rosus, A. M.-Edw.; and the latter by MpixantTius Hellerii, a 

 species described also by Prof. A. Milne-Edwards. I may point 

 out that in JE. dentatus the inferior margin of the orbits presents 

 a distinct hiatus near the external orbital angle, whereas in 

 E. frontalis scarcely a trace of it is found. 



33. Epixanthtjs peontalis, H. M.-Edw. 



Ozius frontalis, Milne-Edwards, Hist. Nat. des Crustacis, t. i. p. 406. 



Epixanthus frontalis. Heller, Crustaceen der Novara-Reise, p. 20; Alph. 

 Milne-Edwards, I. c. p. 241. 



Nine specimens are in the collection, five (Id , 4t2) f fom 

 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 Eed Sea (Koss- 

 mann), in the Persian Grulf, Karak Island {Heller), at Zanzibar 

 (Hilgendorf), the coast of Tranquebar (Milne-Edioards), the 

 Nicobar Islands (Heller), the China seas, Japan (Stimpson), 

 and New Caledonia (A. Milne-Edwards) ; it would therefore 

 appear to be distributed throughout the whole lado-Pacific 

 Ocean. 



34. Epixanthus dentatfs. White. 



Panopseus dentatus. White, Proc. Zool. Sac. 1847, p. 226; Adams and 

 White, Zoology H.M.S. ' Samarang,' Crustacea, p. 41, pi. xi. fig. 1. 



Epixanthus dilatatus, de Man, Notes from the Ley den Museum, vol. i. 

 p. 58. 



Panopseus acutidens, Haswell, A Catalogue of the Australian Stalk- 

 and Sessile-eyed Crustacea, p. 51, pi. i. fig. 2. 



Epixanthus dentatus, Miers, On Malaysian Crustacea, Ann. and Mag. 

 Nat. Hist. 1880, 5th ser. vol. v. p. 233. 



Pour 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). 



Grenus Actumntjs, Eana. 



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).
