Peruvispira gundyensis Yoo

PI. 8 figs 4-8

Peruvispira gundyensis Yoo, 1988: 242 , figs 29-32.

Additional material. 57 specimens from 'Marohn' (Locality 28), 23 from south-east of 'Rangari' (Locality 18), 15 from Swains Gully (Locality 25), 61 from various horizons at Glenbawn (Localities 29-32).

Geographic distribution. 'Rangari' to Glenbawn.

Geological age. Early to late Tournaisian.

Remarks. The difference of this species from Peruvispira kempseyensis Campbell, 1962 and Peruvispira kuttungensis Campbell, 1961 has already been discussed ( Yoo, 1988). This species is very common between 'Rangari' and Glenbawn with some minor variations. The ontogenetic development of this species is well displayed in Plate 8 figure 6.
