100 TRUNCATELLINA OF SOUTH AFRICA. 



sions given do not refer to the type, which, measures : height 

 1.82, width 0.83. 



"It may be noted that while the height of inconspicua is 

 greater than that of the type, the width is less. As this atten- 

 uate form has so far only been met with at Dargle, it may 

 well be a local race" (Burnup). 



Dubious, lost Species. 



Pupa haploa Melvill & Ponsonby. PL 9, fig. 22. Shell 

 oblong-pyramidal, very thin, apex blunted; whorls 7, ventri- 

 cose, longitudinally finely striate throughout, impressed at 

 the suture ; aperture oval ; peristome a little thickened, simple. 

 Length 1.7, width .75 mm. 



Pretoria. A very small oblong species, with simple and 

 very slightly thickened peristome (M. & P.). 



A small, simple-mouthed species, of which the type only 

 occurred, unfortunately mislaid soon after description fifteen 

 years ago. No example has since come to hand. Seemingly 

 allied to P. pretoriensis M. & P. (M. & P., 1908).

 pi. 3, f. 7; (8), i, 1908, p. ll. Jaminia haploa (M. & P.),

See note under the following species. 



Pupa psichion Melvill & Ponsonby. PL 9, fig. 23. Shell 

 umbilicate, rather obese, minute, pale brown, apex obtuse; 

 whorls 6, tumid, somewhat flattened ; aperture rounded ; peri- 

 stome thickened, simple. Length 2.5, width 1.5 mm. Pre- 

 toria. A minute species, like haploa (M. & P.), but the whorls 

 are more tumid and only 6 in number. Mouth round, peri- 

 stome simple, toothless, and without plaits (M. & P.). Type 

 "no longer in existence, having been accidentally broken" 

 (M.&P.). 



Pupa psichion M. & P., Ann. Mag. N. H. (6), xiv, 1894, p. 

 93, pi. 1, f. 8; (8), i, 1908, p. Sl.Jaminia psichion (M. & P.), 

 CONNOLLY, Ann. S. Afr. Mus., xi, 1912, p. 285. 



The diameter assigned suggests Pupilla. Neither this nor 

 the preceding species are known to Burnup. Connolly writes : 



"It appears advisable to transfer both the foregoing to the 

 list of doubtful species. P. haploa was founded on a single 

 specimen, which can only be regarded as lost, since it has 

 proved quite impossible to trace its whereabouts. In the case 

 of psichion, the type, the only known specimen, is so hope-
