antr. 7|, convexi, ultimas f longitudinis subaequaus, basi rotund-

 apertura verticalis, subtriangulari-seniiovalis ; perist. simplex, 

 margine dextro regulariter arcuato.

Is stated by Pfeiffer to diifer from liis H. ceylanica in having 

 a smoother, more glossy shell with longer spire, shorter last 

 whorl, and in the columella being more arched forward. His 

 figure of ceylanica in Conch.-Cab., however, has the last Mhorl 

 actually less high than jjunctor/allana. Beddome was unable 

 satisfactorily to distinguish it from ceylanica, except that the 

 latter is generally larger. Pilsbry, on the other hand, reduces 

 punctogallana to varietal rank under G. niteas. He figures a shell 

 received as ceylanica (pi. 6, fig. 5) which he refers to punctoyallcma, 

 but it appears to pertain rather to nitens, which has a con- 

 siderably more elongated spire than the former. 



After examining considerable series of both I find they may be 

 readily separated by the character of the columella, which is 

 decidedly shorter in the present species, which, moreover, has the 

 base more contracted, and the whorls more closely coiled. Most 

 of the specimens I have seen labelled ceylanica pertain to puncto- 

 (jallana.
