ABSTRACT. Antillophos bahamasensis Petuch, 2002, previously known only from the type 
locality, is recorded from Guadeloupe. The species is redescribed based on this additional material. 
Watters (2009) reviewed the western Atlantic 
Océan species of Antillophos. At the time the species 
Antillophos bahamasensis Petuch, 2002, was known 
only from the faded holotype and a single paratype 
collected off Victory Cay, Bimini Chain, Bahamas, 
apparently from 35 m (Figures 1, 2). Because of the 
lack of material a description of the variability of the 
species was not possible. It was suggested that the 
species might even prove to be synonymous with the 
widespread Antillophos chazaliei (Dautzenberg, 
1900). 
After publication of the review I was fortunate to 
receive numerous lots of Antillophos from 
Guadeloupe sent by Mr. Dominique Lamy. Five 
species were represented, some in abundance: A. 
chazaliei (Dautzenberg, 1900), A. candeanus 
(d’Orbigny, 1842), A. smithi (Watson, 1885), A. 
beauii (Fischer and Bemardi, 1857), and surprisingly, 
A. bahamasensis. Specimens of A. bahamasensis were 
recorded from Saint-Françoise, Grande-Terre (250 m) 
(Figure 3, 4), Basse-Terre (350 m) (Figure 5), and 
Port-Louis, Grande-Terre (150 m). At least one 
specimen was live-taken and the species was found 
either alone or in association with A. smithi and A. 
beauii. Antillophos bahamasensis appears to live in 
deeper water than most western Atlantic Antillophos 
and is obviously very rare in collections. These are 
also the fi rst published records of A. candeanus and A. 
chazaliei from Guadeloupe, although well within the 
overall range of both species. 
These new specimens not only increase the range 
of the species significantly, but indicate that the 
species is distinct from A. chazaliei, as well as 
allowing a more comprehensive description of the 
species beyond the type lot. Although quite similar, A. 
bahamasensis differs from A. chazaliei (Figure 6) in 
having more numerous axial ribs on the penultimate 
whorl (11 — 17 in A. bahamasensis, 8 - 12 in A. 
chazaliei), in having less pronounced sculpture, and in 
having the lirae in the outer lip broken into pustules 
(entire in A. chazaliei). The description given by 
Watters (2009) is herein modified and additional 
specimens are figured. 
Description. Shell 12.8 - 18.0 mm in length. 
Fusiform; spire 50% - 60% of total length. 
Protoconch conical, of 2.25 - 2.5 smooth whorls with 
sharp keel at periphery near suture. Teleoconch of 6.5 
whorls. Teleoconch whorls sculptured with narrow, 
widely spaced, fiat, spiral cords separated by wide 
intervals, 14 - 17 on last whorl. Some interspaces with 
a single, fine, 2° spiral thread. Axial sculpture of 
widely-spaced, low, rounded ribs, 11 - 19 on last 
whorl (excluding varices) and 11 - 17 on penultimate 
whorl (excluding varices). Varices well-developed, 
about one varix every 1/3 - 1/4 tum including final 
last whorl (not apparent on holotype); occasionally 
varices may be adjacent to each other. Terminal varix 
low, wide, crossed by numerous axial ribs. 
Intersections of axial and spiral sculpture form 
pustulose, rachet-like sculpture. Aperture elongate- 
oval, with one plication anteriorly; anal canal set off 
by one or two denticles. Outer lip with 12-17 lirae 
deep within mouth, with oceasional intercalated 2° 
ones; the primary lirae are broken up into peculiar 
linear pustules. Columella continuous; pariétal lip 
adhèrent to previous whorl. Siphonal canal short, 
open. “Stromboid notch” shallow to of medium depth. 
Base color grayish-white, most specimens hâve some 
evidence of three brown spiral bands at suture, 
periphery, and siphonal canal; terminal varix always 
white without spots. Aperture white. Operculum leaf- 
shaped, tan, with anterior terminal nucléus. Radula 
and anatomy unknown.
