cylindrical, slightly longer and much thicker than neck. Palpi with 

 scape longer than second segment, slightly curved, almost as long as 

 proboscis; second segment shorter and heavier than scape; both 

 movable and immovable fingers long and slender and v^ell-toothed 

 on their inner margins. Immovable finger almost straight to distal 

 part, which terminates in a curved tip; movable finger curved and 

 longer than immovable; both fingers armed on their inner margin 

 with teeth, some of which are almost contiguous at their bases, and 

 all are pointed almost evenly to their apexes and somewhat curved. 



Ovigera 10-segmented ; first segment very short; second and third 

 about equal and a little longer than the first; fourth about twice as 

 long as first three together; fifth slenderer and longer than fourth, 

 swollen at its distal end (it is this segment around which the eggs 

 are carried in one or two closely packed masses) ; sixth segment 

 much shorter and armed with many short hairs on its ventral side; 

 seventh shorter than sixth and closely beset on its ventral margin 

 with an even row of about 13 elongated spines, which are armed 

 laterally, these spines almost touching one another at their bases and 

 about as long as the segment is thick; eighth a little shorter than 

 seventh and armed as seventh ; ninth and tenth about equal to seventh 

 in length and similarly armed; these last three segments are defi- 

 nitely curved on their ventral margins and form a curved end to 

 tlie oviger as a whole ; the tenth segment bears a long well-developed 

 claw, which is armed with ordinary teeth on its ventral margin, as 

 are the fingers of the chelae.
