teen. From what I have observed, this appears to 
be a much smaller tree than the true touckpong, 
but it has larger and coarser leafage. In fruit 
they appear to me, judging from memory, to quite 
agree, and in all the other essential botanical characters 
that I have been able to compare. Yet judging from 
the leaf and fruit alone, Professor Oliver is disposed 
to regard the Pomeroon touckpong, as quite distinct, 
and possibly new to science. However, the touckpong 
belongs to the great order Euphor-biacae-spurge- 
worts, — not to Moreae, to which I conjectured, from a 
sight of leaves alone, in my former report that it might 
belong. In that report I mentioned cumakaballi as the 
Arawack name for this tree ; but from recent investiga- 
tion, I feel some uncertainty as to whether the touck- 
pong is really included with the several plants to which I 
find that name is applied both on the Pomeroon and 
Essequibo Rivers. I am rather disposed to believe that 
it is not, from the fa6l, ascertained by Mr. IM THURN, 
that on the Pomeroon, the Caribisi Indians ascribe 
several plants, all, or nearly all, of which, are figs, to 
cumakaballi, while for Sapium biglandulosum, or, what- 
ever it may prove to be, they use the term touckpong 
specially. The Arawak Indians of that region call 
the latter hya-hya, but this further confuses the matter, 
as that is the Indian name of the cow tree — Tabernae- 
montana utilis — which is quite a different thing and has 
no gum in its copious milk. Cumakaballi is undoubtedly 
a fig. From what I could gather on my late visit to the 
Essequibo River, Cumakaballi seems to be used in a 
generic sense to embrace, at least, all the larger growing 
species of fig-trees, but apparently not the touckpong.
