7. Geoplana quinquelineata, n. sp. 



(Plate V, figs. 4, 5, 15, 16). 



Undersurface whitish. Ground colour above presents consi- 

 derable variations, pale yellow or nearly orange, dull olive-green, 

 ochreous-brown, reddish-brown, sometimes almost brick-red. The 

 dorsal surface divided into six longitudinal bands by five longi- 

 tudinal lines, also varying in colour, sometimes a darker and more 

 intense tint of the ground colour, from dark brown almost black 

 to warm brown or red, their margins irregular when viewed with 

 a len,s, arranged as follows : usually a very fine daik line occupies the 

 median line, external to which on each side is anarrowband of ground 

 colour; outside of which again on either side is a line of brown 

 or red usually slightly broader and better defined than the mesial 

 line ; each of these again is bordered by a band of ground colour one 

 and a-half times or twice as wide as the inner stripe on each side ; 

 beyond each of which is the outermost brown or red line of the same 

 width as the first on each side but sometimes narrower, and each 

 of these is followed by a narrow band of ground colour extending 

 outwards to the lateral margin of the body. At the anterior 

 extremity the lines blend in the red tip. The ground colour, and 

 the reddish tint of the anterior extremity usually disappear more 

 or less completely in spirit, while the bands become brown or 

 sometimes black. 



Largest living specimen 10 cm. long. In two contracted spirit 

 specimens 42 and 23 mm. long respectively^ the apertures of the 

 mouth are 20 and 12 mm. respectively behind the anterior 

 extremity ; in a third specimen 26 mm. long the genital orifice is 

 4 mm. anterior to the hinder extremity. In none of our specimens 

 are both apertures visible.
