new Species of Oleacina kc. 213 
Distinguished from sanis, Bens., by its less rapidly in- 
creasing whorls and its angular funnel-shaped umbilicus ; 
pseudosanis is not quite so flat, generally smaller, and has 
not so wide an umbilicus. 
Trochomorpha (Videna) pseudosanis, sp. n. (Nevill, MS.). 
(Pl. VI. figs. 5, 5a, 56.) 
Shell openly umbilicate, dark brown, obliquely striated 
above and below; whorls 54, slowly increasing, suture with 
a narrow well-defined margin, last whorl sharply keeled ; 
aperture oblique; peristome scarcely thickened. 
Maj. diam. 13 millim., height 5 millim., width of umbili- 
cus 4 millim. 
Type in British Museum. 
Loc. Port Blair, Andaman Islands. 
This species is allied to andamanica, but is generally 
smaller, has a slightly more conical spire, a whorl less, and 
the umbilicus is narrower and not so sharply angled at the 
margin. 
Bulimulus (Drymeus) Baront, sp. n. 
(Pl. VI. figs. 8, Sa, 86.) 
Shell slightly umbilicate and broadly rimate, solid, either 
light brown with a narrow whitish spiral band at the suture 
or dirty white with spiral bands of a light brown colour; the 
fine longitudinal strie or lines of growth are irregularly 
microscopically wrinkled ; apex blunt, apical whorls whitish, 
with close-set minute thimble-like punctures ; whorls 61-63, 
convex, the last rather suddenly deflected, giving the umbili- 
cal area a rimose character; aperture ovate, dark brown 
within, one half to three fifths the length of shell; lip 
broadly expanded, outer margins white; parietal callus very 
thin. 
Long. 34 millim., maj. diam. 22 millim.

Type specimens (three) in British Museum. 
Loc. Rio Yonan, Peru, 4000 feet (C. 7. Baron). 
Resembles D. proteus, Brod., in its variableness of form 
and coloration, but has not the characteristic granular sculp- 
ture of that species. It is closely allied to cora, d’Orb., but 
is smaller, with more conical spire, and of a more solid 
growth.
