Terrestrial Planirians from Japanese Territories. Q 



The body, when tlie worm was hving, was slender and liad 

 the lateral margins even and nearly parallel for a large part of their 

 length, but was tapering at both the anterior and posterior ends, 

 which were bluntly pointed. The ventral surface is made up of 

 the shghtly raised sole, extending over tlie whole surface. The 

 specimen was 24 mm. in length and 1-5 mm. across the widest 

 part of the body. 



The ground colour of the dorsal surface is of a dark olive-like 

 brown colour and medially marked with a slender dark stripe which 

 loses itself in tlie anterior parts. There occur two pairs of colour- 

 less spots at the lateral sides of the body, a short distance behind 

 the anterior extremity which is dark. Ventrnlly, the dark olive 

 brown colour is continued from the dorsal surface, except for the 

 mid- ventral surface which is pale. 



The eye-spots, numbering about twelve on either side, are 

 arranged round the anterior tip in a single row interrupted by a 

 gap in the middle.

Geoplaaa lapidicola, Stimpson (62', pp. 23, 30. — Diesing (16;, pp. 510. — von 

 Graff (25), pp. 870, 371. * 



This species was first recoi-ded by Stimpson from Loo Choo. 

 No specimen came under my examination. 



" Eilongata, subconvex, post medium parum latior, lateribus 

 fere parallelis, extremitatibus rotundatis; supra grisea, fascia 

 mediana fulva, marginibus pallidis. Ocelli vix numerosi in late- 

 ribus extremitatis anterioris sparsi, majores utrinque 3-4 latero- 

 frontale.s. Long. L2 (30-5 mm.); lat. 0-1 (2-5 mm.) poll".

(PI. I., Fig. 2.— Text Fig. 1.) 



This new species is one of the commonest forms in Central 

 Japan; it was procured in fair abundance in Nikko, at Itaya in 

 Prov. Iwashiro and in the neighbourhoods of Tokyo and Kyoto.
