EURYOPIS.—DOLICHOGNATHA. 147 
The sternum is large, very glossy, convex, heart-shaped, its posterior extremity rather drawn out, and ending 
in an obtuse form between the posterior coxee; its colour is dark yellow-brown. 
The abdomen is rather large, oval, somewhat flattish ; it is of a deep brownish colour; the upperside is thickly 
furnished with small reddish-brown shining tubercles or granulations, to each of which is articulated a 
long, prominent, straight, sharp-pointed, pale-coloured spine. The underside is dark reddish-yellow- 
brown, the anterior portion, as well as some patches of the hinder part, are of a somewhat coriaceous 
nature. 
The colours of the abdomen can scarcely be relied upon, as the spider had apparently been allowed to get dry 
and again put into spirit. The spinous abdomen, however, is very characteristic.

DOLICHOGNATHA, Cambridge. 
Dolichognatha diversa, Sp. n. 
Adult female, length 1 line (to spinners); height of abdomen nearly 1 line; breadth of abdomen ? of a line. 
Cephalothorax rounded behind ; caput large, raised, prominent, occiput well rounded ; colour yellow, with a 
strong, transverse, irregular, somewhat angulated, black-brown band a little behind the eyes; from 
this band two curved blackish lines run backward, one on each side of the occiput, their posterior ends 
converging but not touching and somewhat bifid, and near the margin of the thorax on each side close 
to the junction with the caput is a short linear black spot. The ocular area slopes a little downwards, 
and the height of the clypeus is about equal to the diameter of one of the fore-central eyes. 
Eyes occupying a considerable area on the whole width of the caput, seated on strong black tubercles, that of 
the fore-central pair strongest and forming one prominence ; they are placed in two transverse rows, 
the posterior row very slightly curved, the convexity of the curve directed backwards, the anterior row 
more strongly curved and in an opposite direction. It is difficult to judge accurately the distance between 
the eyes; they are seated variously on tubercles, but those of the anterior row appear to be about equally 
separated. The interval between those of each lateral pair is equal to that between the hind-lateral and 
hind-central eye on each side, The hind-centrals are smallest and contiguous to each other, and the 
fore-centrals are largest. 
Legs rather short, tolerably strong, 1, 2,4, 3. Those of the first two pairs much the longest and strongest. 
The tibie gradually strengthen from the middle to the fore extremity. Their colour is yellow, marked 
and annulated with yellow-brown and blackish, but not very uniformly. They are furnished with hairs. 
and a few fine spines. 
Palpi short, slender, yellow, the digital joint, and a spot at its base, blackish-brown, with a terminal, curved, 
apparently non-pectinated claw. 
Falces long, strong, yellow-brown, suffused in front, but not regularly or very distinctly, with a darker hue; at 
the extremity on the inner side near the base of the fang are two teeth. 
Mawille moderately long, much dilated at their extremity. Labium short, its height less than half of its 
transverse dimension, and its apex slightly roundly truncated. These parts are yellow-brown, indistinctly 
marked with a darker hue, and are almost at right angles to the sternum, which is large, somewhat sub- 
triangular or shield-shaped, of a pale yellowish colour marked with curved yellow-brown stripes, having 
three tolerably well-defined, large, oval, yellow, contiguous markings—one at its posterior extremity, the 
other two transversely towards the opposite end. 
The abdomen is large, (and when looked at in profile) higher than long; on the upperside are four strongish 
sib strongest and widest apart, the four forming very 
nearly a square. It is of a general whitish hue, mixed with indistinct blackish and brownish markings. 
The most distinct marking is a large somewhat cruciform white one in front of the two anterior promi- 
nences, the hinder point of the cross being dilated and truncate. The underside has a transverse black 
bar just in front of the spinners, and another across the middle, close behind the genital aperture, which
