229. Podiceps griseigena. Red-necked Grebe. 

 I observed this species in small numbers on the lagoons 

 near Puerto Alcudia in November 1921. 



Included by v. Jordans on Barcelo's authority. 



2.30. Podiceps auritus. Eared Grebe. 

 Included in y. Jordans' list. 



2.31. Podiceps nigricollis. Black-necked Grebe. 



This sjjecies frequents the higoons in the neiohbourhood 

 ol Puerto Alcudia during the winter in small numbers, and 

 though they do not remain to breed on these pieces of water, 

 they probably remove to the Albufera adjoining for that 

 purpose. 



232. Podiceps ruficollis. Little Grebe. 



Not uncommon in suitable localities ; there were numbers 

 in the Albufera all the year which strayed on to the 

 adjacent lagoons during the winter. 



The Grebes, when attacked by Marsh-Harriers, dive 

 hurriedly, splashing the water high into the air, possibly 

 with the idea of driving off their pursuer. 



233. Rallus aquaticus. Water-Rail. 



Fairly plentiful in suitable localities all the year. 

 Obtained l)y v. Jordans. 



234. Porzana porzana. Spotted Crake. 



Nearly as plentiful as the last-named, and a good many 

 are shot in the autumn. 



Included in v. Jordans' list on Barcelo's and Homeyer's 

 authority. 



235. Porzana pusilla. Baillon's Crake. 



236. Porzana parva. Little Crake. 



Von Jordans includes both these species in his list. 



237. Crex crex. Corn-Crake. 



Included by v. Jordans on Barcelo's authority.
