摘要：

Morphologic characteristic and classification description of female octopus Pareledone turqueti collected by R/V Xuelong during the 22nd Expedition in the Antarctic waters is discussed. The results indicate that this species belongs to suborder Incirrina, Family Octopodidae, Subfamily Eledoninae, Genus Pareledone,Pareledone turqueti. It is characterized by having soft and smooth skin without papillae,funnel organ VV-shaped, crop, ink sac, anterior and posterior salivary gland present, developed radulae with 7 small heterodont teeth, gills with 7 lamellae on the inner and outer demibranch respectively. Arms moderate with uniserial suckers no enlarged, arm formula is Ⅱ=III I=IV, web formula is c=d.e.b.a.
