216 Mr. E. J. Miers on Crustacea from 
Pilumnus verrucosipes. (Pl. XIII. fig. 5.) 
Pilumnus verrucosipes, Stimpson, Proc. Ac. Nat. Sci. Phil. p. 38 
(1858), 
Four specimens in the collection agree in all particulars 
with Simpson’s diagnosis, to which the following may be 
added :—'The front is rather prominent, its median notch very 
small; the first or exterior orbital tooth is small; the verru- 
cosities of the chelipedes and ambulatory legs are prominent 
and tuberculiform ; the outer surface of the larger chelipede 
(which may be either the right or the left) is nearly naked, 
and the granulations with which it is covered become obsolete 
toward the inferior margin. ‘The oblique ridges on the inner 
surface of the palate do not quite reach to the anterior margin 
of the buccal area. Orbital margin with a wide inner hiatus 
and a very narrow fissure near the outer orbital tooth, near 
to which, on the upper orbital margin, is sometimes a second 
very small tooth. Colour yellowish or olive-brown. Length 
of the largest example 3 lines (nearly 6 millim.), breadth a 
little over 4 lines (9 millim.). 
This species was hitherto unrepresented in the British- 
Museum collection; and its acquisition is of interest, since 
the type was obtained by the United-States expedition at 
Simon’s Bay, Cape of Good Hope. 
A Pilumnus (P. africanus) has been described by Prof. 
A. Milne-Edwards* trom Goree and Angola, which is in all 
respects very distinct from P. verrucosipes, and is allied in 
many of its characters to P. hirtellus. To it I refer speci- 
mens without locality in the Museum collection. 
with two obscure teeth on its inner surface; palm obscurely ridged and 
sulcated along the upper margin; fingers somewhat compressed, dis- 
tinctly toothed near the base, and ridged above ; pale coloured, the lower 
fingers only being excavated at tips; those of the larger chelipede widely 
gaping; ambulatory legs compressed. } : 
The specimen, which is preserved dry, has faint reddish markings on a 
ale ground. Length of carapace little more than 6 lines (11 millim.), 
Preaath about 8 lines (17 millim.). The smooth carapace, together with 
the obsolescence of the exterior orbital and first antero-lateral-marginal 
teeth, seems to distinguish this species, which was presented to the British 
Museum by the late R. MacAndrew, Esq. 
Tt bears a curious resemblance to Lophozozymus 6-dentatus, from which 
not only the excavated finger-tips but the much broader, smoother cara- 
pace, with less prominent front and smaller antero-lateral teeth, at once 
distinguish it. It is very nearly allied to Leptodius dispar, Stimpson, a 
Cuban species, in all particulars except that in L. dispar no trace exists 
of the third antero-lateral tooth, and the chelipedes are described as 
“naked, smooth, and polished; fingers a little more than one half as long 
as the palm, scarcely gaping, and but little excavated at the tips.”
