Annals or the Tkansvaal Museum. 
Sternum about as long as broad and subcircular. Strongly fringed 
near its margin with spines, especially posteriorly, the spines anteriorly 
being longer, but more slender. The general surface is slightly curved 
and is beset with long slender scattered spines, which are longer than but 
not so stout as those on the ventral surface of the abdomen. Three pairs 
of sigilla, all marginal, the two anterior pairs situated outside the fringe, 
the third pair largest and forming a conspicuous depression. 
Labium broader than long, inclined obliquely downwards. It carries 
four broadly expanded denticles. 
Abdomen with truncated spines scattered about on all the surfaces : 
they are very strong anteriorly above, but comparatively weak over the 
greater portion of the mesial area dorsally. 
The lung-book stigmata are unusually small, being oval pores rather 
than transversely elongated slits. 
Anterior spinners comparatively slender and situated close together. 
Posterior spinners only a trifle more than \ the length of the sternum : 
basal joint longest, longer than the anterior spinners : terminal segment 
a little longer than the penultimate segment. 
Chelicerae with a single inner row of 7 or 8 teeth interiorly : outer row 
represented by 1 or 2 small teeth near the base of the series. A fringe of 
long hairs on the outer side of the fang groove. Rastellum absent. 
Scattered about, not very closely, on the anterior surface are a number of 
long stifhsh bristles, the stoutest of which are situated superiorly : several 
rather longer bristles occur on the anterior apical edge, but they do not form 
in any sense a definite row. 
Palp . — Tarsus with an internal row of 5 strong spines ventrally and 
an external row of 4 strong spines ventrally. Maxillae considerably longer 
than broad, with a basal patch of about 40 stout broadened denticles. 
Legs .- — Clothed with stiff setae and stout spines. Scopulae entirely 
wanting. Tarsi all without spines though short stiff setae are present. 
Median tarsal claw present, but rather small : paired tarsal claws with 
a double row of teeth, comprising 4 or 3 in each row and situated in the basal 
half of the claw. Metatarsus I with 4 strong spines anteroventrally and 
3 posteroventrally : II with 2 ventral rows of 3 each, also 2 on the anterior 
surface : III and IY with several spines on the posterior surface as well 
as ventrally and anteriorly, but there are none on the mesial portion of 
the dorsal surface. Tibia I with 3 spines at apex interiorly and 4 on the 
lower surface. Femora of palps and legs beset with a single row of strong 
truncated spines dorsally : on femur II the row is reduced to 2 distal spines, 
but on the other legs it comprises 4 or 5. On the patellae dorsally much 
shorter and weaker spines, also arranged in rows, occur, and rows of weak 
spines or stifhsh bristles occur on the dorsal surfaces of the tibiae and 
metatarsi. There are nowhere any dense groups of spines or spinules on 
the legs. Fourth leg longest : legs II and III subequal. Tarsi all shorter 
than the metatarsi. Metatarsus IY longest, about If times as long as. 
tarsus IY. Tibia I stouter than any of the other tibiae, a little longer 
than tibiae II and III, but shorter than tibia IY. 
Measurements . — Total length 9 mm., length of carapace 3, breadth 
of same 2 *5, length of first leg 9, of fourth leg 12.
