raerus one and a quarter times the lengtli of these joints. Carpus 

 and meriis each with a bhint tooth on tlie lower inargins. The 

 liands, too, ai-e generally similar, l)ut that of the smaller chelipede 

 is more narrowed distalW, owing to the greater obliquity of its 

 lower margin ; the fingers of both are short, but the dactyl of the 

 larger hand is more curved than that of the smaller ; a few scattered 

 longish hairs are found on the fingers of both hands. The outer 

 and inner sui'faces of both carpi and propodi have a brownish-red 

 basis of colouring (in formol) with white blotches or spots, the 

 white parts appearing under a lens rather as an incrustation on 

 the general surface.

A female with ova; length 24 mm. A note in the bottle with

Loc. Singora, twelve males, ranging from 150 mm. in length. 

 Kelantan, two males, length 90 mm. and 73 mm. Tale Sap, a male, 

 length 104-5 mm. 



P. carcinus, var. lamarrei. Loc. ? — A male of 43 mm. in length, 

 in which it is noticeable that the inner lateral spines of the telson 

 are longer than the tip of the telson itself. The tip is rounded, 

 and probably broken short at some period, but in any case the 

 lateral spines would be the same length as the tip. Carpus of 2nd 

 pair as long as hand ; surface of 2nd pair smooth, punctate, with 

 short hair at intervals.

 fig. 36 (1892). 



Loc. Kelantan, two males; length 100 mm. and 78*5 mm. 



The larger male exhibits what is possibly a deformity of the 

 fingers of the 2nd pair. The index of the right hand is broken off 

 near the tip, but shows the regular light concavity of the lower 

 border ; that of the left hand, however, is only two-thirds the 

 length of the dactyl and ismoderatelyconv^o? along its lower border.
