732 NOTES ON SOME LAND PLANARIANS, 



which is convex ventrall}^ in spirit and usually broader behind 

 than in front, and in the characteristic posterior position of the 

 genital aperture, this variet}" agrees closely with the typical form 

 of the species. 



The species has not hitherto been recorded from New South 

 Wales.

A considerable number of specimens of this species were sent 

 to me from Blackheath. They differ from the type of the species 

 as originally figured in the more speckled character of the dorsal 

 and lateral surfaces, the greater breadth of the median dorsal 

 black stripe, and the concentration of the speckles towards the 

 margins of the dorsal surface to form a pair of more or less well- 

 defined, narrow dark stripes. The dorsal surface in spirit speci- 

 mens is also more convex than in the typical form, and the section 

 therefore less markedly quadrangular. They closely resemble 

 my G. quadrangulata var. tvellingtoni, from Mount Wellington,. 

 Gippsland, Victoria, but attain a much larger size, one specimen 

 being 46 mm. long when crawling. They also form an interesting 

 connecting link between the typical G. quadrangnlata and the 

 common New Zealand species which I have named suhquadrangu- 

 lata, and which is distinguished chiefly by the much stronger 

 development of the paired stripes, far surpassing that of the 

 median one. 



As suggested to me by Mr. 8teel, the specimens collected by 

 him also make a near ajjproach to Messrs. Fletcher and Hamilton's 

 description of their Geoplana ornata, but they certainly differ 

 much in appearance from their figure.
