sent the lateral surfaces of G. subquadrangidata. I have 

 much pleasure in naming the species after Mr. George Howes. 

 Locality. — Invercargill bush. Three specimens, one alive 

 and two in spirit ; collected by G. Howes, Esq. 



Geoplana suteri, Dendy. 



Invercargill (bush). — One specimen; collected by G. Howes, 

 Esq. The species is immediately recognised by the peculiar 

 arrangement of the six narrow dark lines on the dorsal surface. 

 The present specimen (in spirit) shows a differentiation of the 

 ventral surface into three longitudinal zones of about equal 

 width, the outer ones distinguished by a brownish tint and 

 very sharply defined from the paler median zone. Traces 

 ■of a similar differentiation are visible in one of my spirit speci- 

 mens from Dunedin. 



Toitoi, Southland. — Coll., Miss J. G. Rich. Two speci- 

 mens in a bad state of preservation (in spirit), but showing 

 clearly the differentiation of the ventral surface into three 

 longitudinal zones of about equal width, the two outer being 

 of a darker tint than the median one. Body nearly oval in 

 transverse section. 



Geoplana cooperi, n. sp. 



Body (in spirit) more or less oval in section, more or less 

 flattened both dorsally and ventrally ; rather blunt at both 

 extremities. The larger of the two specimens measures about 

 18 mm. in length by 3-5 mm. in breadth, with the genital 

 aperture 6-5 mm. and the peripharyngeal aperture 7 - 5 mm. 

 from the posterior extremity. Eyes numerous, arranged much 

 as usual in the genus. 



The colour of the dorsal surface (in spirit) is brownish- 

 yellow, with five conspicuous, nearly black, longitudinal stripes 

 equidistant from one another. The median dark stripe is more 

 intense in colour, better defined, and may be-somewhat broader 

 than the others ; it appears to be made up of two parallel 

 stripes placed close together side by side, there being (at any 

 rate in one specimen) an indication of an extremely fine pale 

 line down the middle. The outer edge of the outermost stripe 

 is marginal. The bands of ground-colour between the dark 

 stripes are about equal in width to the stripes themselves, and 

 contain a few irregularly scattered minute specks of the 

 darker colour by more or less intense concentration of which 

 the dark stripes themselves seem to be made up. 



The true ventral surface is pale-yellow without markings, 

 but it is separated from the dorsal surface by well-defined 

 lateral bauds about half as wide as the ventral surface, and 

 distinguished by a fine dusting of minute brown specks, visible 

 under a lens.
