and sometimes a more or less definite pale stripe above each 

 margin, but the latter is commonly wanting. Minute specks 

 •of darker brown are abundantly scattered all over the dorsal 

 surface (including the pale stripes). There are also less 

 numerous bluish(?)-white spots more or less surrounded by 

 very dark-brown shading. These white spots are largest and 

 most conspicuous along the margins of the pale median band, 

 where there may be some fifteen on each side, but quite 

 irregularly arranged, and with the dark shading round their 

 ■outer margins only ; they are usually entirely absent from 

 the median band itself. The ventral surface is pale-brown, 

 closely and minutely speckled with darker brown, sometimes 

 with an indication of a paler narrow median band. Eyes 

 numerous, but apparently absent from the extreme anterior 

 end. 



In spirit the body is flat below, convex above, with narrow 

 lateral margins ; commonly rather broader behind than in 

 front. A full-grown specimen measures, in spirit, 24 mm. in 

 length by 6 mm. in greatest breadth, with the genital aper- 

 ture 7 mm. and the peripharyngeal aperture 11mm. from the 

 posterior extremity. 



The spotted appearance of the dorsal surface in this variety 

 is extremely characteristic.

Geoplana graffii, var. nodosa, nov. var. 



Shape as usual in G. graffii. A typical spirit specimen 

 measures about 40 mm. by 55 mm., with the genital aperture 

 125 mm. and the peripharyngeal aperture 5 - 5 mm. from the 

 posterior extremity. In this specimen the dorsal surface in 

 life was dark-brown, with a narrow, interrupted, nodose, 

 greenish-yellow mid-dorsal line. Ground-colour flecked with 

 very minute specks of pale iridescent blue. Margins of body 

 occupied by a very narrow but well-defined band of pale 

 yellowish-brown, and flecked with small dashes of pale 

 greenish-yellow like those of the mid-dorsal line, but smaller. 

 Ventral surface light-brown, closely and finely mottled with a 

 darker tint, with no pale median band. 



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

 but differs in the typically well-defined narrow marginal pale 

 bands and the more distinct nodose mid-dorsal line ; perhaps 

 also in the greater breadth and altogether larger size of the 

 body. Some specimens show traces of a pale median ventral 

 band. The variety attains a large size, one specimen in spirit 

 measuring 50 mm. by 10 mm., and is subject to slight varia- 

 tion in colour-markings which make it impossible to define it
