low, whereas it is only very slightly descending in our species ; there 

 are also differences in the parietal callus, that of C. Gruneri being much 

 thicker in the upper portion, whereas it is of equal thickness in 

 C. mima ; the latter has the spire very slightly depressed, that of the 

 former is flat. From C. unguiculastra, Marts., it can be separated by 

 its smaller size, its raised callus, and its narrower umbilicus. 



3. Chloritis selenitoides, n.sp. PI. XI, Fig. 9. 



Shell depressed, subgiobose, openly unbilicated, dark brown ; 

 whorls 5, convex, gradually increasing, first three almost flat, last 

 two gradually descending, with obtuse but conspicuous oblique plicate 

 striae ; peristome white, slightly expanded, margins joined by a some- 

 what thickened callus. Diam, maj. 26, alt. 14 mm. 



Hah. — Burn I. 



A distinct species, easily distinguished from others of the genus 

 by its zonitoid form. This and C. mima belong to the hairless forms 

 of Chloritis. 



4. Planispika Adonaean-a, n.sp. PI. XI, Fig. 12. 



Shell depressed, globose, thin, smooth, light horn-colour, umbilicus 

 open to about 2 mm. at its widest part, somewhat constricted behind 

 the aperture; whorls 3|, slowly increasing, convex, last half- whorl 

 descending about 2 mm. ; peristome subcircular, continuous., broadly 

 expanded, equal to half the width of the shell, very oblique, a spiral 

 fold just above the periphery for one-third of a whorl behind the 

 aperture, an indication of another is faintly seen on the basal portion 

 of the peristome. Diam. maj. 12, alt. 7 mm. 



Hah. — Adonara I., Moluccas. 



Easily distinguished from P. eudoptycha, Marts., by its continuous 

 peristome and fewer whorls. 



5. Amphidromus contrariiis, Miill., var ceassa, n. PI. XI, Fig. 8. 



This is similar in shape to the typical form, but is a much more 

 solid shell ; the columella is thick and round, not thin and expanded 

 as in the type ; whilst the aperture is somewhat higher in proportion 

 to the height of the shell, and the interrupted oblique colour- stripes 

 of the type are absent on the last whorl of this species, Diam. maj. 

 20, alt. 40 mm. 



^«5.— Timor I. 



Numerous examples of the typical form were also collected at 

 Timor by Mr. Doherty. 



6. Htpselostoma Doheetyi, n.sp. PL XI, Fig. 17. 



Shell dextral, triangular, umbilicus deep and moderately wide, 

 almost smooth ; whorls 4, first three small, convex, body-whorl large, 

 somewhat depressed in the centre and keeled above and below, 

 slightly ascending ; interior of aperture armed with five teeth, two 

 on parietal wall, two palatal teeth, and one on the columella side of
