ACTODROMAS BAIRDI Coues 



(1>8.) Uaird's Sand Pipkr. 



Ah)iiy the Arctic coast, from Point Hoj)e to Point Barrow, during the summer of ISSl, wlierever 

 we lauded from the Corwin this si)ecies was found common, especially at Point Barrow, where 

 forty or fifty were observed scattered about the edges of the pools and sand-s]>its at that place 

 during our visit. It occurs spai'ingly on tiie 8il)erian shore, an<l a young bird has been sent to 

 the Smithsonian Institution whicii was obtained on Arakamachechi Island, near Saint Lawrence 

 Bay. On the coast of Norton Sound it is a rare liird, occurring only occasionally during the 

 migrations and rarely if ever breeding in that vicinity, it is not recorded from any of the Bering 

 Sea islands, although it is undoubtedly found on Saiid Ijawrence during the nesting season and 

 visits the others as a stray migrant. 



ACTODROMAS MIN0TILLA (Vieill. i Bp. 



(99.) The Least Sand Pipeu. 



Like the preceding, this Sand Pi2)er is very rare on the Norton Souiul shore of Bering Sea, 

 and thence north along the Arctic coast. It is considerably outnumbered by the last species. 

 There is no record of its occurrence on the Siberian shore, nor is it known from any of the Bering 

 Sea islands. 



PELIDNA ALPINA AMERICANA Cass 



(100.) The Red Backed Sand Piper. 



About the entire Bering Sea shore of Alaska, north of Kotzebne Sound, and across along the 

 adjoining coast of Siberia, wherever we landed during the summer of 1881, this bird was found 

 abundant. A number of specimens were secured at Cape Wankarem, on August 7, 18S1, and are 

 identical with specimens secured on the American coast. It breeds wherever found iu this region, 

 and is one of the commonest waders, arriving at Saint Michael's early in ISlny, and it appears 

 throughout this regiou as rapidly as the snow leaves the ground sufficiently bare for birds to 

 secure their food. It was also noted as common on Saint Lawrence Island, in Bering Sea, but it 

 is unknown elsewhere on the islands of tins sea, except as an occasional visitant to the Seal 

 Islands during the migrations. 



EREUNETES PUSILLUS iLinn.) Cass. 



(101.) The Semi-palmated Sand Piper. 



Alohg the entire Alaskan coast, from the Peninsula of Aliaska to Point Barrow, as well as 

 on the coast of Northeastern Asia and Saint Lawrence Island, Bering Sea, this small Sand Piper 

 is a common summer resident, breeding wherever the land bordering the coast is level and dotted 

 with pools or lakelets. It is perhajis the most iibuudant of the waders throughout this I'cgion, 

 and its rai)id trilling note is heard on every hainl during the day in the mating season. 



CALIDRIS ARENARIA (Linn.) lUig. 



(102.) The Sanderling. 



In Mr. Ball's list of the birds of Alaska he gives the present species as common at Nulato 

 and thence down the Yukon to the sea-coast. During the time of my residence in the territory, 

 and incbnling the various jioints visited during the cruise of the Corwin, on both the Siberian and 

 American shores, not a single individual of this lird was seen. It occurs, however, in this 

 I'egion, but is irregular, and I am inclined to think somewhat rare. We learn from a letter in the 

 New York Herald, from Mr. Newcomb, that while the Jeannette party were passing to the mouth
