I have just been shown (January, 1877), but too late for description in the text, a 

 very characteristic left upper molar, almost entire, by Professor Ramsay, F.R.S., Director- 

 General of the Geological Survey, who lately discovered it in a marine deposit near the 

 sea-gate of Tangier. It is of the narrow-crowned variety, like the tooth from Gibraltar, 

 which was also found in a marine deposit.
