THE DEPTH AND MARINE DEPOSITS OF THE PACIFIC OCEAN. 89 
otic of Kogia or some very similar form, and 1 indeterminate long and 
slender bone. Most of these remains are but slightly encrusted with 
manganese. 
“Station 4658, depth 2370 fathoms. Four teeth of Oxyrhina, 9 Lamna, 2 
nondescript fragments; also 1 delphinoid tympanic. Manganese coating 
very slight. 
“Station 4666, depth 2600 fathoms. No fish remains; 4 excellently pre- 
served ear-bones of Hyperoodon, one having the tympanic still fused with the 
periotic ; also 1 heavily encrusted delphinoid tympanic, and several corroded 
osseous fragments. 
“Station 4676, depth 2714 fathoms. No fish remains; 3 rather heavily 
encrusted ear-bones of Hyperoodon, . . . and 1 unrecognizable fragment. 
“ Station 4685, depth 2205 fathoms. This station, which lies within the 
barren area, is remarkable for having furnished a larger number of vertebrate 
remains than any other during the cruise, and with them were brought up 
15 tons of manganese nodules. There are in all 73 sharks’ teeth, 5 of 
which belong to Carcharodon; the rest to Lamna and Oxyrhina. Some of 
the teeth are embedded in nodular masses; none have the crowns heavily 
encrusted, but the majority have dark-brown clay adhering to them. 
Cetaceans are represented by 5 delphinoid ear-bones; the tympano-periotic 
of one individual consists of a single piece. 
“Station 4693, depth 1142 fathoms. According to the published record 
of ‘ Albatross’ dredging stations, in the General Report of the Expedition, 
sharks’ teeth and cetacean bones came up in the trawl at this locality. 
None such are contained, however, in the collection submitted for examina- 
tion, the only specimen marked with this station number being a well 
preserved tergum of Lepas. 
“Station 4695, depth 2020 fathoms. The vertebrate remains dredged 
at this point are confined to 2 small and tolerably fresh-looking Oxyrhina 
teeth. 
“ Station 4701, depth 2265 fathoms. Hight sharks’ teeth, including 1 large 
and beautifully preserved Carcharodon, wholly unencrusted, also 1 large and 
6 smaller Oxyrhina teeth, very lightly coated ; 2 delphinoid ear-bones, like- 
wise with very little coating. 
“Station 4709, depth 2035 fathoms. Two small fresh-looking Lamna 
teeth; 2 heavily encrusted ear-bones of Hyperoodon, 1 indeterminate
