Original Description

Test plano-convex, trochospiral in initial whorls, later streptospiral, left-coiling, consisting of 4-5 whorls, periphery sharply angled, lobulate with the outer edge of the chambers of the final whorl sometimes extending above those of previous chambers near the peripheral edge; chambers rounded and inflated in the earlier part of the test, later ones slightly inflated on involute side, angular and uninflated on evolute side, 4½ to 5½in the final whorl, 4 in the initial whorl, up to about 19 in all; early sutures distinct on both sides, curving, later ones distinct on involute side but obscure on evolute side and only slightly curving; wall of adult smooth and somewhat polished, in young forms coarsely pitted with occasional short spines near the periphery; early apertures almost semicircular becoming increasingly narrow and elongate, very narrow in adult.

Diameter up to 0.83 mm.; height up to 0.50 mm.

Extra details from original publication
This species is quite distinct from its ancestor P. semiinvoluta Germeraad (text figs. 5, 6), differing from that species in its plano-convex test and narrowly angled periphery. P. spectabilis seems to have accelerated rapidly, because the plano-convexity appears early in the development of the test (text figs. 3, 4). Both these species and P. obliquiloculata (Parker and Jones) occur concurrently during parts of their ranges.
