156 HELIX-HADRA. 



Pfeiffer figures as a variety of this species a form which is larger, 

 more elevated, unicolored chestnut brown except for the sutural 

 band, becoming lighter above, (see pi. 22, fig. 57). 



Compare H. Uomfieldi, a form from the mainland of which 

 .gratiosa may prove to be a variety.

The first specimen I saw of this species, I was inclined to regard 

 as a variety of Helix gratiosa Cox. I have seen three specimens 

 since then, one in Dr. Cox's collection, one in Mr. Hargraves, and 

 the specimen in my own which I exhibit to-night to the Society, and 

 for which I am indebted to Mrs. Coxen, of Brisbane. It differs from 

 H. gratiosa in being a heavier and thicker shell, in having a thick, 

 white, and reflected peristome, and in being of a violet colour with- 

 in the aperture. I have named it after my friend, Mr. K. Ethe- 

 ridge, Jr., of Edinburgh, F. G. S. (Brazier.} 



H. MACLEAYI Cox. PI. 19, figs. 28, 29, 30. 



Shell globose, imperforate; epidermis very thin, light grayish, 

 tinged with yellow or green ; encircled by a distinct narrow chest- 

 nut band just above (almost upon) the periphery, and another 

 narrower and subobsolete one just below the white-margined suture; 

 lip, columella and parietal wall deep chestnut.
