^specimen when crawling about 40 mm., breadth 1 to Ij mm. 

 Ventral surface uniform light ashy grey. Dorsal surface uniform 

 l^lack. No stripes on either surface. Eyes two, usual position, 

 conspicuous. 8ame specimen in spirit, length 38 mm., breadth 

 •3 mm." To this I may add that in spirit the peripharyngeal 

 aperture in one specimen is situate near the hinder end of the 

 middle third, and the genital aperture rather nearer to the 

 posterior end than to the peripharyngeal. Another specimen in 

 spirit shows a distinct median longitudinal stripe of darker tint 

 ■on the dorsal surface. 



Obviously the specimens approach more nearly Messrs. Fletcher 

 und Hamilton's R. obscicrus than to their R. moselei/i, but I am 

 forced to the conclusion that the distinction between most of the 

 described Australian species of Rhynchodemus is too slight to be 

 maintained, and that the first name, R. moseleyi, will prol^ably 

 have to cover at any rate R. obscurus, R. Irilineatus and R. niger 

 ■of Messrs. Fletcher and Hamilton, and perhaps also my own 

 Victorian R. siniulans. 



The localities of Mr. Steel's specimens are Blackheath and 

 AVentworth Falls.

AVhen crawling about 35 mm. long and 1-5 mm. broad. Eyes 

 two as usual, very near the anterior end, in the broad bands of 

 dark ground colour and therefoi-e difficult to distinguish. 



Ground colour of dorsal surface ashy black, with three pairs of 

 very narrow stripes of pinkish white, arranged as follows : — One 

 pair encloses a narrow median fcand of ground colour of about the 

 same width as themselves. Outside these on each side comes a 

 Ijroad band of ground colour extending nearly to the margin; 

 then another narrow stripe oi pinkish white like the preceding; 

 then a band of ground colour about twice as broad as the white 

 stripe; then another narrow pinkish white stripe as before, and 

 then, on the margin, a narrow band of dark ground colour not
