ANNULARIA (EUTUDORA) CABRERAI. new species 



Plate 33, Figure 1 



Shell very broadly turbinate, almost helicoid, very widely openly 

 umbilicated, flesh colored, with interrupted spiral bands of brown. 

 The dots composing these bands are also arranged in axial series. 

 Peristome white. Nuclear whorls 2, strongly rounded, microscopi- 

 cally granulose. The postnuclear whorls are marked by very strong 

 spiral cords, of which 6 are present on the first and second whorls. 

 On the last whorl there is an intercallated cord a little weaker than 

 the heavier ones between each of the stronger, thus totaling 12 between 

 the summit and the periphery. These cords are much narrower than 

 the spaces that separate them. The axial sculpture consists of rather 

 distantly spaced, feeble, threadlike riblets. Base short, strongly 

 rounded, broadly openly umbilicated, marked by 7 spiral cords, which 

 are of the same strength and spacing as those on the spire. The 

 umbilical wall bears 13 additional spiral cords, which are rendered 

 crenulated by the well marked, slender axial riblets. The last whorl 

 is solute for about one-tenth of a turn. Aperture broadly oval; peri- 

 stome double, the inner expanded and reflected and appressed to the 

 outer; the outer is rather broadly expanded, a little wider on the 

 anterior half of the columella, expanded into an auricle at the sum- 

 mit, and slightly fluted. A breathing pore is usually present on the 

 parietal wall a little anterior to the posterior angle; sometunes this is 

 absent. Operculum typically eutudorid. 



The type, U.S.N.M. No. 356378, comes from Portugalete, near 

 Cuatro Caminos, Habana Province. It has 5.5 whorls and measures: 

 Length, 12.5 mm.; greater diameter, 12.5 mm.; lesser diameter, 9.0 

 mm, 



ANNULARIA (EUTUDORA) LIMBIFERA ([Menke] Pfeiffer) 



Shell almost trochid in shape, of flesh-colored, yellow, or pale brown 

 ground color, marked by interrupted spiral series of brown spots; 

 the peristome varies in color from white to soiled yellow; the interior 

 of the aperture varies from flesh color to pale orange, usually showing 

 the external color markings within. The entire surface has a dull 

 waxy luster. Nuclear whorls 2, well rounded, microscopically granu- 

 lose, except for the last portion of the last whorl, which shows the 

 beginning of the postnuclear sculpture. Postnuclear whorls strongly
