This is a very distil ( genus, the characters of which air constant in all the 

 species. The mandibular tooth is -mall, ami often entirely absent Tin 

 spiratory organs are not closed by valves, tun are funned, externally, each bj 

 a large auboval, cribriform plate (Tab. XL. placed verticalli at 



the sides of the second, fourth, sixth, seventh, ninth, and sue© alternate 



segments. The perforations in these plates communicate Internally with a 

 large number of minute tracheal vessels, one to each perforation, and do not 

 together open at once into a large tracheal stem, like the valvular spiracles ,,, 

 other Scolopendrtdee. This peculiarity of structure of the breathing orgat 

 associated with a very marked form of head, large elongated antennae, tt< 

 and powerful labial teeth, and strong posterior 1< --. of which the femora 

 have large acute spines. These characters seem to indicate very preda< . 

 habits. 



Most of the species hitherto obtained are from the western coast ol 

 and from Australia, and there is also one of the most marked species of the 

 genus from Ceylon, and one from the South Sea Islands. 



This genus includes the majority of the species described as Longidentaia f 

 in my former account of specimens in the collection at the British Museum.
