130 DR. T. THORELL ON SPIDERS FROM NEW [Mar. 2, 
5. On some Spiders from New Caledonia, Madagascar, and 
Réunion. By T. THorext. 
[Received February 24, 1875.] 
(Plate XXV.) 
Some considerable time ago I received from Dr. Aug. Vinson, the 
celebrated author of ‘ Aranéides des files de la Réunion, Maurice et 
Madagascar,’ ‘ Voyage 4 Madagascar au couronnement de Radama 
II.,’ &c., a little collection of Spiders, partly from New Caledonia and 
partly from Madagascar and Réunion, among which were a few new 
species which Dr. Vinson requested me on a fitting opportunity to 
describe. The collection was accompanied by beautiful figures of some 
of the species sent, executed by Dr. Vinson himself, and by various 
interesting notices relative to their habits, which Dr. Vinson obligingly 
placed at my disposal. Hindrances, which it was not in my power 
to avoid, have prevented my executing the commission thus received 
as early as I could have wished. Having, however, now obtained 
leisure for the purpose, I have not confined myself to describing 
those species only which appear to me to be new, accompanied by 
the figures I have received from Dr. Vinson, but I have also added 
more or less detailed descriptive notices of the other previously known 
species. Dr. Vinson’s work, ‘Aran. des Iles de la Réunion &c.,’ has, 
as is generally known, met with a large and universal approval, and 
is justly considered one of the most valuable works treating on this 
interesting group of animals, especially on account of the numerous 
and important observations it contains relative to the habits and in- 
stincts of the species described. The species of which he has treated 
nave, through these observations as well as through Dr. Vinson’s 
descriptions and figures made directly from living specimens, become 
of the greatest interest to European arachnologists, who are seldom 
able to learn more about the life of extra-European Spiders than the 
name of the country where they are met with, or to see other than 
more or less faded specimens preserved in spirit. Having now had 
the good fortune to receive original specimens of some of Dr. Vinson’s 
species, I consider myself bound to avail inyself of this opportunity to 
indicate the changes of colour that some of them undergo when (as 
is the case with the specimens I have received from Dr. Vinson) they 
have lain some considerable time in spirit, as also to make some 
additions to Dr. Vinson’s descriptions, and thus to offer a little con- 
tribution to our knowledge of these Spiders. 
The species in question are as follows :— 
NEPHILA LABILLARDIERU, n.sp. (Plate XXV. figs. 1, 2.) 
Cephalothorace paullo breviore quam tibia cum patella quarti paris, 
nigro, bituberculato, pube dexsa subargentea tecto; sterno tuber- 
culo magno nigro pone labium instructo, tuberculis*lateralibus eo 
minoribus, rufescentibus ; oculis lateralibus spatio diametro sua 
plus duplo majore disjunctis ; pedibus obscure testaceo-fuscis,
