4. Diaspira Birói n. g. n. sp. 
(Fig. 1.) 
Shell dextral, tubiform, with free whorls, forming a regular conic 
spiral ; thin, light yellowish white, spire depressed conic ; whorls 3 3 A> 
free, except the embryonic nucleus, obliquely extremely 
fine striated, with 4 acute keels, the 1. along the line 
of the suture in normal shells, the 2. and 3. above and 
under the periphery respectively, the 4. on the under 
r,. side (on one specimen a weaker keel between the 2. 
Diaspwa Biroi. v r 
and 3. present), embryonic nucleus not keeled ; aperture 
irregularly pentagonal, peristome somewhat expanded, 
double, inner margin stronger and more prominent than the outer 
one. Operculum : ? 
Diam. 3*84—4 mm., alt. 2*89—3*1 mm., apert. 1*42 — 1*47 mm. 
German New Guinea : Stephansort, in woods, under fallen leaves. 
3 specimens. 
I regard for the present this interesting species as representing a 
distinct genus, though I am noth quite convinced, whether it does not 
belong to Ditropopsis E. A. Smith. It differs from this latter chiefly 
by its free whorls and its aperture, but agrees with it in most of its 
other characters. I cannot decide in this question since I have not had 
the opportunity of comparing this form with a specimen of Ditropopsis, 
but I could use only the description and figure. It cannot be regarded 
as excluded that Diaspira Bírói stands in the same relation to Ditrop¬ 
opsis papuana E. A. Smith, as Heteropoma aries Mlldff. to Hetcro- 
poma meridionale (cfr. Möllendorff, Berichte Naturf. Ges. Senckenb.. 
1890, p. 265). If it be the reality then Diaspira must be regarded natu* 
rally as a synonym for Ditropopsis E. A. Smith.
