Description. See C.B. Adams (1845) and Clench & 
Turner (1950). The protoconch has a diameter of 
about 400 pm, with about 2.25 whorls; the First part 
(about 1.75 whorls) is smooth but immediately small 
ribs begin in the suture and are complété on the last 
half whorl. 
The colour is white or cream, sometimes with two 
brown lines in the middle of the last whorl (Fig. 10A). 
Dimensions: Up to 5 mm in length. 
Distribution. Throughout the Caribbean. Some 
references can not be included due to doubtful 
détermination of the species. 
Remarks. This is the older species in this group 
described trom the Caribbean. The First problem is its 
generic placement. In a recent work by Fernândez- 
Garcés & Rolân (2010) this species was referred to the 
genus Pyrgocythara Woodring, 1928. However this is 
open to discussion, as no more information on soft 
parts is availabié. In the présent work we hâve decided 
to place it provisionally in Agathotoma, following 
most authors and databases. 
We hâve had many doubts about the assignment of A. 
candidissima made by several authors, as for example 
Leal (1991: pl. 24A), and also Garcia (2008: fig. 23) 
who reproduced the figure of the previous author. 
These Figures presented a shell with the upper extreme 
of the axial ribs very prominent which is not in 
accordance with the figure of the type represented in 
Clench & Turner (1950); on the contrary these shells 
are more coincident with the morphology of the 
species we will mention below as A. castellata. 
Pyrgocythara coxi Fargo, 1953 appears in Williams 
(2006) as a synonym of A. candidissima. We think 
that it is not, as the holotype of A. coxi shows axial 
ribs narrower than those on the typical A. 
candidissima. 
In De Jong & Coomans (1988: Figure 604A, p. 264) 
the shell presented as A. candidissima is not this 
species and the shell Figured in Fig. 604B is also 
dubious. 
The shell Figured here (Figures IA, 10A) has the 
typical profile. 
The species is correctly represented on some internet 
sites - (Conchologist Forum and Fémorale, for 
example).

Description. See Garcia (2008). In the original 
description the protoconch is mentioned as having 1.5 
whorls, but following the Verduin method (Verduin, 
1976) which we usually employ, it has only a little 
46
