702 PROF. ARTHUR DENDY ON^ 



The woim when crawling is long and narrow, convex above 

 and flat below. The gTonnd-colour of the dors.al surface in life 

 I'anges from grey to yellow, but even in the grey specimens it 

 becomes fairly bright yellow in spirit. Minute brown specks 

 are sparsely scattered over the dorsal surface and tend to aiTjvnge 

 themselves in a very narrow median stripe. The horseshoe- 

 Kha.ped anterior tip is brown or brownish pink, and the ventral 

 sui'face neai'ly Avhite, without markings. The eyes are arranged 

 as usual. In spirit the body is narrow, more or less flattened, 

 especially ventral!}-, and with fairly well pronounced lateral 

 margins. 



In one specimen (in spirit) the pei'ipharyngeal aperture is 

 Lated well in front of the middle of the body, and the genital 

 aperture rather nearer to it than to the posterior end. This is 

 the only one in which both apertures are visible, but in another 

 the peripharyngeal aperture seems to be about central ; Imt nf 

 course the position of the apertures is influenced by the lelalive 

 state of contraction of the two ends of the body. 



One of the four specimens is much larger tlian the other three, 

 measuring in spirit about 32 mm. in length by a shade over 

 3 xxim. in greatest breadth. The smaller ones in sj)irit measure 

 about 19 mm. in length by 2-5 mm. in breadth. In life one of 

 them measured about 32 by 2 mm. 



I think that the specimen w-hicli I described [1892] under the 

 name Geojjlana sp., fi'om near Hobart, pr'obably belongs to this 

 species. Von GrafF [1899] referi-ed this specimen to the 

 "Victorian O. quadrangulata var. toellingtoni, but there was A'ery 

 little justification for so doing, or, I fear, for my own comparison 

 of it with G. qaadraiigidata and G. ventrojmnctata.
