New records and new species of Agathotoma 
more than one whorl and does not reach 1.25 whorls. 
Also Garcia (2008) did not mention the dimensions of 
the protoconch, which we calculate to be between 320 
to 340 pm in the figures. The protoconchs of our 
material are approximately 350-370 pin in diameter. 
Distribution. In Garcia (2008) it is recorded from: 
Bahamas, Belize, British Virgin Islands, Colombia. 
This is the first record for Cuban, Nicaraguan and 
Mexican waters. 
Remarks. Most of our material is consistently smaller 
than the shell figured by Garcia (2008), but the 
microsculpture of the protoconch and the teleoconch 
seems to be similar. 
We show the microsculpture with better detail (Figs. 
2F-G). 
A . candidissima is more elongate, less robust, the 
shoulder is rounded and not so angular, and the 
protoconch has almost 2.25 whorls.

Type material. Holotype in ANSP (416415) 
(represented in the original description). 
Type locality. Bahia de Campeche, SW Gulf of 
Mexico.

Description. See Garcia (2008). The protoconch is 
mentioned in the original description as having 1.25 
whorls, which agréés with our shells. In that work the 
dimensions of the protoconch were not mentioned, 
which we calculate to be about 470 pm in the figures. 
The protoconchs of our material are approximately 
400-430 pm in diameter. Otherwise, the 
microsculpture seems to be similar, although the 
zigzag Unes are not as well-defined as in our shells. 
The microsculpture of the teleoconch is shown in our 
plates. 
Distribution. In the original description, Garcia 
(2008) records this species from the southwestem 
Gulf ol Mexico, the southeast coast of Florida and 
south of Belize. This is the first record for Cuban 
waters. 
Remarks. In spite of the différences in the size of the 
protoconch and the microsculpture, we consider our 
material to be the same species. The shells are very 
similar to the type species of the genus, Agathotoma 
angusta (Jan) Bellardi, 1848 represented in Powell 
(1966: pl. 15, fig. 15), being even more similar to the 
type species than the shells of Agathotoma 
candidissima. 
We figure with better detail the microsculpture of both 
the protoconch and the teleoconch in Figures 3E-F. 
The species presented above are very different in 
profile and microsculpture, also with protoconch 
différences. The most similar protoconch is that of 
Agathotoma ecthymata but the microsculpture has 
minute tubercles aligned spirally.

Type material. The lectotype of A. castellata is in 
BMNH (1854.6.30.136-7) and was designated by 
Kilburn (1993: fig. 71); also it was represented by 
KAICHER (1984), as Agathotoma costellata (sic), and 
in Williams (2006). 
Type locality. Unknown.

Description. Shell broadly ovoid, spire with turreted 
profile, solid, pointed, cream in colour with 4-5 
irregular spiral brown bands sometimes faded partially 
or totally. Protoconch with 2.25 whorls, a diameter of 
about 500 pm, a nucléus of about 100 pm, 1.5 smooth 
whorls and the last 3 A bearing about 20 curved axial 
ribs. Teleoconch of about 3-4 whorls, ail having a 
very prominent subsutural shoulder with the upper 
part of the whorls almost horizontal. Each whorl has 
about 7-8 almost orthocline or slightly opisthocline 
axial ribs, more prominent on the shoulder and much 
naiTower than their interspaces. Spiral sculpture of 
very numerous and variable cordlets (about 14-16 on 
the first whorl), 20-22 on the second, 22-23 on the 
third and more than 60 on the body whorl, sometimes 
with intervening cordlets developing. Under high 
magnification the cordlets can be seen to be rugose, 
bearing numerous rounded rough nodules which
