THE NAUTILUS. 27 



portion of the Archipelago, but is not on the maps accessible to me. 



Mr. Crosse, in his recent paper on the New Caledonia laud and 

 freshwater shells published in the "Journal de Conchyliologie," 

 said that " Helix " singularis and its allies, represent in that fauna 

 the New Hebrides Diplomorpha, but I fail to detect so great an 

 analogy. It is right to observe, by the by, that singularis is really 

 found on Aneitum, one of the New Hebrides ; Mr. E. L. Layard 

 sent me two specimens from there, much smaller than any one I 

 ever saw from New Caledonia, but otherwise quite the same. I 

 must add that the true Pseudopartula (type Helixgalericulum^'Lous- 

 son), has nothing to do with this Melanesiau group, and are 

 evidently related to Amphidromus. Montrouzier's name Drapar- 

 naudia should be applied to singularis and sinistrorsa. The affini- 

 ties of the genus are difficult to state until the soft parts are ex- 

 amined. 



I avail myself of the opportunity of adding three species to the 

 list of New Caledonian species of Mr. Crosse who certainly over- 

 looked them, viz., Helicina nehoueensis, bourailensis and saxoniana, 

 all of Hartman. 



A NEW CANCELLARIA FROM THE ALABAMA EOCENE. 



BY T. H. ALDRICH. 



Cancellaria lanceolata n. sp. 



Shell elongated, whorls seven, first three nuclear and smooth, the 



others cancellated and having three strong revolving lines, the mid- 

 dle one much the larger, the costse numerous and fine. 

 Whorls are shouldered, suture deeply marked; body 

 whorl with seven or eight revolving raised lines. Aper- 

 ture oblong, outer lip serrated by the raised lines, nearly 

 smooth within. Columella lip without callus, bearing 

 two or more folds, part of the raised lines passing into 

 the aperture to form them ; canal short, oblique, slightly 

 twisted, no umbilicus. Length 7J, diam. 3f mm. 

 Locality. Choctaw Corner, Ala. Woods Bluff horizon. 

 This little shell has some resemblance to C. pulcherima H. C. 



Lea, but Mr. C. W. Johnson, of the Wagner Free Institute of 



Science, has compared the two and finds the above distinct. The
