median stripe. The peripharyngeal aperture in spirit is some- 

 what behind the middle, and the genital rather nearer to it 

 than the posterior extremity. 



Geoplana iris, n. sp. 



_ Closely resembling G. graffii, to which it is evidently nearly 

 alHed, in size and shape and in the general markings of the 

 dorsal surface, but differing strikingly in the details of pattern. 

 In the mid-dorsal line is a rather narrow pale band of brownish- 

 yellow or orange, sometimes edged with iridescent green. On 

 each side of this is a broad band of dark chocolate-brown, in 

 all specimens edged on the outside with iridescent blue, and 

 -about twice the width of the median band. This is followed 

 again by a narrow marginal band of orange, which may also 

 have greenish iridescence on its outer edge. The ventral sur- 

 face is pale, dull orange, without markings. The anterior tip 

 is dull-orange or dark pinkish-browa. The peripharyngeal 

 aperture is decidedly behind the middle, and the genital about 

 half-way between it and the posterior end. 



Geoplana inaequalistriata, Dendy. 



This species was originally described from a single speci- 

 men found crawling on an asphalt path near Christchurch, 

 and it therefore gives me peculiar satisfaction to be able to 

 record the discovery of a fine specimen in its native haunts, 

 beneath a rotten log near the edge of the Afford Forest. 



When at rest it was broad and flattened; when crawling, long 

 but fairly broad, broader behind than in front, strongly convex 

 above, flattened or concave below, measuring about 80mm. by 

 5mm. Dorsal surface brownish-grey with white stripe and 

 dashes arranged exactly as in the type. Ventral surface white, 

 with abundant small brownish-grey specks, which are absent 

 from the prominent narrow margins, and almost absent from 

 a narrow median band. Anterior tip pink. Eyes as usual. 

 In spirit the body contracts but little. The ventral surface 

 is slightly concave, with very prominent margins, the dorsal 

 surface convex. The peripharyngeal aperture is situate de- 

 cidedly behind the middle, but well in the middle third, and 

 the genital aperture is at about one-third of the distance from 

 it to the posterior end. The white markings became, in parts, 

 distinctly yellow in spirit. 



[Since the above was written I have found, on 30th June, 

 another specimen of G. inaqualistriata in my garden at St. 

 Albans, where the type specimen was obtained. The last- 

 found specimen was lying under a large stone. I placed it in 

 a tin collecting-box with some parsley leaves and left it on the 

 verandah, intending to preserve it in spirit next day. There
