Descriptions of some New Species of Pycnogonide. By Henry 
D. S. Goopsir, Esq. Read before the Wernerian Society, 
March 1841. Communicated by the Author. (With a Plate.) 
Class, Crustacea.—Sud-Class, HausTELLATA. 
Order, ARANEIFORMES. 
Genus I. Phoxichilidium (Orythyia, Johnston). 
Species 1. Phozichilidium globosum (Mihi). Rostrum a little 
longer than the first joint of the mandibles ; eyes large and 
shining; fourth articulation of the ambulatory legs very 
much dilated ; no spines on the eighth joint of the leg; 
whole body covered with fine hairs. 
The whole animal is of a light pea-green colour, of a robust 
form, and covered with fine hairs, which are thickest on the 
legs. The rostrum is shorter and thicker than in the other 
species of this genus. The mandibles lie on the upper sur- 
face of the rostrum, so as to hide it, and are hispid. The 
oculiferous tubercles are prominent, situated immediately be- 
hind the origin of the mandibles, and bear four black shin- 
ing eyes. The three first joints of the ambulatory legs are 
equal; the fourth very much dilated, almost spherical ; first 
and second tibial equal; first tarsal joint minute, second equal 
to the two first coxal, and bearing no spines on its inferior 
surface, but armed with a strong claw. The length of the 
body rather more than half a line ; span of the legs three lines. 
This species is easily distinguished from the Orythyta ece- 
cinea of Dr Johnston, by the eyes being quite distinct, black, 
and covered with punctures. The most prominent characters, 
however, are the extreme dilatation of the thigh joint, and the 
absence of the spines on the inferior surface of the second tar- 
sal joint.
