12 TESTACELLID^E. 



from the Wynaad measuring 8, 6, and 4 mm. may be a still larger 

 form. 



19. Streptaxis concinnus, Blf. J. A. S. B. xlix, pt. 2, 1880, p. 203, 



pi. 2, fig. 11. 



Subumbilicated, smooth, striated, whitish ; spire convex, very 

 low ; whorls 5|, convex ; penultimate rounded, completely hidden 

 by the broader last whorl when the shell is looked at from beneath 

 in the line of the axis of the upper whorls ; last whorl tumid and 

 polished below, compressed around the umbilicus anteriorly, con- 

 stricted by indentations behind the peristome ; aperture with outer 

 and coluinellar margins nearly straight and converging outwards, 

 rounded at the base ; peristome white, expanded, but little curved 

 back at the angle ; parietal lamellae 2, both elongate, the inner long, 

 and bent inside ; teeth in peristome 5, two columellar, one small 

 near the umbilicus, the other double ; one transverse and lamellar 

 at the base and two inside the outer margin. 



Length 6|, breadth 4, height 3 mm. 



Hob. Balaraugam Hills, Mysore. 



This is very near S. watsoni, but distinguished by the penulti- 

 mate whorl not projecting below. 



20. Streptaxis scalptus, Blf. P. Z. S. 1899, p. 766, pi. 50, figs. 8, 9, 10. 



Shell subunibilicated, moderately depressed, ovate ; costulately 

 striated above, smooth beneath, waxy, whitish ; spire depressedly 

 conoid; whorls 5J-6, convex; penultimate rounded, projecting 

 less than half its breadth beyond the last whorl when viewed from 

 beneath ; last whorl moderately convex, compressed laterally near 

 the aperture, constricted by indentations behind the peristome ; 

 aperture semioval, contracted by one or (more often) two parietal 

 lamellaB and by 3, 4, or 5 subequal palatal teeth, most commonly 4, 

 one columellar, one distal, and two in the right margin. 



Length 10, breadth 7, height 5| mm. 



Hob. Kolamalai Hills, Salem district (Beddome) ; Balur in Kadur 

 district, Mysore (Daly}. 



A specimen from Torna Hill, near Poona, Deccan, measuring 

 11 J X 8| x 6 mm., may perhaps be referred to this form. 



21. Streptaxis cingalensis, Bs. A. M. N. H. (2) xii, 1853, p. 91 ; 



Pfr. Mon. Hel. iv, 1859, p. 333 ; vii, p. 496 ; H. $ T. C. I. 1876, 

 pi. 98, figs. 2, 3 ; Nee. Hand-l. i, 1878, p. 4. 



Similar to S. laycmtianus (p. 5), but slightly larger, with the 

 last whorl less excentric and rather more convex beneath ; the 

 deep sinus in the peristome at the angle always ends in a tubercle 

 on the parietal wall, and there are two small tubercular teeth 

 inside the peristome, one in the middle of the outer margin, 

 opposite the ridge of the parietal plait, the other at the base of the 

 columellar margin.
