Thu plant structures, although obscure, are also important, A leaf¬ 
like body baa boon referred to Padozamiles of. lanceolatm (Lindley it 
Hutton), a genus and species which, enjoyed an extensive geo* 
graphical distribution during tbe Bajooian stage of Jurassic times, 
having been recorded from Yorkshire (Haibum Wyke); Spitz- 
bergen; Orenburg; East Siberia; Astrabad, Persia; India (Upper 
Good wans Beds) ; China ; Japan ; and Korea. 
Podiianmifc* is but one member of a large group of similar plants, 
generally included under tbe CycadaoeGB, which were of abundant 
ooourrence in tbe Mesozoic period, and of which TFiHiama&riia may 
be regarded as tbe type. Snob a flora has been described by 
Fa it; tin anted as typical of the Upper Gondwana deposits of India, 
and it is of further interest to note that marine molluecfin remains 
have been also found m some of those beds associated with ihe 
plants (H. D. Oldham’s edition of Merilicott & Blau ford's “ A Manual 
of tbe Geology of India/ 1 1SD3 + p. 160), 
The Singapore Clays, therefore, with their estuarine contents, may 
be of Middle Jurassic age, and about the horizon of the Inferior 
Oolite of England or the so-called Bajooian of Continental geologists. 
They possibly represent an extension or outlier of tbe Upper 
Gondwana rocks of India, as well as forming part of the other 
fossiliferous areas of Eastern Asia* including Korea* Japan, and 
Siberia, which have yielded a similar vegetation, 
Mr. John B, Sorivenor, the discoverer of these fossils, has 
furnished the following account of the beds and locality, stating 
that the specimens were obtained " from a 2 ft. (ciVcd) bed of silly 
clay with obscure pi ant-remains, forming a part of the series of 
shale and sandstone beds which embraces all the known sedimentary 
rocks of Singapore Island apart from aurfuoe deposits, and exposed 
in a big quarry on the north flank of Mount Guthrie, Tanjoug 
Pagar, Singapore Town. 
M Wlmt remains of Mount Guthrie is likely to disappear before 
long; m fact, the original hill extended over the spot where I found 
tbe fossils. The specimens take some time to collect, as they arc 
sparsely distributed. I send the best fossil leaf I could find and 
also an object which may be a fruit I also saw obscure vegetable 
remains in shale at Tonjong Malang, close by; and at Mount 
W&llich* also close by, I saw one piece of badly-preserved fossil 
wood. In the Mount Guthrie quarry, about 50 wards from the 
fossiliferous horizon, I found a 6 inch seam of very poor brown coal, 
“Tb* shale and sandstone series is very highly inclined in this 
part of Singapore; in cue section I saw the beds are vertical. At 
Mount Guthrie the strike is N.N.W.-S.S.E,, the dip about 76° W.S.W. 
“The strike and petrological characteristics of the series wherever 
seen suggest a connection with the shale and sandstone of the 
Federated Malay States; but, again, were these rocks situated in 
Sarawak [Borneo] the petrological evidence and the presence of the 
obscure vegetable remains would not be sufficient alone to separate
