1s Species is no doubt closely allied to Thomisus tripunctatus, 
Lucas*; but I do not think that it is identical with that West-A frican 
species. In Th. tripunctatus, according to Lucas, the cephalothorax 
is prolonged on either side anteriorly (between the lateral eyes) into 
‘*a very sharp spine,” the mandibles are constricted or sinuated on 
the outer side towards the apex, and the third pair of legs are longer 
than the fourth pair &c., which is not the case in the above-described 
Spider from Madagascar, kindly sent me by Dr. Vinson. 
In naming this Spider after Dr. Vinson I only utter a feeble ex- 
pression of my respect for his scientific merits and my thankfulness 
for the kindness he has shown me.

The colour of this beautiful Spider is much changed in examples 
preserved in spirit of wine; the cephalothorax is of a dull and pale 
olive-green colour, the pars cephalica being limited posteriorly by a 
large \/ of a paler yellowish tint. The legs are yellowish brown, 
somewhat paler towards their base, brownish black at the extremity; 
the trochanters are blackish ; the thighs and patelle have a narrow 
blackish ring or spot at the apex. ‘The abdomen is greenish, with a 
brownish band along the middle of the back; this band is limited 
on either side by a whitish band or line, which anteriorly, towards 
the base of the abdomen, is continued by a series of about four un- 
equal, somewhat oblique, whitish spots. The olive-greenish belly 
shows two longitudinal yellow bands or lines, the space between these 
bands being of a darker brownish tint. The two small fore eyes are 
separated from each other (and from the large middle eyes) by an 
interval equalling their diameter; the interval between the large 
(fore) middle eyes is evidently greater than their diameter, but 
scarcely greater than the interval between them and the hind lateral 
eyes. The area of the four central eyes is about one fourth larger in 
front than behind, as long as broad in front; the fore central eyes 
are separated from the hind centrals by an interval about double as 
great as the diameter of the largest eyes. The hind series of eyes 
is slightly curved forward; these eyes are nearly of the same size (the 
centrals, however, slightly larger than the laterals), and are separated 
by nearly equal intervals, at least as great as the diameter of the 
hind centrals. The height of the clypeus is somewhat greater than
