fifth being longest : the double series includes four or five outer teeth and 
three inner ones, of which latter the first is far the largest and the third 
very small. 
Terminal fang moderate, curved outwards and gently downwards at 
the apex: on the inner edge superiorly is a short projecting keel 
immediately above the first tooth, only very slightly nearer to the anterior 
portion of the flagellum than to the tip of the fang. 
Lower jaw with two large curved teeth and two small ones between 
them, the more anterior of the two being very small : on the outer side of 
the jaw is a well defined lateral keel extending from the apex for a short 
distance along the jaw. 
Pedipalp. Metatarsus scopulate in its posterior half ventrally but 
the scopular area only extends over a distance about equal to one third 
the length of the segment. The short stout spines characteristic of the 
lower surface of the metatarsus occur also on the tarsus proximally and on 
the tibia distallv, but not on the femur. 
Posterior legs with only very few long hairs. 
Abdominal tergites quite devoid of fine hairs except on the last two 
segments. 
Colour. Headplate and abdominal tergites dull brownish, the 
appendages paler and more yellowish except the pedipalps which are 
brown and the distal half of the femur of the fourth leg which is also 
brown : lower surfaces yellowish : malleoli pale. 
Measurements. Total length 26 mm. ; length of tibia of pedipalp 8-5, 
of metatarsus and tarsus of pedipalp 7*5, of tibia of fourth leg 7*5, of 
metatarsus of fourth leg 6*75. 
This species is named after the eminent arachnologist Dr. W. F. 
Purcell, whose works on various families of South African Arachnida 
constitute our chief source of knowledge on the subject. 
It is referred to the genus Zeriassa Poc. solely on account of the 
spinulation of the pedipalp. 
Only one other species of this genus is known from Southern Africa, 
viz., Z. cuneicornis , Pure. ( Solpuga cuneicornis , Pure.) described from 
Southern Rhodesia (Annals S. A. Mus. 1, p. 413, fig. 20) : in both the 
flagellum and the dentition the two species are very distinct. The $ of 
cuneiformis is unknown. A fairly large $ sent to the Albany Museum 
along with the $ of purcelli is probably the $ of this species but without 
further evidence of its identity it cannot be described as such : the 
specimen seems to differ in no way from a $ Solpuga. 
Daesia rhodesiana , sp. nov. 
Type , a single specimen in the Transvaal Museum, collected near the 
Lundi River, S. E. Rhodesia, by Messrs. Noome and Roberts (24th August, 
1913). 
Colour. Headplate reddish brown, infuscated in places, paler over 
a narrow median area, mandible yellowish with two more or less distinct 
dark lines above. Abdominal tergu reddish brown throughout, except 
along the median line and at the sides where they are black : sides and 
lower surfaces pale. Palp brown, the metatarsus and tarsus brownish 
black. Fourth leg brownish, more deeply so on the distal portion of the 
femur. 
Pedipalp. Metatarsus in its distal half inferiorly with two rows of 
spines, three in each row : proximally there are several long spiniform 
setae on each side. Tibia inferiorly with an inner and outer row of three
