ON THE GENERIC POSITION OF BULIMUS GALERICULUM MOUSS. 
BY H. A. PRESBRY. 
This species was described by Mousson in his Land- und Stisswasser- 
Mollusken von Java, 1849, p. 34, from near Pardana, Java, from a 
single specimen collected by Zollinger. In von Martens’ edition of 
Die Heliceen the species is placed in Geotrochus, with the Cingalese 
forms later referred to Beddomea. Pfeiffer in his arrangement of 
the land snails in Malak. Blitter for 1855, p. 162, makes galericu- 
lum the sole species of a new section of Bulimi, Pseusopartula. 
The name he later corrects to Pseudopartula. In the Nomenclator 
Hel. Viv. he includes with galericulum in Pseudopartula (which is 
here made a subsection of Geotrochus), the New Caledonian species 
grouping around B. sinistrorsus Desh. 
It is evident from this that B. galericulwm is the type of Pseudo- 
partula. On comparison with Ariophanta dohertyt Aldr., I find that 
that species also belongs to the same group ; and here likewise must 
be placed Helix nasuta Metc., which has the same conchological 
features. As to the systematic place of Pseudopartula, I am in 
doubt. In the absence of information upon the soft anatomy, the 
group might be placed either next to Papwina in Helicide, or in the 
Bulimulide or the Zonitide, although it is evident that it has no 
affinity with the typical Ariophantas. Conchologically, it is well- 
characterized by the trochiform, sinistral, obliquely perforate shell ; 
thin in texture, milky subtranslucent, the surface with fine spiral 
incised strie, apex smooth and blunt, aperture extremely oblique 
and with well-reflexed peristome. The species are:
