144. DR. T. THORELL ON SPIDERS FROM NEW (Mar. 2, 
are armed with tolerably numerous spines, which are very long and 
appressed on the underside of the tibize and metatarsi: the thighs 
of the first pair of legs, for instance, have above 1, 1, before and 
behind 1, 1, 1, beneath 2, 2 spines; their patella has one spine 
behind, the tibia and metatarsus before and behind 1, 1, beneath 
2, 2 spines, the tibia, moreover, one spine above. The tarsi are fusi- 
form, convex longitudinally above ; their underside, like that of the 
anterior metatarsi, is provided with a scopula. 
This species must probably be removed from Heteropoda (Latr.), 
Thor.* (of which genus dranea venatoria, Linn., Olios leucosios, 
Walck., is typical), and should perhaps be made the type of a 
separate genus.

It is very uncertain whether this species be the true ‘‘foka” or 
“ fook”’ of the natives of Madagascar ; as to their opinions regarding 
the venomousness of that redoubted Spider vide Vinson, Aran. de 
la Réunion, &c. p. 71. But in his letter to me Dr. Vinson says :— 
« Depuis mon voyage 4 Madagascar, j’ai des doutes sur les qualités 
vénéneuses qu’on préte a cette araignée. Je l’ai trouvée a la Réunion 
(la méme) fort inoffensive. La fameuse Foka ou Fouque, comme 
disent les Malgaches, serait le fameux Hresus guérini qui habite 
aussi l’Algérie. C’était ma premiére opinion par analogie de contrée 
et de voisinage géographique, et j’y reviens. Je n’ai pu jusqu’a 
présent toutefois approfondir cette question.” 
The specimen sent me by Dr. Vinson, an adult female, is from 
Madagascar. Its colour is dark reddish brown, with exception of 
the tibize, metatarsi, and tarsi, and the tibial and tarsal joints of the 
palpi, which parts are of a bluish black colour. The structural 
details contained in the following description may in*some degree 
serve as a complement to that given by Dr. Vinson.
