present 9 specimen has 4, the $ only 3, not counting the apical one. 

 This therefore is also a variable feature. 



The epistome has not yet been described by either author. In the

 width across the arms being about equal to the lateral margin, which 

 is slightly emarginate, the upper lip is not sunk in so far as to reach 

 the middle of the epistonie, the apex is bluntly rounded and the 

 surface granular and rugulose. 



Male stylet on pleopod 2 not developed. 



Both specimens were infested with lais pubescens (Dana).
