also a little longer in proportion to the shorter palm. In 

 another , on the contrary , the fingers are a little higher 

 in proportion to their length as ordinarily and the lobe 

 of the index is rounded and but little prominent. These are , 

 however , individual variations. 



I must finally remark that the coloration of these spe- 

 cimens difiers also a little from the type, as the arm, 

 the carpus and the palm of the larger hand 

 are of a pale greenish or bluish gray colour, 

 instead of presenting the yellowish red observed in the type.

Two male specimens belong to that variety , in which 

 the larger hand is more slender and more elongate. In a 

 typical specimen from the Mergui Archipelago the larger 

 hand has a length of 22^4 mm. and a height of 8'/4 mm. 

 In the two specimens from Upolu these numbers are 24^/3 

 mm. and 7\/4 mm. for the larger, 23 mm. and 7V4 mm. 

 for the smaller specimen. This variety occurs also in Amboina.
