jische of Anderson and some other whalers is added, and proba-— 
bly from them is taken the following note: “ Bellum gerit cum — 
Phocis, quas ope gladii dorsalis e lapidibus detrudit ; Balenarum — 
Phocarumque tyrannus, qua turmatim adgreditur. Pinna dorsalis 
est spina ensiformis, sex pedalis, cute vestita, basi latior.’—Mant. ~ 
ii. 523. Bonnaterre gave the name of Delphinus gladiator to 
Anderson’s figure, which represents the dorsal fin as situated near 
the nape. 4 
Cuvier believed that the Orca of the ancients was probably a — 
Cachalot, and that the Killer is the Aries marinus of Pliny, Ahan — 
and the Latins, who compared the white streak behind the eye to — 
a horn. Desmarest, Mam. 515, confines the name Delphinus 
Orca to the animal intended by the ancients, and characterizes it 3 
—“ Museau conformé comme celui de Dauphin vulgaire; dents 
larges et crenulées sur leurs bords,” being a translation of Ar- 
tedi (Gen. Piscium, 76, 3), “ D. rostro sursum repando, dentibus | 
latis serratis.”” 
O. Fabricius observes that he never saw D. Orea; but Prof. 
Eschricht believes the Physeter microps of O. Fabricius to be the 
Killer, or D. Orca of Linneus (Dan. Trans. xil.).
