the difference is sufficiently striking and constant in actual 

 specimens to merit the use of a distinctive varietal name. 



I found four specimens of this variety at Otira, and six 

 near Lake Mahinapua. 



Geoplana grafl&i var. otiraensis, nov. 



Body when at rest in life broad and much flattened, but 

 convex above and somewhat triangular in section. When 

 crawling, tapering very gradually in front, much less so be- 

 hind. In spirit, flat or slightly concave below, more or less 

 arched above, broader behind than in front, tapering very 

 gradually to the narrow anterior extremity, more suddenly 

 to the blunter posterior extremity. 



A fair-sized specimen, in spirit, measures 33mm. in length 

 by 6mm. in greatest breadth. 



The peripharyngeal aperture, in spirit, is only very slightly 

 behind the middle of the body, and the genital aperture only 

 very slightly behind the junction of the middle and posterior 

 thirds. 



Dorsal surface in life dark-grey, intensified to black in the 

 middle line, flecked all over with small whitish, greenish, or 

 yellowish specks, varying in distinctness in different specimens. 

 Anterior tip dark -grey. Ventral surface brown, minutely 

 speckled with a darker tint, and with a paler-coloured narrow 

 median band. Very narrow brown margins. 



Two somewhat larger specimens, apparently of the same 

 variety, have the pale median ventral and dark median dorsal 

 bands either absent or very obscure, and one of them has an 

 intensified supra-marginal band on each side of the dorsal 

 surface. 



Eyes numerous, and arranged as usual, but difficult to 

 make out owing to the dark colour of the body. 



This variety comes very near to G. graffii var. soviersii, 

 described in Part II. of these notes; but the present specimens 

 are much larger, and differ slightly in pattern from those of 

 the Springburn variety. 



Five specimens were obtained at Otira, and one near Lake 

 Mahinapua. 



Geoplana moseleyi, Hutton. 



I have received from Mr. Suter several specimens pre- 

 served in spirit which I have little doubt are referable to 

 Hutton's species. They were collected at Dunedin, where 

 Hutton's original type was also obtained. They agree very 

 closely with Hutton's description, but the degree of develop- 

 ment of the median dorsal stripe is variable, sometimes broad 

 and sometimes very narrow, while the " interrupted narrow
