STREPTOSTYLA. 95 
linearis, infra paullulum dilatata, margine externo infra medium leviter antrorsum arcuato, columella 
crassa, valde torta, aperta. 
Tong. 14, diam. 5 ; apert. long. 93, diam. superne 2, infra 14 millim. 
Hab. W. Mexico: Sayula, State of Jalisco (Hége). 
Only one specimen. Resembles in many points S. coniformis, but is much smaller 
and yet very thick (so that it cannot be young); it is also considerably more slender, 
with proportionately longer spire. For comparison, a young specimen of G. coni- 
formis is figured (fig. 14). 
d. Lurgide. 
12. Streptostyla obesa, sp.n. (Tab. V. figg. 12, 12a.) 
Testa oblongo-ovata, leviter striatula, nitida, aurantio-flava, unicolor; sutura submarginata, anguste alba; 
spira conica, acutiuscula; anfr. 8}, regulariter crescentes, leviter convexi; apertura dimidiam teste alti- 
tudinem superans, oblique lanceolata, margine externo inferius antrorsum arcuato, columella subperpendi- 
culari, leviter torta. 
Long. 38, diam. 18; apert. long. 18, diam. 9 millim. 
Hab. Honpvras: from a shell-dealer (Mus. Berol.). 
Nearly allied to S. turgidula, Pfr., but distinctly broader (diameter equal to the 
length of the aperture); coloration more orange, and without darker varices; the 
suture also in the last whorl is regular, not indented by stoppages of growth, and 
the white colour of the suture itself more conspicuous. I have seen only one 
specimen.

S. GuatemaLa: San Agustin * (Bocourt*); Hacienda Helvetia 3000 feet, Hacienda 
Buenavista 3500 feet, both in Upper Cholhuitz, and Hacienda Germania near 
* There are several places of this name in Guatemala; the one on the Pacific slope is probably intended, 
one at least of Bocourt’s species being recorded from the “ San Agustin, Dep. of Solola.”
