40 ADDITIONAL OBSERVATIONS ON 



of an expedition made to that locality in company with Mr. A. W. Howitt and 

 Mr. A. H. S. Lucas in December, 1890. I have much pleasure in naming the species 

 after the leader of the expedition. 



In the shape of the body and the markedly posterior position of the apertures 

 Geoplana howitti resembles G. fietcheri. 



20. Geoplana liicasi, Dendy. 



(PI. IV., Fig. 4.) 



1 found a single specimen of this interesting species under a log near Mount 

 Wellington, Gippsland, on the same occasion and in the same locality as G. howitti. 

 As I had not before seen this Planarian alive I was very glad of the opportunity of 

 making careful notes of the appearance of the living animal, and I am also able to 

 give a figure of the natural colour. 



In life the dorsal surface is white, with dark grey or black markings arranged as 

 follows : — There is a rather narrow median stripe of black and the remainder of the 

 dorsal surface is thickly flecked with small specks and longitudinal dashes of dark 

 grey. On either side of the median black line these specks and dashes are absent, 

 or nearly so, leaving a very narrow band of almost clear ground colour, then they 

 appear comparatively large and very close together and more in irregular longitudinal 

 dashes which seem to be formed each of a number of small dots. Towards the 

 margin of the body the dots and dashes get smaller and scarcer. The horse-shoe- 

 shaped anterior extremity is reddish brown. The ventral surface is greyish white, 

 with no markings. 



When crawling the worm measured about 60 mm. in length. 



The specimen after preservation in spirit closely resembles the spirit specimens 

 from Croajingolong originally described. The eyes appear to extend (in abundance) 

 for an unusual distance down the sides of the body, if not along the entire length of 

 the animal, but it is difficult to be certain on this point owing to the resemblance 

 between the eyes and the smaller specks of pigment. 



In concluding these observations I desire again to express my indebtedness to 

 those gentlemen who have kindly assisted me in collecting specimens of Land 

 Planarians, viz., the Rev. W. Fielder, Mr. Officer, Mr. Avery, Mr. Fiddian, and Mr. 

 W. Mann, of the Melbourne University ; Mr. H. R. Hogg, Mr. Hennell, and other 

 members of the Field Naturalists' Club of Victoria.
