110 AUSTRALIAN LAND PLANARIANS^ 



Hah. — Bundanoon, N.S. W. ; under logs in a shady gully; a 

 somewhat scarce species. 



The strong contrasts of white, black, yellow and brown make 

 this little planarian very striking and handsome. 



Geoplana quinquelineata, var. accentuata, var.nov. 

 (Plate VII. figs. 6-7.) 



In their paper already mentioned, Messrs. Fletcher and Hamil- 

 ton describe G. quinquelineata from a series of specimens collected 

 in various parts of New South Wales, and at Sandhurst, Victoria. 

 From their description it is evident that the tj'pe of the species 

 has the median doi'sal line, if anything, rather less decided than 

 the lateral and marginal ones. In the note at the end of their 

 description, special mention is made of the Victorian specimens 

 and some of the New South Wales ones having the median line 

 more strongly coloured than the others, and it is indicated that 

 they expected at least varietal differences to be established when 

 larger suites of specimens came to be examined. 



I have been able to study a large series of specimens of this 

 species from the Blue Mountains and Bundanoon in New South 

 Wales, and from a considei^able number of localities in Victoria, 

 as well as from the Nerang River, Queensland. Without excep- 

 tion all my Queensland and Victorian specimens have the median 

 dorsal line much accentuated and darker in colour than the other 

 lines, while all my New South Wales ones have no such distinc- 

 tion, the median line being usually the least strongly marked of 

 all. A number of specimens from various parts of Victoria, 

 identified by Dr. Dendy as belonging to this species, and given 

 to me hj him, also agree in every way with my own specimens 

 from that colony. 



Mr. Fletcher has, with me, compared my specimens with those 

 collected by Mr. Hamilton and himself, and we are agreed that 

 the form having the dark median line should be considered as a 

 variety of G. quinquelineata, the form with the uniform slender 

 lines being regarded as the type of the species. 



The new variety is readily distinguished from the species by the 

 bold dark median line. After keeping in spirit for some time
