NATURAL HISTORY. 
The porpoise, Fam. Delphinidoe, has the Delphinus Zea- 
landise, tujooupou , to represent it, which is as abundant in the 
southern seas as it is in the northern ; there are two kinds, 
the larger one with an elongated snout, and a smaller one 
without one at all. The natives describe a third, the TJpoho 
hue, a large kind. Of the Fam. Baloenidoe may first be 
noticed Physeter Macrocephalus, or sperm whale, the Cache- 
lot of Cuvier, Paraoa. It is the great fish of the south seas, 
and probably equals if not exceeds in bulk, though, perhaps, 
not in length, the monarch of the northern ocean ; it is cer- 
tainly by far the most valuable fish we are acquainted with, 
its ordinary length being eighty-five feet, and circumference 
thirty -five. It is found of different colors, some being white, 
others black, or of an ochreous or dingy red, and frequently 
of a mottled color. The sperm whale produces ambergris ; 
a single one contains upwards of a ton of spermaceti, or more 
than ten large barrels. 
The Baloena Antarctica, or right southern whale, Tohora, 
is usually from thirty-five to fifty feet long ; the baleen in a 
whale of forty feet, is nine feet long, and the oil averages ten 
tons. 
The Borqualus Antarctica Cuvier, Pajoate, or Balcenoptera 
Australis (Lesson, R.), the genuine character is the presence 
of longitudinal folds on the abdomen, it is said to possess a 
dorsal fin, the body is black above and white beneath, the 
folds when put aside, being of a pinkish color ; the oil 
is less in quantity, but finer ; the baleen also is too short to 
be of much value, this fish is very difficult and dangerous to 
capture,* it attains a length of thirty- three feet. 
The Baloena Gibbosa, or Humpback, f derives its name 
from the fleshy protuberances on its back, it differs only from 
the Mysticetus in being of less size, and in having these 
humps. Some of the humpbacks have yielded as much as 
seventy barrels of oil ; there are instances of this fish having 
two or three humps, but it is very rarely seen with more 
than two, one near the head and another near the tail, these 
whales are gregarious, and swim in shoals.
