ABSTRACT
Among the biological material collected during the 1998-2001 "INVEMAR-Macrofauna"
cannpaigns aboard the R/V Ancón along the upper zone of the continental slope of the
Colombian Caribbean, at depths ranging from 200 to 520 m, a total of 104 gastropod
species were obtained. Besides 18 not yet identified species, but including one recently
described new species [Arm'ina juliana Ardila and Díaz, 2002), 48 species were not pre-
viously known from Colombia, 18 of which were also unknown from the Caribbean Sea.
Of the 36 families represented, Turridae was by far the richest in species (26 species). An
annotated list of the taxa recorded is provided, as well as illustrations of those recorded
for the firsttime in the área.
RESUMEN
Entre el material biológico colectado en 1998-2001 durante las campañas "INVEMAR-
Macrofauna" a bordo del B/l Ancón, a profundidades entre 200 y 520 m, se obtuvo un
total de 104 especies de gasterópodos. Aparte de 18 especies cuya identificación no ha
sido completada, pero incluyendo una especie recientemente descrita (Armina juliana
Ardila y Díaz, 2002), 48 especies no habían sido registradas antes en aguas colombia-
nas y 18 de ellas tampoco en el mar Caribe. De los 36 familias representadas, Turridae
fue la más numerosa en especies (26 especies). Se ofrece una relación anotada de las
especies colectadas, así como ilustraciones de aquellas que se registran por primera vez
para el área.
