46 THE NAUTILUS. 
NOTE ON BULIMUS HANLEYI AND B. CORONATUS. 
BY H. AS PILSBRY. 
The two Brazilian species mentioned above are thin, unicolored, 
glossy shells, with the spire long, suture crenulated, columella simple 
and foldless, and the outer lip thin and acute. B. Han/eyi Pfr. was 
(with B. recluzianus Pfr.) placed in a new subgenus, Oxycheilus,’ 
by Albers in 1850; but von Martens in 1860 referred it to Orphnus. 
B. coronatus Pfr. was placed by Albers in Leptomerus, but von 
Martens transferred the species to Peronceus, where it has been re- 
tained by subsequent authors. 
The characters of the apical whorls show at once that the refer- 
ence of the species to Leptomerus (a section of Bulimulus) is errone- 
ous; while the structure of the columella and the texture of the shell 
equally remove the species from Peroneus. 
The texture of the shell is that of such South American Stenogy- 
roid species as B. caleareus Born and B. cuneus Pfr., ete. which have 
been called Obeliscus, but for which the name NEOBELISCUS’ is now 
proposed. These, however, have a bulbous, more or less costulate 
apex, without apical dimple. 
For B. Hanleyi and B. coronatus, we suggest the name SyNAP- 
TERPES, the former species being the type. The conchological feat- 
ures of the new group are: an oblong-turrited, thin, glossy, more or 
less vitreous shell with crenulated sutures, rather obtuse (but not 
bulbous) nuclear whorl with comma-shaped apical dimple, the aper- 
ture long-ovate with thin, sharp outer lip and simple columella, not 
truncate below, its edge narrowly reflexed above. 
I do not know that any species except the two mentioned belong 
to this group. Its systematic position, if we judged by shell char- 
acters, would seem to bein the Achatinide near Neobeliseus; but if 
Binney’s identification’ is correct, the jaw and dentition are consider- 
ably like those of some forms of the genus Strophocheilus, and, there- 
fore, as far as their testimony goes, indicate a position for the group 
in the Helicide. )

2 Obeliscus was restricted by Gray in 1847 (P. Z.S., p. 176) to B. obtusatus 
Gmel., a Madagascar species for which the name C/avatoy was proposed in 1860. 
Humphreys had previously used Oée/?scus in another sense.
