Geoplana cucullata, Dendy. 



Near Jackson's, on the Teremakau (West Coast Road). — 

 February, 1898. One typical specimen, found under wood. 

 When at rest very broad and flat, with a very slight median 

 dorsal longitudinal ridge. The hollow under the anterior 

 end, conspicuous in spirit, was not noticeable in life. The 

 colour of the dorsal surface in life was pale-orange, finely 

 speckled with darker brownish-orange, and with a faint 

 indication of a narrow median longitudinal band of the paler 

 colour ; anterior tip dorsally dark-brown, ventrally colour- 

 less for some distance ; ventral surface pale-orange, finely 

 speckled with darker brownish-orange. Length in spirit, 

 21 mm. ; breadth, 7 mm. 



Near Mr. Garvey's House, Clinton Valley, Head of Lake Te 

 Anau. — In this locality I obtained two specimens in rotten 

 trees, both typical. The larger one is thus described in my 

 notes. " At rest very broad and flat. Dorsal surface in life 

 nearly uniform gamboge-yellow, rather paler in the middle 

 line. Numerous thickly scattered minute brown specks 

 visible under a pocket-lens. Anterior tip coloured like rest 

 of body. Eyes numerous, as usual. Ventral surface rather 

 paler than dorsal. Nearly uniform yellowish-brown. Move- 

 ments very sluggish." In spirit the hood-like or beak-like 

 form of the anterior extremity is very conspicuous. 



Geoplana munda, Fletcher and Hamilton. 



The two specimens agree very closely indeed with the 

 well-known and common Australian form. I received them 

 both in spirit, but, as usual in the species, the colours are well 

 preserved. The Invercargill specimen is about 17 mm. long 

 and 3 mm. broad, with the genital aperture about 5'5 mm. 

 and the peripharyngeal aperture about 7 - 5 mm. from the 

 posterior extremity. Thus the peripharyngeal aperture is a 

 little further back than usual in the species, but this may be, 

 in part at any rate, due to unequal contraction.* The body is 

 strongly convex above, flattened below, tapering rather more 

 .gradually in front than behind. The ground-colour of the 

 dorsal surface (in spirit) is yellowish-brown, with four distinct 

 longitudinal stripes of dark chestnut-brown — viz., a pair of 

 very narrow well-defined stripes, one on each side of a very 

 narrow median stripe of ground-colour, and a pair of much 

 broader stripes, one halfway between each narrow dark stripe 

 and the margin of the body. The narrow dark stripes have 

 their outer margins uneven, the broad dark stripes have both 

 margins very uneven. In the pale ground-colour between the 



* The Toitoi specimen is slightly damaged, and I have not quite 

 satisfied myself as to the apertures.
