GASTROCOPTA, AUSTRALIA. 159 



New South Wales, on plants, at an early day, and being well 

 adapted to the local conditions, became commonly diffused. 



Mr. Brazier's account follows. 



"Pupa (Vertigo) rossiteri. Shell dextral, rather oblong, 

 thin, shining, nearly smooth, white, hyaline; spire turrited, 

 apex obtuse ; whorls 5%, roundly convex, the last about quar- 

 ter the length of the whole shell; aperture squarely oval, 

 armed with five teeth, one on the centre of the body whorl 

 thickened and of a lamellated form, second on the columella 

 on the upper side rather sharp, third small and thin at the 

 lower part of the columella, fourth on the basal margin of the 

 interior of the aperture thick and elongated, fifth on the 

 inner upper side of the outer lip rather obsolete; peristome 

 slightly expanded, thin. Length 1*4, breadth % lines. 



"Picton; Rope's Creek; Lake Macquarie; and Wingham, 

 upper Manning River, New South Wales. 



' ' This species is often taken for a variety of Vertigo stran- 

 gei Pfr. The true typical species of Vertigo strangei are 

 sinistral, more elongated, and the aperture oval, studded with 

 seven teeth. Dr. Cox, in his Monograph of Australian Land 

 Shells, 1868, figures my species as a variety of V. strangei, in 

 plate 14, fig. 18, 18&; both species are found in company" 

 (Brazier, Proc. Linn. Soc. N. S. Wales, i, 1877, p. 18). 



95a. G. PEDICULUS QUEENSLANDICA n. subsp. PL 26, fig. 2. 



With a general resemblance to G. pediculus (more partic- 

 ularly the Philippine and Hawaiian forms of the species), this 

 race differs by the distinctly smaller teeth, which are both 

 lower and more slender. The basal fold is typically very 

 small, a mere trace ; but it varies from moderately small to 

 entirely absent. The parietal callous is very thin, without a 

 raised edge. The shell is thinner and more fragile than in 

 pediculus. 



Length 2.4, diam. above aperture 1.25 mm. (type, Calli- 

 ungal). 



Length 2.1, diam. above aperture 1.1 mm. (Mapoon). 



Queensland: Calliungal (C. T. Musson) ; Mapoon, at the 

 entrance of Batavia River into the Gulf of Carpenteria (Ch. 

 Hedley).
