axials consist of growth-lines only, variable in strength, arcuate between 
keel and suture above. Aperture small, ovate, produced into a long canal ; 
outer lip angled at keel, thence concave followed by a convexity, and 
beneath this rapidly narrowing to canal; columella narrowly callused, 
straight in middle portion, narrowing and slightly twisted to left.

Suter included these specimens with his Leucosyrinz alta subsp. tran- 
senna. Fortunately, the type of Suter's variety is in a separate tube from 
other specimens. In his description he remarks on the absence of axial 
riblets, but failed to note the difference in the spiral sculpture, the keel, 
and the aperture. 
Columbarium maorum n. sp. (Plate 13, fig. 2.) 
The only specimen has the anterior canal broken off. Shell small, spire 
narrowly produced, pagodaform, the last somewhat abruptly contracted at 
base. Whorls seven or eight, a serrated prominent carina below middle, 
and below; on base of last whorl are five spiral cords, diminishing in size 
anteriorly, minutely granulate, narrower than grooves, the two upper cords 
distant and strongest, the grooves with one or two minute threads ; axial 
sculpture consists of fine growth-lines, more pronounced on base.  Proto-
