THE NAUTILUS. 47 



BUCCINUM STROMBOIDES Hermann. 



Der Naturforscher, XVI, 1781, p. 54, PI. ii, figs. 5, 6. 



This has been recognized as a fossil from the Paris basin and was 

 used by Morch (Journ. de Conch. VIII, 1858, p. 43) as the type of 

 the genus Cryptochorda. 



MUREX DESPECTUS Linne. 



Hermann, Der Naturforscher, XVI, 1781, p. 54, PI. ii, fig. 7. 



Here Hermann professes to figure a sinistral Chrysodomus despectus 

 but Dr. Dall points out to us that the illustration better suits a 

 sinistral C. antiquus. 



A NEW SPECIES OF ANCULOSA. 



BY A. A. HINKLEY. 



ANCULOSA MINOR, n. sp. PI. 1, figs. 7, 8. 



Shell small, depressed, thick, light olive in color, whorls five, those 

 of the spire flat ; periphery angulate or carinate; lines of growth fine 

 and cut by fine revolving impressed lines, giving the surface of the 

 shell a reticulate appearance under the microscope ; peristome 

 straight and thin ; aperture ovate, columellar callus thick, wide, dark 

 colored or white, extended across the parietal wall ; umbilical region 

 indented. Three specimens measured length 33, dium. 27, length, 

 30, cliam. 24, and length 30, diam. 25 hundredths of an inch. 



Habitat near Florence, Alabama, in the Tennessee river, near 

 the south bank, in a shaded situation where there was but little 

 current and a good many leaves in the water and on the bed of the 

 stream. A. A. H. Nov. 10, 1904. Cotypes in coll. Hinkley and 

 A. N. S. Phila. (No. 105866). 



This little species has been referred to Anculosa carinata, but I am 

 sure they are distinct ; compared with that species they are smaller, 

 thicker, spire not as elevated, aperture more regular oval and the 

 columellar callus thicker. From A. costata it differs in being more 

 elevated, thicker, whorls flat and suture linear, aperture smaller. 



The young of this species is very much like the young of A. crassa 

 Haldeman, but are more elevated, have no bands and the impressed 

 lines are more strongly marked ; nor does crassa have the second 

 carina. The young are quite close to those of A. praerosa and 

 tintinnabulum (see the Nautilus vol. 21, page 110, plate 10, figures
