I04 STALK-EYED CRUSTACEA 



and outside large and small tubercles. The superior 

 surface of the hand has two or three tubercles about its 

 middle. The teeth of its edges are larger and more 

 triangular than those on the borders of the arms ; those 

 on the internal border are larger than those on the 

 external border, especially towards the extremity of the 

 hand. The inferior surface of the hand is punctuated, 

 with a regular median row of tubercles. The walking 

 legs are a little compressed, the foUrth joint spiny above 

 and below. 



The ridges of the abdomen, sternum, and external 

 maxillipedes are tuberculated.

The carapace is wider than long, rounded, without 

 angles on the sides ; the regions are but slightly marked. 

 The surface is finely tubercular and granulated. The 

 largest tubercles are spiniform, and are arranged thus : — 

 Five upon the gastric region, of which four are placed 

 towards the middle, upon a transverse line, and another, 

 larger than the others, on the middle line behind these ; 

 three in a longitudinal row upon the cardiac region ; one 

 on each side of the urocardiac lobe ; five upon each 

 branchial region, and one upon the hepatic region. There 

 is a line of tubercles, forming a V, starting from the central 

 cardiac and each hepatic tubercle. The antero-lateral 

 border behind the hepatic region has six very small 

 teeth; below and behind the last there is a short and 

 dentiform ridge. 



The rostrum has two or three small teeth near the 

 basal teeth.
