Discussion. Luria cantaurana n. sp. is by far the 
largest Luria species of the Cantaure Formation. As 
can be seen from the shell formulae, it differs from L. 
fossula (shell formula; 43.0 (60.4 - 48.8) 22: 16) in 
having significantly fewer columellar teeth, whereas 
L. dominicensis (shell formula; 39.5 (59.4 -48.1) 30: 
25) has a similar number of columellar teeth, but a far 
greater number of labral teeth. The early Miocene L. 
dockeryi from the Chipola Formation of Florida 
cannot be separated from L. dominicensis on the basis 
ofthe shell formula (see below). 
Dolin (1991) synonymised Cypraea fossula 
Ingram, 1947 with Cypraea dominicensis Gabb, 1873. 
However, Cypraea fossula belongs within the genus 
Trôna (see below). Luria dominicensis (LT 36, CT 29, 
Pilsbry, 1922; shell formula 39.5 (58.7 - 48.1) 30: 24), 
from an unknown locality in the Dominican 
Republic). The species from the early Miocene 
Chipola Formation of Florida originally identified as 
Luria dominicensis by Dolin (1991) was renamed 
Luria (Tessellata) dockeryi Dolin & Lozouet, 2004. 
Luria dockeryi has numerous short teeth (LT 36, CT 
29, Dolin, 1991; shell formula 39.5 (59.4 - 48.1) 30: 
25). The shell formula is identical to that of the 
holotype of Luria dominicensis. Unfortunately the 
holotype (ANSP 3003) illustrated by Pilsbry (1922) 
cannot be located. Dolin & Lozouet (2004) renamed 
the Chipola species without mentioning how it 
differed from the Dominican taxon. There is little to 
distinguish the two, from the scant material available, 
and they may be synonyms. 
Jousseawnea joossi Schilder, 1939 (p. 23, fig. 23) 
was synonymised with Luria dominicensis by Dolin 
(1991). The holotype is an internai cast from the 
Miocene of Trinidad representing an indéterminable 
Luria sp., and it should be considered nomen dubium.
