convex, but tapers slightly toward the base. The aperture is 

 slightly oblique, bluish- white inside. Peristome white; outer

 curved posterior part, Where it is thin. Columellar margin 

 dilated, biramose above, having a low weak nodule just be- 

 low the middle, at the termination of the internal callus. 



Length 17, diam. 9.5, aperture 9.3 x 6 mm. 



Habitat unknown (no. 4237 coll. Carnegie Mus.).

In shape and sculpture this species resembles Partula re- 

 gularis, but it differs by the very distinctly marginated suture, 

 the less approaching terminations of the lip, the better de- 

 veloped callus within the lip, and the coloration, which seems 

 to be quite characteristic. It will probably be found to be 

 .a species of the Solomon Island or the New Hebrides. 



This species was in the Hartman collection under the name 

 "P. laevigata Pfr.," but on the label Dr. Hartman expressed 

 the opinion that it was not that species. It has*little in com- 

 mon with l&vigata, which evidently belongs to a wholly dif- 

 ferent group. Named in honor of Dr. J. W. Holland, Director 

 of the Oarnegie Museum.
