median article appears a little shorter than the visible part of the first, but, when measured 

 along the inner margin, the second article appears not shorter than the first. 



Telson 2,9-times as long as the width of the posterior margin, proportion between the 

 latter and the width at the base 2,14; the anterior pair of spinules of the upper surface, which 

 spinules are 0,22 mm. long, is just twice as far distant from the posterior margin as from the 

 base. In younger specimens the telson is longer with regard to the width of the posterior margin, 

 so in a very young specimen from Stat. 133, the carapace of which is 3 a / 4 mm. long, the 

 proportion is 3,2 and in the still younger specimen, examined by Coutière, the height of the 

 telson equals 3,5-times its posterior margin. 



In the specimen from Stat. 49 a the merus of the large cheliped is just twice as long 

 as wide. The proportions of the chela are: fingers i; total length 3,58; height 1,45; as is 

 prove'd by the numbers mentioned by Coutière, this chela appears in younger specimens longer 

 and higher with regard to the length of the fingers. 



In the young individual, examined by the french Carcinologist, the first carpal segment 

 of the second legs was just half as long as the sum of the four following and as the chela, 

 in the young specimen from Stat. 133 in which the carapace is j^mm. long, the sum of the 

 four last segments is 1,85-times, the chela, the fingers of which are one and a half as long 

 as the palm, 1,6-times longer than the first segment of the carpus; in larger specimens, as in 

 that from Stat. 49% the sum of the four last segments is one and a half as long as the first 

 and the chela, the fingers of which are longer with regard to the palm than in very young 

 individuals, only 1,36-times. In a young specimen from Stat 43, in which the carapace is 

 ; 2 s mm. long, the four last segments combined measure 2,15-times the length of the first, 

 but the chela only 1,85-times, the chela being a little more than twice as long as the fifth 

 segment. The second segment appears a little smaller than the third and than the fourth. In 

 very young individuals the merus of second legs appears 5-times as long as wide, in the specimen 

 from Stat. 49 a 4,3-times. 



The proportions of the third pair are in the specimen from Stat. 49 a : merus 2,8.; 

 carpus i; propodus 1,96. The merus is 3,73-times longer than wide and the propodus that 

 carries eight short spinules, long 0,1 mm., 4,7-times; the length of the dactylus, measured from 

 the proximal extremity of the anterior margin to the extremity of the ventral hook, is one-sixth 

 the length of the propodus. The dactylus is 2,2-times longer than wide and the two hooks 

 show the same thickness at their base. 



In a specimen long 10 mm. from Stat. 133 the proportions of the third pair are: 

 merus 2,82; carpus i; propodus 1,82; the merus is 3,64-times, the propodus 4,7-times longer 

 than wide and the dorsal hook of the dactylus appears a little thicker at its base than the 

 ventral. This is also the case in the young specimen from Stat. 43: whereas the posterior 

 margin of the clorsal hook is regularly concave, the anterior margin of the ventral runs like a S. 

 In this specimen the proportions of the third pair are: merus 2,375; carpus i; propodus 1,75; 

 the merus is 3,4-times, the propodus that bears 7 spinules, 4,37-times longer than wide and 

 the dactylus measures one-fifth the propodus. In the youngest specimen from Stat. 133, finally, 

 the carapace of which is 3,25111111. long, the proportions of the third pair are: merus 2,66;
