GLESSULA. 381 



Beddome considered this species probably an immature form of 

 tenuispira, and Pilsbry regards it as a variety. The more flattened 

 whorls and the acuminate upper portion of the spire, however, 

 appear to me to warrant its being accorded specific rank.

Beddome states that full-grown specimens were very rarely 

 found by him, " though young, halt'-, and three-quarter-grown 

 ones are most abundant on the Nilgiris. This and some other 

 species certainly breed before the shell attains full size or a 

 hardened peristome, as I have taken eggs from such shells. The 

 peristorne differs much in mature specimens, sometimes being 

 very thick and solid, sometimes quite thin, but, even then, firm 

 and not breaking or becoming jagged at the least touch, which is 

 the sign that the shell has not finished its growth. Full-grown 

 examples of shiplayi are very like tenuispira, but smaller. The 

 species is, in fact, intermediate between the latter and baculina, 

 but the whorls are more convex and increase more suddenly than 

 is the case in either of the other two species. It also runs 

 nilayirica very closely, but the latter has a stronger sculpture, and 

 is broader at the base."
