outward to parallel the plate and overlapping to form a flat surface, 

 thus forming a double operculum with a deep groove around its 



margin. 



Type.— A female specimen, Cat. No. 314964, U.S.N.M., was 

 collected by Torre and Sifontes at Santa Cruz Mountains, on the 

 right bank of the River Maximus, opposite Los Cangilones, in the 

 Province of Camaguey, Cuba. It measures: Length, 10.8 mm.; 

 greater diameter, 6 mm.; lesser diameter, 5.25 mm.; length of aper- 

 ture within, 3.25 mm.; width of aperture within, 3 mm. A male 

 specimen from the same lot, with tip present, measures: Length, 10 

 mm.; greater diameter, 5.1 mm.; lesser diameter, 4.75 mm. 



This species, which bears a strong resemblance through, all its shell 

 characters to the numerous species herein described from the same 

 region, must nevertheless be placed in the genus Eutudora by reason 

 of its operculum, which is typical of that genus. It falls naturally 

 into the group of Eutudora torquatum of the subgenus Eutudorops, 

 by reason of its sculptural characters.
