drill.—Explanatory note on Glossopteris and Gangamopteris. 
I wish to make a few remarks explanatory of some statements in my paper on the 
homotaxis of the Gondwana system.* I do so at the request of Mr. W. T. Blanford, and 
most willingly, as it may explain some misunderstandings which I never intended. 
Both these statements are on page 122. The one refers to the occurrence of Glossop- 
teris in Australia. When I said that there would with great difficulty be found one species 
common with our Damudas, I referred to the lower beds, because, as far as I know the fossils, 
it is so ; while with the upper beds (I mean those without animal fossils) there will be more 
species identical. My contradiction referred, therefore, to the identity of species of Glossov- 
teris in the Damudas and lower coal-beds in Australia. 
The second statement which I have to explain is about Gangamopteris, which Mr. W. T. 
Blanford mentioned as having been detected by me in the lower coal-beds in Australia. I 
must confess that from a cursory inspection a specimen seemed to me to be Gangamopteris, 
and I mentioned this determination to Mr. Blanford, without, however, the intention 
of having it published. Wheu Mr. Blanford published this determination, which after¬ 
wards proved wrong, I had to contradict it, but omitted to say that the fault was on my 
side, as the determination was only a superficial one and not corrqct. 
Notices of new oe bare Mammals from the Stwaliks, by R. Lydekker, b. a.. 
Geological Survey of India. 
Since my last notice of Siwalik Mammals, Mr. Blanford has sent from the Manchhar 
(Siwalik) rocks of Sind a small, but very interesting, collection of mammalian teeth ; 
among the species in this collection the following are new to the Sind area, viz .:— 
Sanitherium Schlagintiveitii, Meyer. 
Chceromeryx silistrensis, Pentland, sp. 
Hyopotamus palaindicus, sp. nov. nobis. 
Merycopotamoid, gen. non. det. 
Sus hysvdricus, Pale. and Caut. 
Aceroikerium perimense, Falc. and Cant. 
Amphicyon palceindicus, nobis. 
Of the most important of these specimens I now give short notices, preparatory to 
fuller descriptions and figures; in the present paper I have also noticed specimens of the 
teeth of two genera of Mammals new to the Siwaliks, collected by Mr. Theobald in the 
Punjab; the upper molars of a new genus of Siwalik Hippopotamoid are also shortly 
described ; as well as two lower molars of what appears to be a new species of Trilophodont 
Mastodon. 
ARTIODACTYLA. 
Sanitherium Schlagintweitii, Meyer. 
This genus has been hitherto known only by some molar teeth of the lower jaw, from 
Kushalghar, which will be found figured on PI. 9 of “ Indian Tertiary and Post- 
Tertiary Yertebrata :”f among Mr. Blanford’s collection there are two upper molar teeth
