TURBELLAEIA. 



Geoplana moseleyi, s'g. no v. 



Shape of the body, as in G. traversii. Mouth situated behind the middle ; 

 generative orifice half way between it and the posterior extremity. Eyes 

 numerous round the anterior end, forming a line which expands into two 

 patches on each side. Upper surface dark grey, speckled with white, 

 bounded on the sides by a lateral stripe of brown ; a broad dorsal stripe, 

 orange, margined with brown, the brown separated from the orange by an 

 interrupted narrow black line ; lower surface brownish white. 



Dunedin, in the bush, under dead trees. 



The body is covered externally with very deHcate cilia, which require a 



1 objective to see. 



Genus Rhynchodemus, Leidy. 



Body much elongated. Eyes two. Mouth cyhndrical, elongate. Ex- 

 ternal longitudinal muscles feebly developed. Ovaries simple, near the 

 anterior extremity of the body. Lateral organs distinct. 

 R. testaceus, sp. nov. 



Body elongate, depressed, tapering to an acute point at either end ; 

 broadest part behind the centre ; upper surface convex, finely transversely 

 striated ; lower surface flat, without any ambulacral line. Eyes none. 

 Mouth about two-thirds of the whole length from the anterior end ; gene- 

 rative orifice half way between it and the posterior end. Upper surface 

 cherry-red to brick-red ; margin and ventral sm'face yellow. Length some- 

 times three inches. 



Dunedin and Wellington, under stones, or in the ground. 



I have not been able to detect either eyes or cilia on this species. I 

 refer it provisionally only to Rhynchodemus, in the absence of full informa- 

 tion about the genera of land Planarians. 



Nemeetidea. 



Genus Borlasia, Oken. 



Body long, sub-cylindrical or flattened, obtuse at the extremities ; head 



simple, no eyes ; proboscis terminal, with a longitudinal pit on each side ; 



mouth inferior, longitudinal, not terminal ; reproductive orifice in a tubercle
