238 Transactions. — Zoology. 



(seven) of good - sized specimens agreeing closely with one 

 another in shape and colour ; with the dorsal surface very 

 sharply marked off from the lateral surfaces by acute, slightly 

 prominent margins, and the inwardly sloping lateral surfaces 

 distinguished from the narrow ventral surface by their some- 

 what darker tint and more or less speckled character. Three 

 dorsal stripes as usual, but now (in spirit) the colours are 

 very pale. 



Invercargill. — Nine specimens, mostly very similar to (a) 

 of the original description, found in a garden by G. Howes, 

 Esq. 



Chatham Island. — January, 1901. Abundant (rotten 

 logs). Two specimens referable to var. (a) of the original 

 description, but mostly with tbree well-defined dorsal stripes 

 (one narrow and two broad), and well-defined minute brown 

 specks sparsely scattered on the lateral and ventral surfaces, 

 and sometimes between the dorsal stripes. 



Geoplana howesi, n. sp. 



When crawling very long and narrow ; subcylindrical, but 

 flattened below. In spirit contracts very much, measuring 

 finally 24 mm. long by 35 mm. broad, with the genital aper- 

 ture 4 - 5 mm. and the peripharyngeal aperture 9 mm. from 

 the posterior extremity. The body in spirit is approximately 

 oval in transverse section ; flattened below and sometimes 

 also above ; of almost uniform diameter throughout, but 

 tapering rather bluntly at each extremity. Colour in life 

 pale-yellow all over, except for the pink anterior tip and 

 three narrow longitudinal stripes of dark-brown on the 

 dorsal surface. The median stripe is narrower than the 

 other two, which are about equidistant between the median 

 stripe and the margins. All the stripes are well defined, and 

 they divide the ground-colour of the dorsal surface into four 

 broad longitudinal zones of about equal width. There are 

 no dark specks either between the stripes or on the ventral 

 surface. In spirit the ventral surface shows a differentiation 

 into three longitudinal bands of about equal width * and 

 very sharply defined, the median band being of a paler tint 

 than the others. Eyes numerous, in single series round 

 the horse-shoe-shaped anterior extremity ('? elsewhere). 



This species is certainly nearly related to G. subquadran- 

 gulata, from which it differs in the more elongated body, 

 which is also more oval in section ; in the narrowness and 

 sharp definition of all three dorsal stripes ; and in the absence 

 of dark specks from the ground-colour. The paired ventral 

 bands of ground-colour, darkening in spirit, evidently repre- 



* Tue median baud may be wider than the other two.
