red bands on the upper surface of the arm ; and one of the 

 same colour on the distal surface of the hand.

? Myrodes eudactyla, Bell, 1. c, p. 299, pi. xxxii., fig. 6. 



Myrodes gigas, Haswell, 1. c, p. 52, pi. v., fig. 5. 



Myra eudactyla, A. M.-Edw., Nouv. Arch, du Mus., t. x., p. 46, 

 pi- iii., fig. 3. 



Carapace minutely and sparsely granulated, distinctly but 

 slightly carinated ; hepatic region with a small ridge, and a 

 marginal tooth ; cardiac region separated from the branchial on 

 each side by a slight depression, the posterior teeth rather small, 

 the middle one the longest and placed a little higher than the 

 others. Bostrum distinct, bifid, the two tooth-like projections 

 forming the covering of the antennary fossae, which are very 

 open. External foot- jaws with the palp evenly curved on the 

 outer edge. Anterior legs short, the arm minutely granulated ; 

 hand swollen at the base, narrowed forwards, as broad as it is 

 long ; the fingers slender, elegantly curved, longer than the hand, 

 armed with sharp teeth and hooked at the extremity, [i?.] 



The Australian specimens described by me as Myrodes gigas 

 belong without doubt to the New Caledonian species described 

 and figured by Dr. A. Milne-Edwards as Myra eudactyla, though 

 both differ considerably from Bell's figure. Bell's specimens 

 were obtained from the Philippines, and it is quite likely, 

 judging from the figure in Bell's Monograph, that the New 

 Caledonian and Australian species is distinct from it. 



Genus Philyba, Leach. 



Carapace orbicular, depressed, unarmed; front shorter than 

 the epistome. Antennulary fossse almost transverse. Orbit 

 open above, with three fissures. Palp of external maxillipedes 

 dilated. Eight posterior feet with a compressed tarsus. Abdo- 

 men of the male hastate lanceolate ; of the female with the last 

 joint narrow and much produced. [2?.]
