pollex. There are no hairs or bristles in the palma. The legs of the 

 third, fourth, and fifth pairs present nothing unusual in structure, but 

 resemble the ambulatory legs common to 

 this family. In the sixth and seventh 

 pairs the structure is the .same as that of 

 the preceding legs of the third, fourth, 

 and fifth pairs, but with an increasing dis 

 proportion in the length of the propodus 

 and dactylus. In the seventh pair of 

 legs these joints, but more especially the 

 propodus, attain a size most conspicuous 

 for their length. The propodus becomes 

 over 3 2- times longer than the carpus 

 which immediately precedes it. 



Color. The color varies from dark brown 

 to yellow, more or less dotted with black. 

 In the darker specimens the epimera and 

 the uropods are almost white, with scat 

 tered spots of black. Other specimens 

 are brown with markings of red, and 

 some are bluish-gray in color tinged with 

 brown or orange. 



Type. The type specimen was found at 

 Station 3515, latitude 59 59' N., longitude
