Introduction

This is the type species of the genus. The type locality is off Messina, Italy. The type is thought to be at the Museum National d'Histoire Naturelle, Nice (Sweeney and Roper, 1998). We have recently examined two small squids from the Mediterranean Sea that do have the visceral photophore in contrast to the description given by Naef below. As a result, the identity of C. sicula remains uncertain as two species appear to be present in the Mediterranean Sea.
