where it bifurcates and is continued on the second. The two 

 lateral red bands commence at the external orbital angles, and by 

 slight curves extend to the commencement of the postero-lateral 

 borders ; the external white lines are confined to the antero-lateral 

 lobes ; the inner pair of white lines commences at the orbital 

 borders and is continued to the posterior margin of the carapace. 

 The cardiac region appears to the unaided eye as if it had a 

 median groove, but on closer inspection with a lens it is seen that 

 this appearance is due to the deeper shade of red rather than 

 to a depression. 



The hairs on the carapace are yellowish, the longer ones form- 

 ing fringes around the bases of the lobules, and the shorter ones 

 at the bases of the granules. 



Length of carapace 8mm. 



Breadth of carapace 10mm.

There are five examples of this species three males and two 

 females : the post abdomen in the latter is fringed with long hairs.

A solitary female of this rare and beautiful species was 

 collected. 



It presents several important characters not mentioned in the 

 original description by Dana. The carapace is smooth, shining, 

 and minutely punctate ; when viewed with a lens it is seen to be 

 covered with a uniform but microscopic granulation. On the 

 chelipedes and ambulatory legs the granules tend to become seriate 

 and form reticulating lines with smooth spaces between. 



On the sub-hepatic and pterygostomial regions the granules are 

 larger and visible to the unaided eye, more especially along the 

 line defining the regions, and extending from below the basal 

 joint of the external antennae to below the second antero-lateral 

 spine. 



The chelipedes are equal ; the ischium is hairy and granulose, 

 on its anterior edge, at its distal extremity, is a low tooth bounded 

 by a transverse groove. 



The external surface of the merus is smooth and convex ; the 

 anterior granular ; the internal concave, adapted to the shape of
