280 On Crustacea from Goree Island, Senegambia. 
pendage of the left fifth leg is articulated with the posterior 
surface of the basal joint and is membranaceous, with the 
outer margin indurated and diminishing in thickness to the 
extremity, which is slightly hairy. The uropoda are unequally 
developed, the rami of the right being smaller than those of 
the left. Colour (in spirit) whitish. Length of the cephalo- 
thorax of the male a little over 6 lines (13 millim.), of right 
chelipede about 9 lines (19 millim.). The full extension of 
this limb, however, is not possible. 
The single example (male) is in imperfect condition, not 
only the fourth pair of legs but also the second leg on the 
right side being deficient. 
In 8. spiriger (De Haan), from Japan, the ciliated 
striations of the limbs exist, it would appear, on the cheli- 
pedes as well as the followmg limbs. In S. dispar, Stimpson, 
from Barbadoes, the fingers of the right chelipede are short, 
not more than half the length of the palm, and are coarsely 
toothed within. 
In S. cris, A. M.-Edwards*, also from the Barbadoes, 
there is a distinct rounded rostriform lobe, and the chelipedes 
are covered with small spines.

Several small specimens, representing both sexes, are in 
the collection, which I refer here with little hesitation. The 
scarcely differ from the much larger specimens in the collec- 
tion of the British Museum, except in the lesser granulation 
of the chelipedes, which yet are of the form so characteristic 
of H. excavatus. ‘The spinules arming the upper margin of 
the penultimate and antepenultimate joints of the right 
leg of the second pair exist, but are with difficulty dis- 
cernible among the hairs with which this limb is clothed. 
Colour (in spirit) light yellowish; limbs pinker. The length
