69. Nycticorax nycticorax naevius (Bodd.) 

 Black-crowned Night Heron. ^A few were seen at Santa 



Margarita Island in the month of February, 1888. Ob- 

 served at the Cape region by Messrs. Xantus and Belding. 



70. Nycticorax violaceus (Linu.) 



Yellow-crowned Night Heron. — Common about Magda- 

 lena Bay. Many night herons were nesting in April, 1888, 

 in a mangrove thicket bordering the long estero; they all 

 appeared to be of this species. When alarmed by the pass- 

 ing of the sail-boat, they left the bushes and collected along 

 the water's edge, where I counted eighty. Mr. Belding 

 gives this species as occurring at the Cape region. 



71. Grus mexicana cMiill.) 



Sandhill Crane. — Mr. Belding has seen them in Tia 

 Juana Valley in winter and spring. 



72. Eallus beldingi Eidgw. 



Belding's Bail.— Found by Mr. Belding upon Espiritu 

 Santo Island, and at La Paz. Bails were heard in mangrove 

 swamp on Santa Margarita Island, Magdalena Island, and 

 for one hundred and twenty miles up the estero. They 

 were clapper rails, but whether R. beldingi I cannot say. 



73. Rallus obsoletus Ridgw. 



California Clapper Rail. — Found at San Quintin Bay 

 by Mr. Belding, also by Mr. Anthony, who mentions it as a 

 common resident of all salt marshes. 



74. Rallus virginianus Linn. 



Virginia Bail. — I believe this rail has not been previous- 

 ly recorded from Lower California, although occurring at 

 San Diego and in Mexico. Mr. Anthony has taken it at San 

 Quintin in winter. 



75. Porzana Carolina (Linn.) 



SoRA. — Barely seen in the vicinity of La Paz by Mr. Beld- 

 ing, but found in a marsh at San Jose del Cabo April and 

 May. Mr. Anthony has occasionally seen them in spring 

 along the coast north of lat. 31°
