intersections. The base is marked like the spire, but in the um- 

 bihcus the axial sculpture becomes reduced and the spiral intensified. 

 Aperture broadly oval, showing the external color markings within. 

 Peristome double, the outer moderately broadly expanded and some- 

 what wavy, the inner but slightly expanded, reflected over and 

 appressed to the outer. They both carry the color markings of the 

 outer surface. The operculum is typical Tudorid. 



Type and thirteen specimens. — Cat. No. 218044, U. S. N. M., were 

 collected by Dr. W. L. Abbott at Trou de Bon Dieu, Port de Paix, 

 Haiti. The type measiu-es: Length, 14.8 mm.; major diameter, 

 7.8 mm.; minor diameter, 6.8 mm.: altitude of aperture, 6 mm.; 

 width of aperture, 5 mm. 



EUTUDORA (EUTUDOROPS) AZUCARENSIS, new speclcB. 



The shell is ovate, pale brown, early whorls decollated. The tliree 

 and a half remaining in the type are crossed by numerous sublamellar 

 axial riblets wiiich are decidedly expanded at the summit, where tliey 

 project conspicuously above the suture. These riblets are separated 

 by spaces about as wide as the riblets ; on the early whorls, however, 

 there are irregular interruptions in the even spacing of them so that 

 smooth spaces occur in places between the lamella. There are five 

 broad, low, rounded spiral cords, the first of which is about three 

 times as far from the summit as it is from its neighbor. The spiral 

 cords render the axial riblets slightly tuberculated and wavy at their 

 intersections. Base well rounded, marked by five spiral cords which 

 increase regularly in strength from the periphery to the umbilicus. 

 These cords render the axial riblets, which extend to the umbilicus, 

 wavy and slightly nodulose. Aperture subcii'cular; outer peristome 

 broadly expanded, notched on the upper lip and bent inward to seal 

 the umbilicus, covering the parietal wall with a broad callus. Inner 

 peristome reflected over and almost fused with the outer. A breath- 

 ing-pore pimctures the parietal wall a little behind the peristome at 

 the posterior angle of the aperture. 



Operculum typicallj^ Tudorid. 



Type and ten specimens. — Cat. No. 314943, U. S. N. M., were

The type measm-es : Length, 7 mm. ; greater diameter, 7 mm. ; lesser 

 diameter, 6.2 mm.; length of aperture, 5 mm.; width of aperture 

 5 mm.
