130. Actumnus nudus, A. M. Edw. 



Actumnus nudus, A. Milne Edwards, Ann. Soc. Entomol. France, (4) VII. 1867 

 p. 265 : de Man, Journ. Linn. Soc, Zool., XXII. 1887-88, p. 49, pi. ii. figs. 3, 4. 



Carapace almost completely bare, legs with only a few scattered 

 hairs. 



Carapace subcircular, convex, regions hardly indicated, studded 

 with pearl -shaped granules in its anterior and antero-lateral parts, 

 twelve of these granules are arranged in an arched line — convex for- 

 wards — on either side of the posterior end of the gastric region. 



Front much advanced, divided into two rounded oblique lobes, the 

 outer angles of which are hardly separated from the supra-orbital 

 angles. 



Antero-lateral border divided into four teeth (not including the 

 outer orbital angle). 



Chelipeds unequal ; upper and outer surfaces of hand covered with 

 pearly granules, which also exist on the upper surface of the wrist. 



Found at Pondicherry and Mergui. 



Not represented in the Indian Museum collection. 



This species seems to me to be improperly referred to Actumnus.

Heteropanope, de Man, Journ. Linn. Soc, Zool., XXII. 1887-88, p. 52. 



Carapace moderately broad, moderately or little convex, with the 

 regions little or hardly demarcated. 



Antero-lateral borders shorter than the postero-lateral, cut into 

 four lobes or teeth, of which the first is confluent with the outer angle 

 of the orbit : postero-lateral borders moderately convergent, posterior 

 border rather long. 



Front moderately broad, between a fourth and a third the greatest 

 breadth of the carapace, cut into two lobes, the outer angle of each of 

 which is dentiform and separated from the supra-orbital margin by a 

 notch. 



A small triangular gap in the orbital margin just beneath the 

 outer angle. The antennules fold nearly transversely.
