134 MR. E. J. MIERS ON CRUSTACEANS [Feb. 20, 
ETISUS DENTATUS. 
Cancer dentatus, Herbst, Naturg. Krabben u. Krebse, i. p. 186, 
pl. xi. fig. 66 (1790). 
Etisus dentatus, M.-Edw. Hist. Nat. Crust. i. p. 411 (1834). 
One specimen, a female with ova, is in the collection. This is 
another widely distributed species. Specimens are in the British- 
Museum collection from the Mauritius, Torres Straits, and New 
Caledonia. 
ACTHODES TOMENTOSUS. 
Zozymus tomentosus, M.-Edw. Hist. Nat. Crust. i. p. 385 (1834) ; 
Régne Animal de Cuvier, Atlas, pl. xi. dvs, fig. 2. 
Actaodes tomentosus, Dana, U.S. Expl. Exp. xiii. Crust. i. p. 197 
(1852). 
ee tomentosa, A. M.-Edw., Nouv, Archiv. Mus. Hist. Nat. i. 
p- 262 (1865). 
Four specimens of this species, all of them males and three of 
large size, were collected. Length of largest specimen ? inch, greatest 
breadth 11 inch. Like most of the species collected, this is a very 
common Indo-Pacific species. 
I may here observe that M. A. Milne-Edwards, in his revision of 
the Cancride (Nouv. Arch. Mus. Hist. Nat. i. p. 259, 1865), has 
united the genera Actea and Acte@odes, not considering the excavate 
or non-excavate finger-tips a character of genericimportance. Dana, 
on the other hand (Expl. Exp. Crust. i. p. 147, 1852), has based his 
subfamilies Xanthinze and Chlorodinee upon this very peculiarity of 
structure, and has shown that the genera may be arranged in each 
division in two parallel series. I am inclined to think the latter the 
most natural and convenient arrangement of the genera; but it will 
probably be necessary, if Dana’s system be adopted, to unite the sub- 
families Cancrinze and Xanthine, as the genus Cancer bears nearly 
the same relation to Héisus in the Chlorodine, as Liomera to Carpi- 
lodes, or Xantho to Leptodius. 
LEPTODIUS EXARATUS, var. SANGUINEUS, Milne-Edwards. 
? Chlorodius sanguineus, Milne-Edwards, Hist. Nat. Crust. i. p, 
402 (1834); Dana, U.S, Expl. Exp. xui. Crust. i. p. 207, pl. xi. 
fig. 11 (1852). 
Chlorodius nodosus, Randall, Journ. Ac. Nat. Sci. Phil. p. 111 
(1839); Dana, U.S. Expl. Exp. xiii. Crust. i. p. 210, pl. xi. fig. 14 
(1852). 
? Leptodius sanguineus, A. M.-Edw. Nouv. Archiv. Mus. Hist, 
Nat. ix. p. 224 (1873). 
Five males and one female specimen of a Leptodius were collected, 
which I should have referred, without any doubt, to the Chlorodius 
sanguineus of Milne-Edwards, were it not that M. Alphonse Milne- 
Edwards in his description says:—‘‘ Jamais il n’y a de tubercules 
sur les parties saillantes.” In the specimens before me there is a 
slight tubercle on the carapace behind each tooth of the antero-
