196 REY. O. P. CAMBRIDGE ON [ Mar. 16, 
Ericone porsvosa, sp. n. (Plate XXVII. fig. 6.) 
Adult male, length ? line. 
The cephalothorax of this Spider is of a pale dull yellowish colour 
slightly tinged with green ; it is short, rather flattish, and of a some- 
what uniform convexity, the occiput, however, being rather gibbose, 
but not suddenly elevated; the summit of the gibbosity is furnished 
with a few very short hairs, and the profile line from the summit 
forms a slight but continuous curve; on each side of the summit is 
a large, longitudinal, strongly marked indentation or excavation; and 
the normal thoracic indentations appeared to be marked by conver- 
ging lines of very small punctures. 
The eyes are in two transverse lines or four pairs, as nearly as possi- 
ble halfway between the lower fore margin of the caput and its summit ; 
they are of ordinary size, those of the hind central pair are separated 
from each other by the distance of an eye’s diameter, and are nearer 
together than each is to the the hind lateral on its side; those of the 
fore central pair are smallest of the eight, contiguous to each other, 
and each is separated from the hind central eye nearest to it by the 
diameter of the latter ; those of each lateral pair are obliquely placed 
and coutiguous to each other, each being separated from the fore 
central eye on its side by an interval rather greater than that which 
divides the latter from the hind central eye nearest to it. 
The legs are short, slender, of a pale dull yellowish colour, furnished 
pretty thickly with hairs, and a few fine erect bristles on the upper 
sides ; their relative length appeared to be 4, 1, 2, 3. 
The palpi are short, of moderate strength, and similar to the legs 
in colour ; the cubital joint is larger at its fore than at its hinder ex- 
tremity ; the radial is shorter and has its fore extremity expanded, 
with a prominent but short curved point about the middle and a short 
truncated projection on its outer side, on the margin near which is a 
row of strong bristly hairs ; the digital joint is not very large, of an 
oval form, with a boldish prominence at the middle of its outer mar- 
gin; the palpal organs are well developed and moderately complex, 
at their outer extremity is a black tapering spine coiled in a circular 
form, and its prominent point is very close to that of another fine 
black spine which springs from within the coil of the other. 
The falces are of moderate length and strength, and project a little 
forwards ; they are armed with a row of very minute teeth on their 
inner margin forwards, and, like the mawille and labium, are similar 
in colour to the cephalothorax. 
The sternum is of a dull blackish colour mixed with pale yel- 
lowish, very convex and glossy, and marked thinly with minute 
punctures. 
The abdomen is oval, but of a somewhat cylindrical form, and does 
not project over the base of the cephalothorax ; it is of a dull blackish 
colour, and (in spirit of wine) thickly mottled with pale yellowish 
points and some transverse angular lines in a longitudinal series on 
the hinder half of the upperside; the colour of the spinners is 
similar to that of the legs. 
An example of this minute Spider was sent to me in 1874 by M.
