The discovery of two specimens of Lingula in late Tertiary strata of Antarctica 
is interesting. It would appear that it is a new record so far as the Tertiary strata 
of adjacent circumpolar regions is concerned (South America, Australasia) — at least 
the literature searched has not given any result. Further, according to its present 
distribution. Lingula (and Glottidia) is decidedly a warm-water genus — not being 
found far outside tropical seas: it ranges from about Lat. 37 N to about Lat. 28 S. 
When, therefore, specimens of Lingula are obtained from strata so far south as 
above 64° Lat. it would suggest that at the time these strata were laid down the 
temperature of that southerly latitude was, perhaps, about that of Korea at the 
present day. And yet this time cannot have been so very much before that of 
the maximum glaciation, the date of which Dr. J. GUNNAR AnderSSON (p. 70) 
places in the second period after the formation of the Pecten conglomerate, which 
is younger than the Lingula rock. 
The alternative suggestion is that these Lingulœ have been drifted southwards. 
Against this supposition two reasons may be urged — ist., that the shells are not 
worn; the one in the block is very sharply preserved; 2nd., that the Antarctic Drift 
current sets northwards from Graham Land. 
The next Table (III) shows the distribution of the Antarctic species or their near 
allies in the strata and seas of the countries which lie around the South Pole: that is 
to say in New Zealand, Australia (and Tasm,ania) and southern South America. 
South Africa seems to afford no help in regard to fossil, and little in regard to 
recent species.
