Shell turbinate, varying in color from pale yellow to orange, with 

 the peristome a little paler than the rest. Nuclear whorls 2, well 

 rounded, microscopically granulose, with the last portion of the last 

 tiu'n sho\\dng the beginning of the postnuclear sculpture. Post- 

 nuclear whorls inflated, strongly rounded, marked by retractively 

 slanting, sublamellar axial riblets, of which 50 occur on the first, 70 

 on the second, and 82 on the last in the specimen figured. These 

 riblets form low, flattened cusps at the summit. On the last whorl 

 1, 2, or 3 intercalated riblets may be present between the coarser 

 ones, which are less than half the strength of the heavier ribs. Suture 

 strongly channeled. Periphery well rounded. Base short, openly 

 umbilicated, well rounded, marked by the continuation of the axial 

 riblets and by a poorly defined spiral cord a little posterior to the 

 umbilical angle. The axial riblets continue into the umbilicus, where 

 they become somewhat enfeebled and closely crowded. Here too 7 

 rather strong spiral cords arc present, of which the one forming the 

 outer margin of the umbihcus is the strongest. Aperture broadly 

 oval; peristome double, the outer flaringly expanded, adnate to the 

 preceding turn at the parietal wall; the inner also broadly expanded 

 and appressed to the outer, being differentiated from it at the posterior 

 angle and on the inner lip. Operculum typically annularid. 



The specimen described and figured, U.S.N.M. No. 11051, is one 

 collected by C. Wright at Baracoa, Oriente Province, the type 

 locality. It has 4.2 whorls and measures: Length, 8.2 mm.; greater 

 diameter, 9.3 mm.; lesser diameter, 7.5 mm. 



ANNULARIA (ANNULARELLA) VICTORIS, new species 



Plate 50, Figures 7-9 



Shell rather large, broadly turbinate, orange-red except for the 

 peristome, which is paler; the interior of the aperture is brilliant 

 orange immediately within the peristome, gradually becoming paler 

 inward, the tip being the most brilliant. Nuclear whorls 2, well 

 rounded, microscopically granulose, conforming wdth the outline of 

 the spire. Postnuclear whorls moderately strongly rounded, marked 

 by decidedly lamellose axial ribs, between which finer spiral threads 

 varying from 3 to 8 in number are present. These finer threads are 

 also slightly variable in size. On the first whorl the finer ribs are not 

 apparent, 41 of the heavier being present. The second whorl has 50
