1 The numbers of dorsal teeth are given above and those of the ventral 

 below the horizontal line. In tlie case of the dorsal series, the full number is 

 shown to the right of the bracket, the plus signs indicating gaps between indivi- 

 dual teeth or series of teeth. The figure on the left, separated by the bracket, 

 represents the number of teeth situated on the carapace behind the orbital notch. 

 In the present species it will be noticed that these teeth invariably form a distinct 

 series, isolated by a toothless space from those further out on the limb of the 

 rostrum.
