 acute ; fulvous, with a chestnut line on the periphery and suture;

Singapore. 

 P. BRUNNEA, A. Ad. PL 73, figs. 9, 8. 



Solid, narrow, yellowish brown; whorls 15, flatly convex, 

 aperture ribbed within. Length, 15 mill. 



Japan. 



This species is figured twice in the Conch. Iconica, first under 

 the above name, and again as P. fulva, Sowb. (fig. 8), with 

 brunnea, A. Ad., as a synonym ; Mr. Sowerby being under the 

 impression that his figures represent different species, and that 

 Mr. Adams had described them both as brunnea, whereas the 

 latter only described brunnea once. 



P. ATTENUATA, A. Ad. PI. 73, fig. 5. 



Slender, whitish, shining, finely spirally striated ; whorls flat- 

 tened, suture profound. Length, 1T5 mill. 



Ins. Bohol, Philippines. 

 P. ADAMSI, Tryon. PI. 73, fig. C. 



Subulate, polished, smooth, orange-brown ; whorls numerous, 

 flatly convex, suture deep; lip lirate within. Length, 10'5 mill. 



Ins. Bohol, Philippines. 



For Obeliscus aclis, A. Ad. Preoccupied by himself in section 

 Mormula. 



P. ACTCULATA, A. Ad. PI. 73, figs. 10, 11. 



Slender, fulvous white ; whorls numerous, convex, flattened in 

 the middle, longitudinally substriate, suture deep. 



Length, 12'5 mill. 



Ins. Cagayan, Philippines (Cuming); Viti Is. (Garrett). 



Described as an Obeliscus, and afterw.ards placed in Syrnola. 

 Sowerby, who includes both in his Pyramidella, apparently 

 supposes them to be distinct species, and changes the name of 

 the one to P. denticulata (fig. 11). If his much enlarged figure 

 is accurate, this is probably a distinct species.
