46 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
rosus, A. M.-Edw.; and the latter by Epicanthus Hellerii, a 
species described also by Prof. A. Milne-Edwards. I may point 
out that in #. dentatus the inferior margin of the orbits presents 
a distinct hiatus near the external orbital angle, whereas .in 
LE. frontalis scarcely a trace of it is found. 
33. Eprxantuus FronTALIS, H. I -Edw. 
Ozius frontalis, Milne-Edwards, Hist. Nat. des Crustacés, t. i. p. 406. 
Epixanthus frontalis, Heller, Crustaceen der Novara- Reise, p. 20; Alph. 
Milne-Edwards, 1. c. p. 241. 
Nine specimens are in the collection, five (1¢, 492) from 
King Island, three from Sullivan Island, and one from Elphin- 
stone Bay. In all the right hand is the largest. 
Epixanthus frontalis has been observed in the Red Sea (Koss- 
mann), in the Persian Gulf, Karak Island (Heller), at Zanzibar 
(Hilgendorf), the coast of Tranquebar (IMilne-Edwards), the 
Nicobar Islands (feller), the China seas, Japan (Stimpson), 
and New Caledonia (A. Milne-Hdwards); it would therefore 
appear to be distributed throughout the whole Indo-Pacific 
Ocean. 
34. EPIXANTHUS DENTATUS, White. 
Panopeus dentatus, White, Proc. Zool. Soc. 1847, p. 226; Adams and 
White, Zoology H.M.S. ‘ Samarang,’ Crustacea, p. 41, pl. xi. fig. 1. 
Epixanthus dilatatus, de Man, Notes from the Leyden Museum, vol. 1. 
p. 08. 
Panopzus acutidens, Haswell, A Catalogue of the Austrahan Stalk- 
and Sessile-eyed Crustacea, p. 51, pl. i. fig. 2. 
Epixanthus dentatus, Miers, On Malaysian Crustacea, Ann. and Mag. 
Nat. Hist. 1880, 5th ser. vol. v. p. 233. 
Four specimens were collected at Elphinstone Island. There 
can be little doubt that Haswell’s P. acutidens is identical with 
the species described by White. 
Epixanthus dentatus has been collected on the coast of Java, 
at the Philippine Islands, and on the coast of Australia (Port 
Darwin). 
Genus Actumnus, Dana. 
This genus is described as having the fingers of the chelipedes 
spoon-shaped. In the species represented in this Collection 
the fingers have pointed tips—a fact already pointed out by 
Prof. A. Milne-Edwards in the case of one of them (Nouv. 
Arch. t. ix. p. 194).
