subgenus Eiiclia based on the moipholog\' of its colvmiellar
plications, spiral sculpture, and o\erall shell shape. It is readiK
distinguished troni the other Recent members ot the subgenus
b\ its lack ol a distinct shoulder vvnth spines or nodes and finer
spiral sculpture.
Key words: Cancellariidae. Panamic Pro\ince, eastern Pacific,

INTRODUCTION
This paper describes a new species of cancellariiil that
was recenth' trawled from bath\al depths in the Golfo
de Chiriqui. Panama. Based on conchological features,
it is assigned to the genus CanceUaria Lamarck, 1799.
subgenus Eiiclia H. & A. Adams. 1854, which, in its
Recent geographical range, is endemic to the tropical
eastern Pacific. While similar to the Recent species Can-
ceUaria {Eiiclia) cassidifonnis Sowerby, 1832, and C. (£. )
halboae Pilsbrv, 1931, this new species is more similar
to the Miocene C. (E.) dinota Woodring, 1970, from the
Gatiin Formation of Panama and especially the Late
Miocene/Earlv Pliocene C. (E.) maldonacloi Olsson,
1964 of the Angostura Formation of Ecuador than to
either of the Recent species. The taxonomic historv of
the subgenus Eiiclia is briefl\' reviewed, and a table of
included species provided.
