Shell broadly conic, almost turbinate, flesh colored with inter- 

 rupted spiral bands of brown. Nuclear whorls almost 2, well rounded, 

 microscopically granulose, except for the last portion of the last turn, 

 which shows the beginning of the postnuclear sculpture. Postnuclear 

 whorls strongly inflated, strongly rounded, marked by feeble incre- 

 mental lines and by strong spiral threads, of which 8 occur on the first 

 whorl, 9 on the second, 14 on the third, and 15 on the last between the 

 summit and suture; the addition of the spiral threads always begins 

 in an inconspicuous manner, and as the shell increases the threads 

 increase in size. The spiral thread at the summit is feebly crenu- 

 lated, and some of the others show mere indications of minute nodules. 

 Suture strongly constricted. Periphery inflated, strongly rounded. 

 Base inflated, strongly rounded, narrowly, openly umbilicated, marked 

 by 11 spiral threads and by incremental lines; the latter render the 

 summit of the spiral threads feebly nodulose. The umbilical wall is 

 marked by the continuation of the axial riblets and by 18 spiral 

 threads, the junction of the two rendering the spiral threads serrated. 

 Aperture broadly oval; peristome simple, broadly expanded, notched 

 on the parietal wall near the posterior angle to fit the preceding turn, 

 to which it is adnate, and to leave a breathing space when the opercu- 

 lum is withdrawn. Operculum typically annularid. 



The specimen described and figured, U.S.N.M. No. 356369, is a 

 cotype collected by Arango at the ancient Ingenio San Luis, Jaruco, 

 Ilabana Province. It has 5.7 whorls and measm-es: Length, 16.9 

 mm.; greater diameter, 14.6 mm.; lesser diameter, 9.9 mm. 



This species seems to range through the surroundmg hills extending 

 from a little west of Tapaste to Jaruco. 



The animal of this species was collected by Bartsch on July 28, 

 1928. He describes it as follows: Animal short, upper surface darker 

 than the rest, marked by numerous white dots. A ring about the 

 base of the tentacles is almost white. There is a short pinkish streak 

 immediately behind this ; sides of body smoke gray with a bluish tinge, 

 a little paler than the dorsum. Tentacles white at base, the rest 

 orange tipped with brownish buff. Sole of the foot same color as the 

 sides. The animal when at rest suspends itself by a mucous thread.
