HARELD. NATATORES. HARELDA. 365 



flattened, but it soon becomes narrower, and from thence to 

 about an inch above the labyrinth, is round and of equal 

 diameter. Its rings, then, are suddenly enlarged, but do not 

 again retain their perfect form ; the side next to the breast 

 being flattened and covered with a thin semi-transparent 

 membrane, divided into window-like portions by four fine 

 bony septa, or bars. The labyrinth consists of a large solid 

 bony orca, and a tympanum, whose transverse diameter is 

 much the longest. The above conformation was supposed to 

 produce the peculiar cry of this species, but without founda- 

 tion, it being well ascertained that the females, which are 

 without the tracheal enlargements, are as loud and singular 

 in tone as the male birds. The flesh of the Hareld is hard 

 and unpalatable, having a rank and fishy flavour from the 

 nature of its food.
