RUNCINIA.—SYNAMA. 79 
the joint in length, and ending with a very short curved claw or nail. The digital joint is of a narrow- 
oval form, sharp-pointed before. The palpal organs are simple, of a rather prominent semiglobular form, 
surrounded by a closely adhering black spine. 
The maxille and labiwm are similar to the cephalothorax in colour, the colour of the sternum being like that. 
of the two posterior pairs of legs. 
The abdomen is of an oval form, rather flattened; its colour is a dull brownish-yellow, the upperside smooth 
and glossy, showing distinctly the five normal impressed spots of a dark yellow-brown hue; the sides have 
a not very distinct blackish marginal stripe, and the underside has four longitudinal parallel blackish 
lines. 
In general appearance this species somewhat resembles Runcinia blanda, but the absence of the pairs of spines 
beneath the tibie and metatarsi of the first and second pairs of legs, and many other specific differences, 
will serve to distinguish it without difficulty.

TIBELLUS, Simon. 
Tibellus punctipes, sp. n. 
Adult female, length 3 lines, 
The cephalothorax, legs, palpi, and falces are pale yellow, marked with minute black spots, those on the legs 
being the largest. The abdomen is thickly mottled with white, powdered with very minute black points, 
and has an elongated cruciform dull blackish marking on the fore half of the upperside. The underside 
of the abdomen, as well as the maxille, labium, sternum, and coxal joints of the legs, is unspotted. 
The eyes are very small, black, and in the ordinary position, the height of the clypeus being half that of the 
facial space. 
The legs are moderately long, rather strong, furnished with hairs, bristles, and long spines.

SYNZEMA, Simon. 
Synema cirripes, sp. n. 
Adult male, length 2 lines ; length of leg of first pair 44 lines, and of leg of second pair 4 lines. 
The cephalothorax is nearly round. Caput short, slightly constricted laterally on the margins forwards, of a 
dull orange-yellow colour, narrowly edged with a black marginal line, and with the upper part of the 
caput in a large wedge-form, and some indistinct converging stripes on the sides, of a paler hue. The 
height of the clypeus is less than half that of the facial space. The fore margin and sides of the caput 
are furnished with some long, strong, spine-like, black bristles. 
The eyes are unequal in size, in form of a crescent, those of the lateral pairs the largest ; the largest of these 
being the fore laterals ; all are seated on bluish-grey tubercles, those of the laterals much the strongest. 
The four centrals are of equal size and form a square. The hind central pair are nearer to each other 
than each is to the hind lateral on its side, the fore central pair being much further from each other than 
each is from the fore lateral eye on its side. 
The legs of the first and second pairs are long, nearly equal in length (they were, in the only example examined, 
much damaged, but those of the second pair seemed to be longest),and rather slender ; the femora and genuze 
dark brownish-orange ; the tibie paler, with nearly the fore half deep reddish-brown. The metatarsi and 
tarsi are pale yellowish, the tip of the latter brown; they are armed with hairs, bristles, and slender spines. 
The hairs on the dark anterior portion of the tibiee of the first pair, and (in a less degree).on that of the 
second pair, form a kind of thin tuft. The spines of the first pair are stronger and more numerous than
