Perkera spinosissima . Saussure, Milne Edwards. 



The upper surface of the carapace has many spines ; 

 there are ten in a row in the middle line of the back, of 

 which four are on the gastric region, three on the anterior, 

 and three on the posterior cardiac lobes. The gastric 

 region has also on each side two very small points, behind 

 which there is one stronger. Two other spines occupy 

 the hepatic region ; there is a longitudinal series of three 

 small spines on the branchial region. The antero-lateral 

 edges have six strong points ; and there are small spines 

 on the posterolateral edges. 



The first pair of legs is short ; the arms have above 

 a line of five spines and some tubercles. The hand is 

 long and smooth ; the fourth joint of the walking legs 

 is tuberculous above. 



The colour under the hairs is red ; fingers brownish.

The carapace is wide in front, oval behind, and

 but there are no spines, with the exception of the 

 cardiac region, which has behind and in the middle 

 line a sharp spine with a smaller one in front of it. 

 The lateral border has four spines, one hepatic, three 

 branchial. Rostral horns of moderate size and very 

 diverging. Orbital edges large and armed with two 

 spines : the one, antero-superior, large and wide at its
