vni, a, 4 Smith: Fossil Invertebrate Fauna 261 



A perfect specimen with beautiful proportions. Possibly 

 slightly larger than the Javan forms. This was compared with 

 Martin's figures, and not with the actual specimens as in most 

 cases. 



Locality: Bani, Pangasinan, Luzon, No. 758. 



Formation: Pliocene (?) marl. 



Elevation: 50 (?) meters. 



Tunis ( ?) agusana sp. nov. Plate III, fig. 6. 



This is a clean, white shell possessing almost its original 

 polish, but with no trace of color. The aperture is not perfect 

 so that it is difficult to place it exactly. I can find nothing quite 

 like it either in the Quadras collection or in the literature. 

 Although there is little trace of the byssal notch left, there is 

 a shallow groove just below the suture which may represent it. 

 The shell is 45 millimeters high and 17 millimeters wide, and 

 its spire is sharply acuminate making an angle of 27°. Follow- 

 ing the whorls are well-marked grooves about 1 millimeter 

 apart, and between these are very fine cross striations. The 

 sides of the whorls are flat. 



Locality: Agusan River, Mindanao, No. 1054. 



Formation: Recent or Pleistocene shale. 



Elevation : About 50 meters.

NASSA Martini 



Shell ovate, inflated ; aperture with short, reverted canal ; inner 

 lip callous, expanded, outer margin usually crenate internally. 



Sparse in upper Cretaceous and Eocene ; abundant in Miocene 

 and Pliocene. Over 200 living species. (Zittel.) This is a 

 worldwide genus in tropical seas. 



Fossil species of Nassa in the Philippines.

This is quite the same as Cuming's specimens of a recent 

 form from the Philippines with which I compared it directly. 

 It also resembles N. dertonensis Bell. 23
