| Placostylus ambagiosus annectens Powell, 1938 |
Placostylus ambagiosus annectens is a large rare terrestrial gastropod mollusc in the family Bulimulidae, endemic to the Spirits Bay area of Northland in the North Island of New Zealand. It is found at an altitude of about 900 ft between Spirits Bay and Tom Bowling Bay, in mixed forest, and also near the mouth of the Huka Stream.
The shell is very large, the largest form from the New Zealand mainland. The colour of the exterior is dark chocolate with a very narrow subsutural white line, peristome orange and the interior of the aperture brownish-red. The aperture has five processes represented, all but the parietal tubercle well developed. Examples from the Huka Stream mouth are smaller.
Height is up to 94 mm, and width up to 40 mm.
Placostylus ambagiosus annectens is classified by the New Zealand Department of Conservation as being Nationally Endangered.
