slightly ridged dorsal surface. In spirit a distinct, translucent, 

 median ventral band appears, as already noted in the original 

 specimen (this is much more obvious in some specimens than in 

 others). The peripharyngeal aperture (in spirit) is decidedly 

 behind the middle of the body, and the genital aperture much 

 nearer to it than to the posterior end. The pharynx is funnel, 

 shaped. The eyes appear to be be entirely absent. 



Diesing's Geobia subterranea, from Brazil, is described by 

 Moseley* as "Long and narrow, with rounded extremities, eye- 

 less, and colourless. Lives underground in the holes of 

 Lumbricus corethrunis, and preys upon that annelid." I have 

 Mr. Alexander Morton's authority for stating that Geoplana 

 typhlops is also sometimes found underground, but I believe that 

 this is true of many Land Planarians. Whether the genus 

 Geobia can be maintained appears to me very doubtful.

The known range of this common New South Wales and 

 Victorian species is now for the first time extended to South 

 Australia by the researches of Mr. Thos. Steel, from whom I 

 received two small specimens in spirit in May, 1892.
