November 23; Mr. Anthony in the region embraced in his 

 explorations (San Fernando to Ensenada). I saw a few at 

 Comondu in March and April, 1888. 



83. Macrorhamphus scolopaceus (Say). 



Long-billed Dowitcher. — Noted by Mr. Anthony from 

 northwestern coast region. They were common at Magda- 

 lena Bay, where small flocks associated with willet and god- 

 wit; they were more plentiful along the estero on mud flats. 

 A male which was collected March 7, 1888, had commenced 

 to assume the summer plumage. 



84. Tringa minutilla VieilL 



Least Sandpiper. — Kecorded from Todos Santos (west 

 coast) by Mr. Ridgway in list of specimens collected by 

 Mr. Xantus. Mr. Anthony noticed them at San Quintin 

 Bay. At Magdalena Bay they were seen in small flocks and 

 specimens taken; also at lower Purisima canon. 



85. Tringa alpina pacifica (Coues). 



Red-backed Sandpiper. — I am not sure that I saw any of 

 this species at Magdalena Bay, and it does not appear on 

 the lists of either Messrs. Xantus or Belding from the Cape 

 region; the latter, however, mentions it as abundant at San 

 Quintin Bay, May 2, 1882, but rare by May 10. 



86. Ereunetes occidentalis La vr. 



Western Sandpiper. — Recorded from the Cape region by 

 Mr. Belding, and at San Quintin Bay where it was abundant 

 May 2, 1882, but rare by May 10, and on the northwestern 

 coast Mr. Anthony has found them. At Magdalena Bay I 

 saw a few in a flock of T. minutilla. 



87. Calidris arenaria (Linn.) 



Sanderling — One of the thirty-four species collected at 

 the Cape region only by Mr. Xantus. Mr. Anthony found 

 them very abundant all winter at San Quintin Bay. In 

 January, 1885, I collected specimens on the south end of 

 Cerros Islands, and obtained a single bird on Santa Mar- 

 garita Island March 4, 1889, from a flock of ^gialitis nivosa.
