161. Actumnus bonnieri Nobili. 



Actumnus bonnieri Nobili, Bull. Sci. France et Belg., xl. 1906, p. 132, pi. 6, 

 fig. 32. 



Seychelles, 31 fms., Sta. F 2; 1 ? juv. C. b. 4"2 mm. 



The lobules of the carapace are high and deeply separated from one another. The 

 outline of the lateral teeth is not obscured by tomentum ; the teeth are denticulated. 

 The marginal projections of wrist, palm and movable finger are so sharp as to resemble 

 spines. 



162. Actumnus globulus Heller. 



Actumnus globulus A. Milne Edwards, Nouv. Arch. Mus. Hist. Nat., Paris, i. 1866, 

 p. 286, pi. 18, fig. 4. 



Salomon; 1 ?. C. 1. 9 mm., C. b. 12 mm. 



The antero-lateral margin is cut by three closed fissures, each lobe thus formed 

 overlapping the one anterior to it. The two frontal lobes are oblique and are separated 

 from the orbital angles by a well-marked sinus. 



163. Actumnus obesus Dana. 



Actumnus obesus Rathbun, 1906, p. 865, pi. 11, fig. 2. 



Amirante, 29 fms., Sta. E 2 ; 1 ? : 20—25 fms., Sta. E 13 ; 1 $ ; C. 1. 77 mm., C. b. 

 10-1 mm. : 30 fms., Sta. E 21 ; 2 ?. 



In the specimen measured, the lateral teeth are better marked than in the larger 

 specimen from the Hawaiian Islands described in the report cited above. In the females, 

 which are all small, about 6*6 mm. wide, the tomentum almost conceals the regional 

 divisions of the carapace. 



164. Actumnus simplex, sp. nov. (Plate 16, figs. 10, 11). 

 Amirante, 32 fms., Sta. E 12 ; 1 ?. 



Ovigerous female, C. 1. 8*6 mm., C. b. 11 mm. 



Carapace covered with a very short, scant pubescence, not visible to the naked eye ; 

 a transverse line of long hairs behind the front ; chelipeds and legs furnished with long, 

 ragged hairs which, on the arms, wrists and legs, are confined chiefly to the margins, 

 but cover the whole outer surface of the palms. Carapace very convex in both directions. 

 The only separation into regions is indicated by shallow branchio-cardiac furrows. Front 

 narrow, a median emargination, lobes oblique, their outer angles connected by a straight 

 line with the orbital angles. Two superior orbital fissures faintly indicated ; external 

 fissure V-shaped. Antero-lateral margin cut by three shallow notches into lobes, the 

 posterior of which is bluntly dentiform. From it a low, finely granulate ridge runs inward 

 on the carapace.
