An egg-capsule of this species from a specimen collected at 

 Trevallyn Hills, and laid during transit from Launceston, was 

 about 4 mm. in diameter. It hatched out a few days after being- 

 placed in my vivarium, when 11 young emerged on 1st August, 

 1900. These were 5 mm. long, by about 1 mm. broad at widest 

 part. The colour of both surfaces is milk-white. The anterior 

 tip both above and below is coloured brown through aggregation 

 of brown speckles similar to those on adult. These speckling^ 

 are on both surfaces continued sparingly down the margins, 

 forming ill-defined marginal bands for a variable distance back. 

 Remainder of surface very sparingly dotted with specklings. 

 Orifices not visible. 



Eyes conspicuous, in a single row round the entire margin of the 

 body, somewhat closer together at anterior than posterior end. 



The appearance of the parent worm after laying the above 

 capsule is described and figured in Part ii. of my foregoing paper 

 on Australian Land Planarians. PI. xli. , fig. 6, in present paper 

 shows the position of the opening. It should be mentioned that 

 the peculiar comb-like glandular genital organs there mentioned 

 would, according to Graff's definition, cause this species to be 

 included in his genus Artioposthia. In his monograph he leaves 

 the species in the genus Geoplana, and does not mention the 

 structure of the genital organs. 



In all external characters my specimens agree precisely with 

 Dendy's description, and with Graff's figures in so far as they go. 



Geoplana sanouinea (Moseley). 



This common and widely distributed Australian species has 

 not hitherto been recorded from Tasmania. Dendy (7, p. 370) at 

 first identified a form devoid of eyes as G. alba, Dendy (syn. G. 

 sanguined), but subsequently (6, p. 181, and 8, p- 420) described 

 it as a distinct species under the name of G. typhlops. The 

 distinguishing external feature between the two species is the 

 possession or otherwise of eyes. All the examples from Tasmania 

 examined by Dendy had no eyes, and hence were assigned by 

 him to G. typhlops.
