from 2 to 4 tubercles along a similar region. These characters 

 do not appear in young males, "males feminises," nor females. 

 The keel of the cutting edge of both fingers in young males and 

 all females is well developed but low. It decreases in height 

 as the body length increases, so that in the oldest males it is only 

 a raised line. In the youngest males and females (Nos. 1 and 

 15) no teeth can be seen on the fingers, but slightly older speci- 

 mens (Nos. 2 and 16) show 2 teeth on the mobile and 1 tooth 

 on the immobile finger. The condition last mentioned is char- 

 acteristic of all the females of this species in our collection, ex- 

 cept of No. 15, but an examination of the older males shows the 

 presence of confluent teeth back of the tooth, mentioned above, 

 on the immobile finger. These teeth make their first appearance 

 in No. 3, being represented by 1 or 2 very small teeth, but 

 with increasing body length the number increases to 3 or 4. 



The palm is cylindrical in cross section, that of one of the 

 large males (No. 12) measuring 4 millimeters and that of a 

 small male (No. 3) measuring almost 2 millimeters in diameter 

 at the middle point. 



The carpus is also cylindrical in cross section, and in females, 

 young males, and "males feminises" it increases in diameter 

 passing from the distal to the proximal end. The same is true 

 for young mature and old mature males, except that the greatest 

 diameter is reached some distance posterior to the distal end. 

 The carpus is shorter than the propodus and longer than the 

 palm or the fingers; the palm, however, grows faster than the 

 carpus. 



The proportion of the merus to the carpus ranges from 1 : 1.33 

 in the smallest male to 1 : 1.64 in the largest, showing that the 

 carpus increases in length faster than the merus. The latter is 

 longer than the palm and is of the same length as the fingers in 

 the smallest male and shorter than the palm and longer than the 

 fingers in the largest. The merus, as in other species, is flattened 

 dorsoventrally along the proximal part, becoming almost cylin- 

 drical and of greater diameter in the distal region. 



Third, fourth, and fifth legs. — In the smallest male, the dactyli 

 of the third and fourth legs and the tip of the propodus of the 

 fifth leg extend beyond the antennal scale. The propodus of 

 the fifth leg measures 5.5 millimeters in length and 0.1 milli- 

 meter in diameter at the middle region. One of the oldest males 

 (No. 12) shows one-third of the propodus of the third and fourth 

 legs beyond the tip of the antennal scale, while in the fifth leg 

 one-fourth of the propodus is seen beyond. The propodus of
