Introduction

Material of Histioteuthis meleagroteuthis examined by Voss et al. (1998) and earlier workers cited therein found no indication of population differentiation over the broad geographical, but interrupted, range of this species. However some variation in the sucker enlargement pattern of the club is a possible exception. Additional squid are needed to evaluate the latter. Also, descriptions of spermatophores from different geographical regions are needed.

Brief diagnosis:

A Histioteuthis ...
