bles the adult g@ in color characters, except that the yellow 
patches on the side of the head are reduced to marginal bands and 
the fourth and fifth and eighth and ninth terga are only pale pos- 
teriorly. Until evidence to the contrary is forthcoming, it may be 
assumed that this specimen is the 2 of A. smzthiz.

‘Egyptische und Abyssinische Arachniden, p. 1, Pl. I., fig. 1, Nurnberg, 1875. 
Scorpio bellicosus, 1. KOCH. 
Three female examples, referred with some hesitation to this 
species, were collected, of which unfortunately only one, the 
smallest, is labelled with an exact locality. This was obtained 
near Aimola in the Boran country, 3,000 ft. 23.3.95. Fortunately 
this example has the carapace of almost exactly the same length 
as the female example of Sc. cavimanus, Poc., from Ugogo, 
mentioned in Ann. Mag. Nat. Hist. (6), xvi. p. 4313 and since 
it is largely upon the differences in measurements presented by 
these two specimens that the examples obtained by Dr. Smith are 
referred to de//tcosus rather than to cavzmanus, I give here their 
measurements in millimetres : — 
2 of cavimanus from Ugogo. Total length, 92; length of 
carapace, 16; of tail, 46; of caudal segment, 1 and 2,12; of 4 and 
5, 17.3; length of hand-back, 8.5; width of hand, 14; length of 
immovable digit along its free (untoothed) edge, 7.5; width of 
the same at the base, 5. 
2 of bellicosus from the Boran couutry. Total length, 82; length 
of carapace, 15.5; of tail, 37; of its 1st and 2d segments, 10; of 4 
and 5,13; length of hand-back, 7.6; width of hand, 11; length 
of immovable digit along its free edge, 8.5; width of latter at 
base, 3.8. 
These data show (1) that the tail as compared with the carapace 
is much shorter in de//cosus than in cavimanis, the carapace in 
the former being shorter than the 4th and 5th caudal segments, 
whereas in the Jatter it is longer; and (2) that the immovable digit 
In cavimanus is much wider at the base as compared to its width 
than in de/licosus. Corresponding features are presented by the 
two larger specimens, which are about 113 mm. in length, with the
