APPENDIX. 
On an earlier page of the present paper I referred to the 
species described below, and remarked that I only knew of 
its existence through the medium of the ** Zodlogical Record ” 
for 1901; since then, I have, however, received a complimentary 
copy of the paper in which it is described, from its author, to 
whom I take this opportunity of returning my grateful thanks, 
By his courtesy I am not only able to add to the description 
of this new species, but also to add Emydura Kreffii to the 
fauna, and so complete the list of New Guinea chelonians to 
date. Appended is a translation of Dr. Werner’s original 
description. 
CHELODINA SIEBENROCKI. 
Chelodina. sicbenrocki, Werner, Verh. z06l].-hot. Ges. Wien, 1901, p. 602, 
Dutch New Guinea. 
Intergular shield 14 time as long as the suture between 
the pectorals, twice as long as wide. Plastron somewhat less 
than twice as long as wide. Pectoral shields much longer 
than any single median suture of the plastron, 14 time as 
long as the femoral suture, and 24 times as long as that of the 
abdominals : anal suture somewhat shorter than the femoral 
shield. Head very long. nearly twice as long as wide, little 
shorter than half of the plastron. Skin behind the eyes 
tesselated, but smooth along the median line, the spaces mostly 
longer than wide. Lower jaw, especially at the symphysis, 
much more feeble than in Chelodina nove-guinee, only one 
third as wide as the diameter of the eye ; on one side two very 
small barbels are present. Seven or eight wide, band-lke 
lamellze on the front of each fore leg. Above black, below 
dark brown. Hinder costal and vertebral shields longitudin- 
ally striated nearly to the border of the carapace. Nuchal 
shield rectangular, 1} time longer than wide. First vertebral 
shield the largest, fifth the smallest, six present, as in 
Chelodina nove-guinee. (Named for Dr. Friedrich Sieben- 
rock).
