76 ON THE VICTORIAN LAND PLANAEIANS. 



however, be grey or greenish grey. The two remaining stripes, one on each side, 

 are separated by wider intervals from those nearest to the middle line and are of a 

 very dark brown, almost black colour. The relative breadth of the stripes appears to 

 vary a good deal. The anterior extremity of the body is of the usual brownish pink 

 colour, into which the stripes merge. The ventral surface is of a uniform yellow 

 colour, a little paler than the ground colour of the dorsal surface. The largest 

 specimen which I have seen alive was about 125 mm. long and 5 mm. in greatest 

 breadth when crawling (Fig. 5). Usually, however, specimens are only about 70 or 

 80 mm. long when crawling. 



I have seen great numbers of this species imder logs and stones at Macedon and 

 I have great pleasure in calling it after Mr. H. E. Hogg, on whose property it is 

 particularly abundant and who first brought it to me in a living condition. 



Locality. — Macedon (Victoria). 



10. Geoplnna sngdeni, n. sp. (Figs. 12, 13, 14). 



Body very narrow and much elongated ; approximately oval in section but 

 somewhat flattened ventrally, more nearly cylindrical than in any other species of 

 the genus with which I am acquainted ; tapering gradually to each extremity. 

 Opening into the peripharyngeal cb amber a little in front of the middle of the 

 ventral surface. Genital opening only a little behind the middle, separated from the 

 opening into the peripharyngeal chamber by an interval of about 10 mm. (in spirit) 

 and from the posterior end of the body by an interval of about 18 mm. The colour 

 of the dorsal surface is bright canary yellow all over except the reddish brown 

 anterior tip ; the ventral surface is of a paler yellow colour. There are no stripes 

 at all. Length when crawling about 70 mm., greatest breadth only about 2 mm. 



This species is rather remarkable for its habit of wandering about in broad 

 daylight, to which I have already referred in my introductory remarks. I have much 

 pleasure in naming it after the Rev. E. H. Sugden, B.A., B.Sc, the Master of 

 Queen's College in the University of Melbourne.

11. Geoplana medioUneata, n, sp. (Figs. 1, 2, 3, 3fl). 



Body long and narrow, oval in section but not very much flattened ; tapering 

 very gradually towards the anterior and more suddenly towards the posterior end.
