and are now in charge of Mr. F. \V. Pennj’, geologist of that or- 
ganization. To him science owes a great debt for the loan of 
these unique copies, that the reprint may be made directly from 
the original without the dangers of mistakes and the loss of time 
involved in having all these articles typewritten. 
Guppj-’s latest publications, of the class here concerned, ap- 
peared in the Proceedings of the Agricultural Society of Trini- 
dad and Tobago. But even these are quite difficult to obtain, 
being quite generally “out of print.’’ Through the efficient as- 
sistance of Mr. G. A. Waring of the Trinidad Petroleum Devel- 
opment Company, by going the rounds of the libraries, public 
and .semi-private, practically all of Guppy’s paleontologic pax^ers 
have been assembled, though in one case a typewritten copy had 
to be made of the only coi^j’ found. 
Of the fort5'-one articles referred to below, twentj'-five are 
herewith republished as being now quite inacces.sible to paleonto- 
logical workers in the best equix^x^ed laboratories. 
In the various papers reprinted the subject matter is given 
X^age for page, w’ith the original orthograph}’, unle.ss otherwise 
indicated. The punctuation and capitalization in some of the 
later papers become extremel}’ erratic, yet it has seemed best to 
adhere strictly to “cop}*’’ lest Gux)p3’’s intentions should be 
slightly modified b}’ corrections introduced. 
The diagrams illustrating geologic .sections have often been 
reduced in size since nothing is to be gained b}’ large cuts while 
smaller ones show clearl}' all details. 
On plate 7, fig. i, no attempt has been made to color the 
carapace of Raniiia cuspidata 3-ellow as was done in the original. 
Guppy' s bibliographical notes on the geolog}’ of the West 
Indies are mainly recorded below in the Synopsis, pp. 7 and 193, 
from the Transactions of the Canadian Institute. Additional 
and supplemental references are given in his paper on Some Re- 
cent Geological Discoveries in the West Indies, reprinted in this 
Bulletin as PAPER No. 22, px^. 178-178.
