376 THE “ HORRIBLE SEA-SATYRE ” CHAP. 
Grey Whale. “ Belua truculenta dentibus,” observed Olaus Magnus 
of this Cetacean. The high dorsal fin has been much exaggerated 
in old drawings; it has been even represented as strong and 
sharpened at the end, so as to be capable of ripping ‘open the 
belly of a Whale. The fact that it sometimes lies over a little 
to one side is responsible for another anecdote: that an example 
of this Whale was seen to retire with a couple of Seals tucked 
away under the flippers, another grasped by the dorsal fin, and a 
fourth in the mouth! “When an Orca pursues a whale,’ wrote 
Dr. Frangius, “the latter makes a terrible bellowing lke a bull- 
when bitten by a dog.” It is probable, according to F. Cuvier, 
that this Whale is the “ Aries marinus” of the ancients, certain 
bands of white upon the head giving an impression of curved 
horns. It may also be the “horrible Sea-satyre” of Edmund 
Spencer. 
Allied to Orca, but distinguishable from it by some rather 
minute peculiarities, is Psewdorca. It may be thus defined :— 
Teeth eight to ten, much like those of Orca. Dorsal fin 
rather small, faleate. Vertebral formula C 7, D 10, L 9, Ca 24. 
Six or all the cervicals united. The curious fact about this 
Whale, which embraces only a single species, P. crassidens, is that 
it was first known in the fossil condition from remains discovered 
in the fens of Lincolnshire. An important day for cetologists 
was that on which a whole herd entered the Baltic and furnished 
material for a better study of this Whale. It is not, any more 
than its near ally Orca, confined to northern seas; for several 
examples, at first relegated to a distinct species (P. meridionalis), 
have been obtained from the seas round Tasmania. 
Orcella (which has been written Orcaella) has fourteen to 
nineteen small sharp teeth in each half of each jaw. The 
pterygoids are widely separate. The dorsal fin is small and 
falcate. The vertebral formula 1s C 7, D 14, L 14, Ca 26. 
Seven ribs are two-headed, and five of them reach the sternum. 
This genus contains but a single species, O. brevirostris, which 
is both marine and fresh-water in habit; it occurs in the Indian 
seas, and in the Irrawaddy even as far up as 900 miles from the 
sea. Some regard the fresh-water individuals as a distinct form, 
O. fluminalis. 
Sagmatias is a genus known only from a skull, which is 
remarkable for the elevation of the premaxillae into a crest; the
