Pease was probably wrong in his interpretation of Pfeif- 

 fer 's diagnosis, as shells which I have carefully compared 

 with the original lot in the British Museum are all from 

 Oahu, and from the characters of the types I have no doubt 

 that they also were from this island. 



The shells from Waialae agree very closely with the types, 

 except that they have one-half of a whorl less. 



L. pyramis is somewhat related to glutinosa Pfeiffer. The 

 spire is, however, much longer. Some of the shells from 

 Nuuanu have a faint darK brown band encircling the peri- 

 phery.

The shell is minutely perforate (sometimes imperf orate) , 

 broadly ovate, brownish corneous, glossy, subdiaphanous, near 

 the suture slightly irregularly striate, the rest nearly smooth, 

 under a lens minutely striate with lines of growth. Spire 

 broadly conic with slightly convex outlines, apex obtuse, pale 

 corneous. Suture scarcely impressed, faintly margined with 

 a darker band, slightly crenulate. Whorls 5%, slightly con- 

 vex, the first 3 closely coiled and increasing slowly, the rest 

 increasing more rapidly, the last large, tumid, tapering to 

 the base. Aperture large, slightly more than one-half the 

 length of the shell, obliquely truncate-ovate, very slightly 

 oblique, perpendicular, slightly contracted above and ascend-
