The holotype is in the Museum of Comparative Zoology no. 32455, andparatype no. 47830 from Auki. Malaita.Re mar k s. This species has nearly lost the carina and it is only slightly indicatedon a few specimens in the type series. There is as well a than lamina produced alongthe columella which parallels the face of the aperture. This ends smoothly on thebasal area of the lip. Spire forms an angle of 112°. Aperture cast at an angle of 39°with a horizontal base line.Notes: Animal white, found on bushes in forest (EYERDAM).Crystallopsis (CrystaUopsis) lactiOo. (Pfr.)Helix lactiflua PFEIFFER 1861, Proc.

SoUVERBIE'S species, isabellensis. seems to be C. lactiflua Pfr. withoutquestion. It is possible that either of the above localities may be wrong; more probablythat of PFEIFFER'S as his species was based on Cumingian material, long Doted forerrors in assignment of proper locality.184
