A Survey of the Scorpion Fauna of South Africa. 121 
PI. XX, flgs. 7 and 10, and Text-fig^. 2) seem to be fairly distinct. All our 
specimens from the Cape Province are referable to spenceri. 
It seems very probable that U. spinicaudus G-ervais (Arch. Mus. Paris, 
V, iv, p. 222, 1844) from Caffraria is the same els formosus, but as I have not 
yet seen specimens with precisely the same characters as depicted in G-ervais' • 
figures of the vesicle it seems permissible to ignore that species for the present ; 
Gervais' type was perhaps juvenile. 
U. FORMosus var. nov. maculipes. (Text-figs. 3 and 4). The type of 
this form is a single adult male from Invermanzi River, Zululand, now in 
the collection of the Durban Museum. It is a well marked form, perhaps 
worthy of specific rank. The tail is decidedly longer and more slender than 
that of formosus typicus ; only in the third segment is the end tooth enlarged 
and spiniform, being directed upwards and slightly curved forwards, that of 
the second segment being a very low tubercle, not better developed than the 
end tooth of the fourth segment ; the superior crests are not so sharply defined 
as in typicus, and the superior lateral crest of segment I, which is well 
developed in typicus, is feeble in maculipes ; the fifth caudal segment has 
the superior margin rather lightly curved and the upper surface is mesially 
channelled, but not so deeply nor so broadly so as in typicus ; the vesicle 
also is more elongated than in the male of typicus, the tubercle below the 
aculeus large and pointed ; granulation on the fifth caudal segment and 
vesicle almost obsolete. Tergites finely granulated throughout. On the 
movable finger the median series of granules includes 16 rows, the short 
apical row being counted in ; th6 3 basal rows are concentrated on the basal 
lobe ; the trio of granules is not well marked, as the penultimate granule of 
most of the median rows is not enlarged. The pigmentation is distinctive ; 
a thin median dark stripe along the first 6 tergites thus dividing the median 
flavous band ; on either side of the flavous band is a dark not very broad 
band with flavous markings, which are not distinctly > -shaped in each 
segment ; a fairly broad flavous marginal band ; last sternite quite pale and 
last tergite almost without infuscation ; fifth caudal segment and vesicle 
dark, the first four caudal segments pale, though some slight infuscation 
occurs on the fourth segment ; legs yellow with dark bands, humerus and 
brachium also banded, hand dark, fingers pale. 
Total length 35, length of tail 20-5, of first caudal segment 2-5, of second 
caudal segment 2*8, of third caudal segment 2*9, of fourth caudal segment 
3*6, of fifth caudal segment 4*1, of vesicle 4*2, height of fifth caudal segment 
2-2, length of hand 6*75, of movable finger 4-1, of brachium 3*7.

Distribution : Only known from the immediate neighbourhood of- Cape 
Town, being recorded by Dr. Purcell (17) from the I^ewlands and Constantia 
slopes of Table Mountain and from Kalk Bay Mountain.
