CHAMBERLIX: MYRIOPODA OF THE AUSTRALIAN REGION'. 87 



The collum of same general form as in C. kurandanum. Projecting anterior 

 median border bent more strongly ventrad; set off similarly by a fine trans- 

 verse sulcus. Coarse puncta in a series across anterior border and a few on 

 middle part of plate, the latter otherwise smooth and shining. 



Second tergite with margination as usual, the depression caudad of and 

 above it of usual general form but much shallower than in C. kurandanum and 

 scarcely present in the middle region. A vague transverse ridge a Uttle 

 behind caudal Umit of anterior third of length; surface smooth and shining, 

 weakly coriariously marked beliind the ridge, more roughened in front of it. 

 Other plates smooth and shining. 



Anal tergite also smooth and shining. Caudal margin very obtusely 

 shghtly angular at middle, the plate depressed above the angle. 



Tarsi with spine abo^'e claw as usual. 



Length (male), near 24 mm.; mdth, 11.8mm. Another specimen, an adult 

 male, is only 20 mm. long and 9.2 mm. wide. It is darker than the type. 



Clearly differentiated from other knowm species in the form of the 

 male gonopods. The posterior pair is characterized in having the 

 movable finger exceptionally large and heavy and somewhat clavately 

 widened abo\e the base, much exceeding the immovable finger; the 

 latter of a stout conical form, making a pronounced angle with the 

 axis of the basal part of the joint. The anterior gonopods greatly 

 smaller than the posterior pair; the immovable finger flattened, 

 apically rounded; the movable finger pointed distad, the tip curving 

 adaxialh- to or over apex of immo^'able finger.
