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. ‘Che 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.
