specimen of this bird in the collection of Mr. Fiebig, at 

 Eureka, who shot it on Humboldt Bay, and who says it is not often seen 

 there. 



Family LARID^E. Gulls axd Tkkns. 



Larus glaucescens Naum. (llancous-winijvd Gull. 



This and the next species were both obtained at Humboldt Bay in 

 December, glaueescens, however, being quite rare com])ared with the 

 great numbers of occidentalis gathered there. 



Larus occidentalis Aud. IVi'^ta-n Gull. 



Icarus californicus Lawr. California Gall. 



The California Gull was found in abundance at Eagle Lake late in 

 June, but there were comparatively few breeding there, the only suit- 

 able localities, two small islands, being apparently monopolized by cor- 

 morants Phalacrooorax dilophus alboclllatus and pelicans. It was nu- 

 merous at Humboldt Bay in December. I obtained a single indi-
