Tliis, the typical subspecies, comes from Jiguani, Oriente Province. 

 It differs from A. (T.) jiguanensis negrosensis in being miicli paler and 

 from A. (T.) jiguanensis bairensis in having the axial riblets more 

 slender and less strongly developed, and in having the peristome 

 rayed. 



The specimen described and figured, U.S.N.M. No. 355882, is one 

 of five listed under that number. It has a little more than 4 whorls 

 remaining and measures: Length, 13.9 mm.; greater diameter, 7.3 

 mm.; lesser diameter, 5.6 mm. 



ANNULARIA (TROSCHELVINDEX) JIGUANENSIS NEGROSENSIS, new subspecies 



Plate 37, Figure 8 



This subspecies comes from Alto de los Negros, Sierra Maestra 

 Oriente Province. It agrees with the typical race in having the peri- 

 stome rayed, but it has tlie axial ribs much stronger and the last 

 whorl not solute, but adnate, to the preceding turn. The whole 

 color scheme presents a marbled effect, and there are decided axial, 

 almost zigzag, fulgurations of darker brown than the general colora- 

 tion. There is also a mottling of flesh color, and the denticles at 

 the summit are white. 



The type, U.S.N.M. No. 535546, has 4.9 whorls remaining and 

 measures: Length, 14.3 mm.; greater diameter, 7.0 mm.; lesser 

 diameter, 5.5 mm. 



ANNULARIA (TROSCHELVINDEX) JIGUANENSIS BAIRENSIS. new subspecies 



Plate 37, Figure 9 



This subspecies comes from Baire, southeast of Jiguani, Oriente 

 Provmce. It has the last whorl adnate, m which respect it agrees 

 with A. (T.) jiguanensis negrosensis, but it has the ribs a little more 

 strongly developed and it lacks the radiating rays on the outer peri- 

 stome. The color scheme approximates that of the typical race, 

 but it is a little darker. 



The type, U.S.N.M. No. 535548, has almost 5 whorls remaining 

 and measures: Length, 14.7 mm.; greater diameter, 7.0 mm.; lesser 

 diameter, 5.9 mm.
