238 CARCINOLOGICAL STUDIES. 



verse , minutely granulated lines are observed on their 

 outer surface. The upper surface of the wrist is a little 

 rugose towards the external and internal margins; the 

 internal margin is armed with a strong acute tooth , be- 

 low which there is a much smaller one. The larger hand 

 (fig. 2d) closely resembles that of Telphusa obesa A. M. E., 

 a species which inhabits Zanzibar and the opposite coast 

 of Africa (Nouv. Archives du Muséum , tome IV, pi. 20 , 

 fig. 3). The outer surface of the palm appears minutely 

 punctate, but for the rest quite smooth and shining to 

 the naked eye; under a strong magnifying-glass an ex- 

 tremely fine and minute granulation is however observed , 

 with which the palm is covered. The palm is almost as 

 long as high at the base of the fingers; its upper margin 

 is rounded and the under margin also rounded and con- 

 vex. The fingers, that , measured horizontally , appear 

 nearly once and a half as long as the palm, are widely 

 gaping, almost as much as those of the larger hand of 

 Telphusa obesa. Like the palm , they are minutely punctate , 

 and being smooth to the naked eye, they in fact seem 

 to be minutely granular, when examined under a strong 

 magnifying-glass. The index, forming a concave line with 

 the lower margin of the palm , presents a strong tooth at 

 a short distance from its base, preceded by three very 

 small ones ; a smaller tooth stands on the middle of the 

 finger and between this tooth and the tip still nine or 

 ten very small teeth are observed. The strongly arcuate 

 mobile finger is armed with a strong tooth a little before 

 the middle, standing somewhat beyond the principal tooth 

 of the index; a much smaller tooth is seen near the base, 

 and between the tip of the finger and the strong tooth 

 in the middle, still eleven or twelve very small teeth are 

 observed. 



The fingers of the smaller hand (fig. 2e), when closed, 

 meet together along their whole length; they are also 

 nearly once and a half as long as the palm. Both fingers 

 are feebly toothed ; on the lower about twenty small teeth
