and other caudal appendages, all establish generic agreement 

 between Cratippus and Exunr/um, there are still some points 

 of difference available fur specific distinction, even allowing 

 for a reasonable ^irobability of error as to the finger of the 

 first giiathopods ot Crafij/pus (en tapes. For instance, the hand 

 is said to be three or four times as long as the wrist, whereas 

 in ( 'ratijtpus {Exuu(ju{o) stilijtrs the wrist is rather longer than 

 the hand ; the penultimate joint in the last three pairs of perei- 

 o])oda is described as serrated on the inner margin, while in 

 !Mr. Norman's species, or at any rate in my specimens of it, 

 that margin is perfectly even but for one very minute spine at 

 about the centre. The eyes are spoken of as round and black ; 

 but the colour of the eyes in a dead specimen cannot be de- 

 pended on.
