between Carcoar arid Orange, by the Eev. W. B. Clarke, 
M.A. Fruits, which constituted probably separate carpels of a 
tricoccous fructification from two-thirds to ratlier above 1 inch 
long, externally uneven from somewliat irregular slightly con- 
centric ridges, which are often broken up into sliort tubercules, 
approaching in roughness somewhat to those of Phymatoearyou 
Mackayi, probably covered originally by a pulpy pericarp, which 
in decay would early perish, thus the nut-like covering consti- 
tuting a putamen or endocarp ; a very faint cleavage at the base, 
but no trace of valvular dehiscence ; septal process from less than 
double to iiearly triple the width of the walls of tlic endocarp, 
except the base and back free from tlie cavity. Seeds (in 
all specimens under examination) perished, but their form recog- 
nized from the space left for their reception between the dissepi- 
ment and the inner faces of the endocarp ; remnants of the testa 
not showing any indications to intrusions into the albumen. The 
latter and the embryo unknown. 
“ This new fossil, so fai' as I can judge from the material trans- 
mitted to me, brings before us for the first time with certainty a 
member of the ^lehispermeoe among the vegetation of bygone 
creations, inasmuch as of this order hitherto only the altogether 
doubtful genus Mac Clintockia {TIeer die Fossil e Flora dev Folar- 
lander, 111-116 ; Scliimper, Traitd de Palcontologie Vegetate^ iii, 
83-81 pi. xcviri) became palgcoutologically recorded. Unac- 
quainted as we arc with the flowers and the embryonic characters 
of the fruit, we must regard it unsafe to place this into any of the * 
numerous genera of Menispermcic, distinguislied mainly by their 
floral organization and the inner structure of their fruit ; hut the 
cndocarj) and septal x»i'otuberance show some resemblance to the 
South Asiatic genera Ilypserpa (Miers, in Annals of Natural 
History, sic. ser. vir, 10), Limacia audNephroica {Laarelro Flora 
Cochinchinensis, Q20 et 692), and the East Australian Sarcopet- 
alum (E. M., Plants indigenous to the Colony Victoria i, 27, jil. 
IIT, suppl.) The putamen, however, is more rough than that of 
any of these genera, and indeed conspicuously thicker than that 
of any living menispermaceous plant known to me, while in its 
great size the fruit of Ehytidocaryou shows only similarity (and 
in thk respect merely) to Hicmatocarpus (Miers’s Contributions
