CATALOG OF ORIGINAL DESCRIPTIONS: Globigerina calida Parker 1962
This page provides data from the catalog of type descriptions. The catalog is sorted alphabetically. Use the current identification link to go back to the main database.
Original Description Test trochoid, with a low spire and rounded, highly lobulated periphery: chambers fairly rapidly enlarging, early ones spherical, later ones somewhat elongated radially, 5 in the initial whorl, 4-5 in the final one, up to 15 in the adult test; sutures distinct, depressed, radial on both sides; wall calcareous, radial, perforate, hispid, with long fine spines in living forms; aperture umbilical, semicircular, becoming umbilicalextraumbilical and highly arched in the peripheral plane in some adults, with a narrow lip. Size: Largest diameter up to 0.8 mm., thickness up to 0.42 mm.; proloculus diameters 15- 19 µm, average 15-16 µm (9 specimens, type locality} . Extra details from original publication Comparison: Adult specimens have a tendency to become plan ispiral, with the apertures approaching an interiomarginal position. For this reason, the apertures are not always plainly visible from the umbilical side and appear as slits. This is one of the differences between this species and G. bulloides. It differs from that species also in the radial elongation of the final chambers, and in having a somewhat less hispid, thinner wall. The chambers are less involute than are those of young, trochoid Globigerinella siphonifera and the walls are less densely hispid than those of that species.
Distribution: In South Pacific sediments, G. calida is found north of Lat. 35° S. in the vicinity of New Zealand, and north of 30° S. farther to the east.
