74 ON THE VICTORIAN LAND PLANARIANS. 



situate in about the middle or a little behind the middle of the ventral surface. The 

 ground colour of the dorsal surface is pale yellowish brown. There is one very fine, 

 median, dark brown stripe, and a very broad lateral dark brown stripe on each side of 

 it and separated from it by a fairly wide interval of ground colour. The lateral 

 stripes are rather ill-defined at their outer edges, where they touch a band of the 

 ground colour splotched with darker brown. The ventral surface is i)ale yellowish 

 brown, slightly mottled, or white. The largest of the three specimens which I have 

 seen was about 40 mm. in length and 3 mm. in greatest breadth when crawling. 



I have called this beautiful Planarian after my wife, who has greatly assisted me 

 in my search for cryptozoic animals.

6. Geoplana lucasi, n. sp. 



The body (in spirit) is very broad and much flattened, especially on the ventral 

 surface ; very blunt behind and tapering more gradually in front. The opening into 

 the peripharyngeal chamber is rather behind the middle of the ventral surface and 

 the genital aperture about halfway between it and the posterior end of the body. 

 The dorsal surface, in the living animal, was of a creamy white colour, with a narrow 

 dark brown median stripe and on each side of the stripe numerous close-set, narrow, 

 discontinuous, wavy longitudinal streaks of brown over all the remainder of the dorsal 

 surface. There is no record of any markings on the ventral surface of the 

 living animal. 



I received three specimens of this worm in spirit from Professor Spencer, from 

 Croajingolong. The largest measures (in spirit) about 40 mm. in length and 8 mm. 

 in greatest breadth, and came from a height of 4000 feet on the top of the coast 

 ranges. I have named the species after Mr. A. H. S. Lucas, M.A., B.Sc. 



Locality. — Croajingolong (Victoria) . 



7. Geoplana vi'mahoiii, n. sp. 



Body (in spirit) strongly convex on the dorsal surface, flattened on the ventral, 

 tapering gradually towards the anterior end and much more suddenly towards the 

 posterior. Opening into the peripharyngeal chamber situate at about the junction of 

 the middle and posterior thirds of the body. Genital aperture nearer to the posterior
