1886.] NATURAL SCTEisrcfeS OF PHILAbiELPHTA* 35 



Hah. Island of Salisbaboe^ one of the Falow Inlands, between 

 Gilolo and Mindanao. 



Obs. I received this shell from Mr. Layard, through Mr. A. 

 Garrett ; in outline and general appearance it resembles some 

 varieties of P. varia. I have named it in honor of Dr. Wesley 

 Newcomb, one of our oldest American conchologists, well known 

 for his writings on the allied genus Achatinella of the Sandwich 

 Islands. 



P. eximia, nobis. Plate II, fig. 14. 



Shell dextral, ovate, elongate, solid ; spire elongate, half the 

 length ; body - whorl large, sutures well impressed ; whorls 

 rounded, oblique lines fine, .and decussated by almost obsolete 

 spiral striae ; umbilicus slightly compressed ; aperture direct, 

 oval ; lip white, moderately reflected and flat ; columella wide 

 above ; margins of the peritreme connected by a thin deposit. 

 Color of the epidermis a soiled pale green, when separated 

 leaving the shell white. Length 23 mill., width 11 mill. ; length 

 of aperture 11 mill., width 5 mill. 



Hab. Aneiteum Island^ New Hebrides. 



Obs. I received one example of this fine species from Mr. 

 Layard, through Mr. Jno. H. Thomson. 



Partula rufa, Less. Plate II, fig. 15. 



Partula concinna, Pease. Plate II, fig. 16. 



Partula pellucida, Pse. Plate II, fig. 17.

Partula (Diplomorpha) De la Touri, nobis, Plate II, fig. 19. 



Shell dexti'al, solid, short conic ; whorls 4|^, rounded, suture 

 deep, body-whorl inflated, almost two-thirds the length, surface 

 with coarse oblique strife, umbilicus wide, aperture perpendicular, 

 lip white, moderatel}' reflected and revolute, the external margin 

 slightly indented, encroaching on the aperture ; color of the 

 epidermis light brown, color of the aperture dark orange. Length 

 20, diameter 14 ; length of aperture 12, diameter 8 mill. 



Hab. Au7^a Island, in the Halo Bass, Santo Espirito Group. 



Obs This shell has recently been discovered by Mons. De la 

 Tour, an enthusiastic young naturalist, who writes that this little 

 island teems with molluscan life. But one other species is known ; 

 P. {Diplomorpha) Layardii, Brazier, herein figured. It is found 

 at Yate or Sandwich Island, New Hebrides. The habits of the 

 animals are terrestrial.
