This subspecies comes from the shore Une of the Rio San Diego, from 

 which we have specimens from the Portales de Galalon to Catahna. 



The specimen figured, U.S.N.M. No. 11016, a topotype, has 3.5 

 whorls remaining and measures: Length, 11.2 mm.; greater diameter, 

 7.9 mm.; lesser diameter, 6.2 mm. It was collected by Wright at the 

 foot of the Sierra La Giiira; it has 102 riblets on the first turn, 170 

 on the second, and 238 on the last. These riblets, which are much 

 stronger than those of A. (A.) sauvallei chorrerensis, are also rendered 

 slightly sinuous by the spiral sculpture. 



Gundlach states of the animal: "Gathered at the foot of the Sierra 

 de Giiira on large rocks in the forest. Anunal bright gray with faint 

 olive sheen. White dots are present on the rugosities of the foot and 

 between the antennae and a black one upon the forehead. Tentacles 

 coral red with blackish tip. The mass of the body where it emerges 

 from the shell is of a dark olive coloration." 



ANNULARIA (ANNULAROPS) SAUVALLEI CHORRERENSIS, new subspecies 



Plate 30, Figure 1 



This subspecies was collected by Arango in the Sierra de la Chorrera. 

 It differs from the other white members in having the axial ribs exceed- 

 ingly fine, slender, and closely spaced. The spiral sculpture is quite 

 obsolete, and it renders the axial riblets slightly wavy. 



The type, U.S.N.M. No. 356158, has 108 riblets on the first of the 

 remaining turns, 116 on the second, and 184 on the last. It has 

 almost 4 whorls remaining and measures: Length, 9.7 mm.; greater 

 diameter, 6.8 mm.; lesser diameter, 5.6 mm. 



ANNULARIA (ANNULAROPS) SAUVALLEI NATENSONI, new subspecies 



Plate 30, Figure 3 



This race was collected by Natenson at La Cantera, Consolaci6n del 

 Sur. It is easily distinguished from the others by the fact that the 

 entire shell, as well as the peristome, is pale orange. The axial ribs 

 and the spiral sculpture are stouter, also. 



The type, U.S.N.M. No. 493454, has 4.2 whorls remammg and 

 measures: Length, 13.2 mm.; greater diameter, 7.8 mm.; lesser diam- 

 eter, 6.2 mm.
