CHAMBERLIX: MYRIOPODA OF THE AUSTRALIAN REGION. 157 



of the keels in general similar; but an obvious difference in that the 

 excision opposite the angle of which the pore-cone stands is narrower 

 and more caudal in position, not at the corner, the caudal lateral lobe 

 thus extending farther caudad to the general line of the caudal margin 

 of the tergite instead of lying obviously in front of it as it does in T. 

 conformans; the cones are lower, rather thick, a little more remote 

 from the margin. 



Length, 4.6 mm.; width, .8 mm. 



EuPORODESMUS, gen. nov. 



Composed of head and twenty segments. Antennae moderately 

 long and slender, clavate; the articles much longer than thick, the 

 third and sixth longest, the fifth obviously shorter than the sixth; 

 fifth and sixth articles at distal end above with a small group of 

 sensory cones. First tergite completely covering the head from above. 

 The free anterolateral border wide, horizontal, divided by radial sulci 

 into twelve lobes but without corresponding emarginations, the mar- 

 gin being evenly continuous. Keels of other tergites widely horizon- 

 tally extended; the lateral and caudal borders divided into lobes by 

 radial sulci but the margins entire or with but slight emarginations. 

 Surface of tergites not truly tubercular or granular but diA'ided by 

 deep furrows into convexly rounded large areas of which there are three 

 transverse rows. Pores opening through short cones or subglobular 

 elevations situated on dorsal side of keel remote from the margin, 

 each occurring at the mesal end of the sulcus separating the caudo- 

 lateral lobe from the one just in front of it. Pores on segments five, 

 seven, nine, ten, twelve, thirteen, and fifteen to nineteen. Anal 

 tergite large, triangular, fully exposed from above.

Color of tergites dark brown, on the keels showing under the lens numerous 

 lighter areolations. Pleural region of both metazonites and prozonites also 

 dark brown. Venter fulvous. Legs brownish in a network of Unes over a 

 fulvous background, the trochanters contrasting by their paler color with the
