Station 244, 2900 fathoms. — One Lamna tooth, f inch (19 mm.) in length. 
Station 248, 2900 fathoms. — One Lmnna tooth, about an inch (25*4 mm.) in length, 
slightly coated with manganese. 
Station 252, 2740 fathoms. — One Carcharodon tooth, fully If inches (44‘4 mm.) in 
length, imbedded in the centre of a nodule, the layers of manganese around the tooth 
varying from ta f inch (12 '7 to 19 mm.) in thickness ; also four small Oxyrhina teeth 
imbedded in nodules. 
Station 256, 2950 fathoms. — Four Oxy^'hina teeth, the largest 1-g inches (38 mm.) 
in length, and five Lamna teeth ; three of the teeth were very deeply imbedded in man- 
ganese depositions. 
Station 274, 2750 fathoms. — One large Carcharodon tooth, fully 2 inches (51 mm.) 
in length, and broken piece of another large Carcharodon tooth, both deeply imbedded 
in manganese ; also nine Oxyrhina and five Lamna teeth, ^ the largest 1^ inches (38 mm.) 
in length, some deeply imbedded, along with several fragments of teeth and numerous 
small teeth of other fish. 
Station 276, 2350 fathoms. — Over 250 sharks’ teeth and fragments were counted 
from this station, including four large Carcharodons, from 2 to inches (51 to 64 mm.) 
in length, and fragments of similar large teeth ; fourteen smaller serrated teeth,^ similar 
to Corax or Carcharias; sixty teeth like Lamna, ^ of various sizes, the largest 1^ inches 
(38 mm.) in length ; thirty Oxyrhina teeth, the largest, Oxyrhina trigonodon,^ \\ inches 
(38 mm.) in length; fifteen teeth which may possibly be the central fangs of Otodus ; 
and over one hundred small teeth, less than inch (12'7 mm.) in length. The majority 
were more or less deeply imbedded in manganese. There were also two tabulated teeth 
of Tetradon, and four large otoliths of fish, similar to those of the Tunny. 
Station 281, 2385 fathoms. — 116 sharks’ teeth and fragments were counted from 
this station, including' eleven Carcharodons, one, the largest obtained during the cruise, 
being fully 4 inches (10 cm.) in length, belonging to- Carcharodon mcgalodon,^ the 
others 2 inches (51 mm.) and less in length;^ and over one hundred teeth of Oxyrhina, 
Lamna, &c., the largest 2 inches (51 mm.) in length.'^ Most of the teeth had a slight 
coating of manganese, while a few were deeply imbedded; 
Station 285, 2375 fathoms. — Over 1500 sharks’ teeth and fragments of consider- 
able size were counted from this station, in addition to immense numbers of very 
small teeth and fragments. There were fifteen nearly perfect Carcharodons,^ the largest 
3 ^ inches (83 mm.) across the base and 2^ inches (64 mm.) in length, and about twenty 
fragments of similar teeth ; twenty small teeth, like Corax or Galeus or Hemipristis ; ^ 
about two hundred perfect Oxyrhina and Lamna teeth of various sizes, in addition to
