3° the pectinated crest nearest to the base of the movable finger consists of 19 — 20, not 25, 



horny teeth. 

 4" the transverse crest on the inner surface of the palm is absent. 



The subspecies was obtained at Halmaheira, while the typical specimens came from Atjeh. 

 In acxreement with this distribution the two large cf from the Talaut Islands wholly answer 

 to the description of the Moluccan subspecies, but the young cf from Lombok belongs to the 

 typical form. 



On a oreenish or greyish-blue ground colour the adult animal is mottled by numerous 

 blotches and specks of a reddish-violet hue, especially the inner branchial regions. The chelae 

 are violet in their proximal part, but the distal part of the palm and the fingers are yellowish. 

 The numerous specimens from Nias, formerly examined by me, had the chelae always brightly 

 red, and the same has been stated by de Man about his Atjeh specimens.

This small specimen does not wholly agree with de Man's description, neither that of 

 1895, nor that of 1902, especially with regard to the chelipeds. Firstly there is a transverse 

 crest, consisting of 4 — 5 granules, on the inner surface of the palm, near the articulation of 

 the movable finger. Secondly the back of this finger presents a greater number(iS) of transverse 

 tubercles, whereas in typical specimens only 13 — 14 are observed, but in the figure of de Man 

 showing the chela in dorsal view 1 ) we may count as many as 16 tubercles. The pectinated 

 crests on the palm are shorter, the foremost of them consisting of 8 horny teeth, foliowed 

 by another row of only 5 — 6 teeth, but it is probable, that these teeth increase in number 

 with advancing age. 



The walking legs of my specimens are somewhat more slender than depicted by 

 de Man; the propodites of the penultimate pair are, according to the figure, only 2 a / 2 times 

 as lone as broad, but in the text it is stated, that they are more slender and this agrees 

 with my finds. Besides, these propodites appear to become more slender with advancing age, 

 for in larger specimens (length of carapace 13 — 10 mm.) they are four times (or nearly so) as 

 long as broad, but in smaller individuals (length of carapace 8.5 mm.) only three times 2 ). In 

 the "Siboga" specimen the length of carapace is 9.5 mm. and the said propodites are 3 1 /, 

 times as long as broad.
