APPENDIX TO PUPILLIDAE. 63 



accompanied by a short infraparietal lamella, about as figured 

 for S. huhhardi in pi. 8, fig. 3. These lamellae have no nodes 

 or knots, but there is a weak microscopic roughening of the 

 edge about as described for Discostroljilops on page 47. I 

 could not get the objective near enough to determine the exact 

 structure without breaking the whole base. Height 1.7 mm., 

 diam. 2.9 mm., umbilicus 0.75 mm. 



The James Island specimen (PI. 16, figs. 2, 2a) is fully- 

 mature and opaque. It also is striate basally, but the striae 

 in part are somewhat thread-like, with ribs within the 

 umbilicus and a few near the lip. The expanded lip has a 

 white thickening. There is no little fold between the second 

 and outer basal folds. The parietal lamella, as in the Nar- 

 borough shell, does not penetrate more than a third of a turn. 

 The infraparietal reaches weakly almost to the aperture. 

 Height 1.9, diam. 2.9 mm. 



There appear to be some small differences in form and 

 sculpture between the shells from different islands, but until 

 longer series are at hand for comparison it is not certain that 

 they have racial significance.

Vol. 24, p. 8. The status of Leucochilus Boettger (1881, 

 type Pupa armifera Say) was left uncertain in the place cited. 

 This case has now been considered by the International Com- 

 mission on Nomenclature in Opinion 115, and the following 

 conclusion reached. 



' ' The Commission herewith suppresses Leucochilus, 1881, in 

 favor of LeucocMla, 1860. Any other course would involve 

 risk of lasting and constant confusion in two rather closely 

 allied genera."
