A heteroteuthin ...
- with mantle free from head dorsally.
- with elongate distal arm suckers without constricted necks.
- ventral shield without anterior notch.
Characteristics
- Arms
- Distal suckers on arms with elongate suckers and stalks without constricted necks, or distal suckers absent, replaced by leaf-like lobes (sexual dimorphism??).
- Web between dorsal arms extensive. Click on an image to view larger version & data in a new window

- Funnel locking-apparatus with a deep, broad pit anteriorly and an elongate pit posteriorly.
- Mantle
- Dorsal mantle free from head.
- Ventral mantle shield extends anteriorly past base of arms.
- Anterior margin of shield without median indentation for funnel.

Figure. Left - dorsal view of N. pourtalesii. Drawing from Verrill (1883). Middle, Right - Dorsal and ventral views of N. pourtalesii, holotype. Photographs by R. Young.
- Fins
- Fins extend anteriorly beyond the dorsal mantle margin but do not reach the mantle margin posteriorly.
Comments
The holotype (NMNH 729734) presumably is a male judging from the arm sucker modifications. The mantle has not been cut open to verify the sex.
