 This is the type of the genus.

It seems impossible to identify this species or to determine its 

 generic position from Button's meagre account; and as serratus is 

 preoccupied, to do so is unnecessary.

Probably not to be recognized without examination of the type. 

 Hutton states that the segments are " eighteen or nineteen, the same 

 as in the last." 



Tasmanodesmus, gen. nov. 



Composed of head and twenty segments. Antennae long and 

 slender, distally clavate; second and third articles longest, the fourth, 

 fifth, and sixth subequal. First tergite of ordinary size and form; 

 nearly equal in width to the second. Tergites without sulci or these 

 but obscurely indicated; wholly lacking tubercles or granulations, 

 smooth; each with three transverse series of setae, the caudal one 

 marginal, the others submedian and postmedian respectively, their 

 setae arising from depressions or foveolae. Keels broad, horizontal, 

 the posterior corners angular, in most, especially the more caudal ones, 

 strongly produced; dorsal surface smooth; caudal margin smooth; 

 lateral margin smooth or weakly serrate. Pores dorsal in position, 

 located near beginning of posterior third of length; on fifth, seventh, 

 ninth, tenth, twelfth, thirteenth, and fifteenth to nineteenth somites.
