the front, and a less clear row of beads along the upper margin of the orbit ; 
along the lobes of the antero-lateral borders of the carapace they tend to be 
dentiform in the two smaller specimens and absent in the larger one; on 
the rugule of the upper part of the outer surface of the hand they are also 
clearly seen, but they are very obscure on the inner surface of the palm; on 
the upper margin of the meropodites, carpopodites, and propodites of the 
walking-legs they are crisp, two rows on the upper border of the dactylo- 
podites being more or less spiniform ; there are a few minute spinules on 
the lower margin of the propodites and dactylopodites ; on the lower margin 
of the dactylopodites, at the base of the terminal light brown horny claw 
and at right angles to it, is a strongly developed tooth, about a quarter to a 
third as large as the claw itself. The dactylopodites have thus for X. hydro- 
philus a well-armed aspect (PI. 43. fig. 1). The antero-lateral teeth of the 
carapace are well developed and procurved. 
Stimpson gives an interesting list of varieties of this highly variable species, 
but the present specimens do not fall under any variety described by him. 
They have somewhat the granulation of his var. 7, granulosus (loc. cit. p. 56, 
pl. 6. fig. 3), though the spiniform tendency of the granulation of the dacty- 
lopodites of the walking-legs is not mentioned by Stimpson, while the 
granules of the outer surface of its hand appear in his variety to be larger and 
more conspicuous than in my specimens. The antero-lateral teeth have much 
the appearance that they have in Stimpson’s figure of his var. h, latus (loc. 
cit. pl. 6. fig. 9), 7. e. less triangular than in granulosus, and the last two in 
particular are more tooth-like in form, but their margins do not bear large 
granules. 
The denticulate armature of the walking-legs, and of the dactylopodites in 
particular, is noteworty; this and the general tendency to granulation all 
over the animal are differences from Alcock’s description.

It will be noticed that the chelipeds of the g have by no means yet

is ovigerous. 
In the 2 specimen the right, and in the ¢ the left, chela is the more
