 Cadulus phenax Pilsbry and Sharp, Proc. Acad. Nat. Sci. Phila., vol. 



49, p. 472, pi. 11, figs. 23, 24, 1897. 



We found hundreds of this delicate little shell in the bluffs 

 of the Mao River. C. dentali?ius is the Bowden analogue. 



Localities. — (Exp'd ' 16) Bluff 2 (comparatively scarce), Bluff 

 3 (very abundant), Cercado de Mao.

 Cadulus elegantissimus Pilsbry and Sharp, Proc. Acad. Nat. Sci. Phila., 



vol. 49, p. 473, pi. 11, figs. 28-30, 1897. 



We collected over fifty shells of this species which resembles 

 C. phenax but is nearly twice as large. The two occur together 

 in the same bluffs. 



Localities. — (Exp'd '16) Bluff 2 (comparatively scarce), 

 Bluff 3, (common), Cercado de Mao; Zone H, Rio Cana at 

 Caimito. 



Cadulus denticulus-tigris ', n. sp. 

 Plate 26, Figure 7 



Shell small, polished, smooth, shaped precisely like a minia- 

 ture tiger's canine tooth; greatest diameter sub-central, thence 

 tapering towards either extremity; apex minute circular; aper- 

 ture somewhat larger, sub-circular. Length of shell 6.25, great- 

 est diameter 1.75 mm. 



A very rare species, quite different from any fossil Cadulus 

 described from Santo Domingo or Bowden. 



Locality. — (Exp'd '16) Zone G, Rio Gurabo at Los Que- 

 mados.
