70 RECORDS OF THE AUSTRALIAN MUSEUM. 



few tiny setae ; pores numerous spread all over except on the 

 posterior third of the dorsal surface ; the pores are irregular in 

 size, a row of small pores is normally concealed under the lateral 

 margin of tlie sternum (Figs. 24 and 25). 



Anal pores present. 



Haase's description mentions that the claw of the maxillipedes, 

 when closed, hardly protrudes beyond the anterior margin of the 

 head, a character which might result from a stronger contraction 

 of the animal. His specimens are said to be furnished with a 

 small tooth inside the third joint of the maxillipedes (missing 

 in the Parramatta specimen), this however is a very unimportant 

 character. Also the last joint of the antenna?, according to the 

 German author, should bear a conical appendage, a fact which 

 could not be controlled here, the antenna? being abnormal. In 

 spite of these differences there seems to be no doubt that the two 

 forms are specifically identical.

 inner angle tipped with a conical process ; patella joint bearing

 smooth claw). 



Tergum of maxillipedes narrowed anteriorly ; internal margin 

 of pleurae- parallel ; (inner edge of the femoral joint unarmed).
