THE NAUTILUS. 93 
A NEW PERUVIAN CHIONE. 
BY IDA S. OLDROYD. 
CHIONE MERIDIONALIS n. sp. Plate IV, figs. 3, 4. 
Shell of medium size, somewhat triangular elongate, quite 
flat; concentrically laminated, the laminze crenated, erect, ten 
in number, evenly spaced; interstices radiately ridged with fine 
ribs bundled in threes, evenly spaced. Ligamentary area very 
broadly excavated, with brown markings. Lunule narrow, 
elongate, faintly marked with brown and circumscribed by an 
incised line. Nymphs smooth, like young C. gnidia. Teeth 
smooth. Valve margins crenulate. Ligament inset, but show- 
ing externally. Color cream-white, with brown marking, in- 
terior white. 
It is something like a young C. gnidia in sculpture, but the 
lamine are not scalloped as in that species, and it is a small 
shell compared with that. It is elongate, while C. gnidia is 
ovate. The accompanying plate will show the difference in the 
two species. Figures 1 and 2 are C. gnidia. 
Type locality, Peru. The type is in the University of Cali- 
fornia Museum, locality number 3135. One specimen is in the 
Stanford University collection. 
LAND SHELLS OF SOUTHERN FLORIDA. 
BY E. G. VANATTA. 
The following species of land shells were picked from leaf- 
mould collected by Mr. Clarence B. Moore in Southern Florida 
during the winter of 1919 and 1920, at stations not recorded in 
THE Navutitus volumes XIX (1905), page 40; XXI (1908), 
page 99; X XVI (1912), pages 16, 81; XX XIII (1919), page 18. 
All the records of Bifidaria contracta Say in those lists should 
be changed to Gastrocopta contracta peninsularis Pils., which 
differs from the typical contracta as indicated on page 17 of THE 
Navtitus, Vol. XX VI (1912).
