32 PROCEEDINGS OP THE ACADEMY OF [1886. 



Color a soiled white, apex rufous. Length 16 mill., diameter 

 8 mill. ; length of aperture 6 mill., diameter 3^ mill. 



Hab. Erromango Island, Solomon Islands. 



Obs. I possess two examples of this species from Dr. Cox, of 

 Sydney, Australia. They were collected by Dr. Turner at the 

 above island ; it differs from Carteriensis especially in the 

 margins of the peritreme approximating more closely than in 

 that species. 



P. corneola, nobis. Plate II, fig. 6. 



Shell dextral, ovate conic, smooth and polished, corneous, 

 translucent; whorls 5, slightly rounded, spire half the length, 

 spiral striae numerous, waved and very fine, umbilicus compressed, 

 aperture ovate, with a rounded pillar tooth, and a small tubercle 

 on the columella, lip thick, white, and almost flat, with the 

 margins connected by a callus. Color pale horn, with the apex 

 pale rufous. Length 17^ mill., diameter 9 mill. ; length of 

 aperture 7 mill., diameter 4 mill. Smaller example : Length, 

 16 mill. ; diameter, 8 mill. 



Eab. Eimeo, Morea? (Mr. Geale). 



Obs. Several years ago I obtained two examples from Mr. 

 Geale, who accompanied Hugh Cuming. This shell is not found 

 in the British Museum, or the Jardin des Plantes, and I have 

 only met with it twice in private collections. It differs from all 

 the Marquesas species with which I am acquainted, and it pos- 

 sesses the dome-like apex of the Solomon Island group. 



P. Coxi, Angas MS. Plate II, fig. 7. 



Shell dextral ovate, slightly elongate, thin and translucent 

 whorls 5, rounded, suture impressed, oblique lines of growth fine 

 and sparsely decussated by waved spiral striae ; aperture ovate 

 direct, umbilicus compressed, lip reflected, white and concave 

 color 3'ellowish white; apex slightly rufous. Length 15 mill, 

 diameter 7 mill.; length of aperture 5 mill., diameter 3 mill. 



Hab. Ysabel Island, Solomon Islands (Capt. Brazier). 



Obs. This shell was collected at the above locality by Captain 

 Brazier, and he has kindly given me a number of examples. In 

 1867, Dr. Cox sent me examples of P. pellucida, Pse., for Coxi. 

 These were pronounced micans, Pfr., at the British Museum, 

 causing the error in my Bibliographical Catalogue. F. micans 

 is a much larger shell.
