104 PLACOSTYLUS, FIJI IS. 



Alt. 70, diam. 25 ; aperture with peristome 36 mill. 



Alt. 62, diam. 25 ; aperture with peristome 35 mill. 



Habitat unknown. 



Much more slender than P. elobatus, with coarser corrugation, 

 entirely different coloration and very narrowly reflexed lip. It 

 lacks the internal callous fold of P. paeteli, which is a species of 

 stouter contour. The general aspect of the shell inclines me to 

 believe it from the Viti group. 



P. GRAEFFEI (Crosse). PI. 43, fig. 6. 



" About the same size as elobatvs, but is much less rugose, the 

 base less produced, and is of a yellowish-olive color with a bluish- 

 white aperture. 



" About the same size and shape as P. elobatus, but is a smoother 

 shell, and the color of my two specimens is olivaceous without any 

 markings. The aperture is whitish, and the columellar fold is more 

 horizontal than in the latter species" (Garrett). 



Viti Levu, in the central portion at Vuni-Vatu (Dr. Graeffe).

This species has not been formally defined, but is know r n by Gar- 

 rett's descriptive notes and Crosse's figure. The name Placostylus 

 moussoni Graeffe in Schmeltz, is prior to graeffei, and not preoccupied, 

 but was absolutely without definition, and so far as the record goes, 

 was based upon P. elobatus of Mousson. It would really be a 

 synonym of elobatus, for Mousson did not call the present species 

 elobatus, but colubrinus, previous citations having been erroneous on 

 this point. Crosse, in 1875, supplies a figure, and uses the name 

 Bulimus moussoni, which was preoccupied by Pfeiffer ; but he pro- 

 poses B. grceffei as a substitute. This name has properly been 

 accepted by Pfeiffer and Garrett.
