160 GASTBOCOPTA, AUSTRALIA.

Various other localities are given by Hedley and Musson, 

 but they may apply to allied forms of similar appearance. 

 At Calliungal it was associated with G. mussoni. 



The specimens taken by Mr. Hedley at Mapoon are all 

 smaller than those from Calliungal. This is probably an in- 

 digenous Australian race, perhaps identical with G. moorecma 

 Smith. 



96. GASTROCOPTA MOOREANA (Smith). PL 30, fig. 4. 



Shell short, cylindroid, rimate, brownish-corneous, whorls 5,

 apex. Aperture rounded, provided with 5 unequal teeth (two 

 palatal, one columellar, two parietal), one-third the total

"The largest tooth is that situated on the whorl midway 

 between the ends of the peristome. It juts out into the aper- 

 ture and points between the two palatal denticles, which are 

 about the same size as that on the columella. The fifth tubercle 

 is at the insertion of the labrum. Named in honour of Capt. 

 W. U. Moore, R. N., in command of the Penguin" (Smith). 



The figure given by Mr. Smith is too small and indistinct 

 to show specific characters. It is copied in my fig. 4. Mr. B. 

 B. Woodward, who has kindly looked at the type specimen, 

 informs me that the columellar lamella enters horizontally. 

 Later I hope to illustrate one of the type lot.
