566 AUSTRALIAN LAND PLANARIANS, 



Gboplana mblanochroa, n.sp. 

 (PL xxxiv., fig. 3.) 



►Specimen in spirit. Dorsal surface uniform black. Ventral 

 surface black at margins, with a pale central band of about one- 

 third of the total width. The whole ventral surface has a purple 

 tinge. 



Eyes quite invisible until a specimen was cut in sections, when 

 they were found to extend in a single row round anterior tip and 

 right down the sides in a sparse row without side grouping, but 

 with an occasional straggler out of the line. 



Length 16 mm. by 1£ mm. in width. Peripharyngeal aperture 

 9 mm. from anterior tip, with genital opening ] 2J mm., or just 

 midway between peripharyngeal aperture and posterior end. 



Hob. — Armadale, Darling Ranges, Western Australia ; in 

 ightly timbered country, in sheltered gullies, under pieces of 

 ironstone (Mr. C. G. Hamilton). 



This curious little planarian bears some resemblance to G. 

 atrata, mihi, (n, p. 105) but is readily distinguished by the 

 absence of the black ventro-median line, and by the greater width 

 of the black marginal bands on same surface. 



Gboplana graminicola, n.sp. 

 (PI. xxxiv., fig. 9.) 



General colour of dorsal surface red-brown. The whole surface 

 covered with specklings of a darker red-brown which tend to 

 collect into an irregular median band, most distinct towards the 

 posterior end. In some specimens the specklings are very thinly 

 distributed, making the dorsal surface much paler than usual, and 

 in a few they are so densely packed as to impart a uniform dark 

 brown tint. 



Ventral surface pale, with no markings except near the anterior 

 tip, where there are a few specklings similar to those on dorsal 

 surface. Eyes few but conspicuous. In a single row round the 

 anterior tip and for a short distance down the sides, spaced some-
