AMB: Amb shape: Narrow, lanceolate (Clark & Twitchell, 1915)
Amb width: Less elevated than the interambulacra (Clark & Twitchell, 1915)
Amb primary zones: Poriferous zones straight and depressed (Clark & Twitchell, 1915)
INTERAMB: Interamb width: Broad (Clark & Twitchell, 1915)
PORE PAIRS: Shape: Small, oval (Clark & Twitchell, 1915)
Arrangement: Uniserial (Clark & Twitchell, 1915)
TUBERCLES: Primary tubercles: Numerous small tubercles; larger and more distinct on lower surface than upper (Clark & Twitchell, 1915)
Granules: Fine microscopic granules disseminated between the tubercles (Clark & Twitchell, 1915)
APICAL SYSTEM: Size / Location: Small (Clark & Twitchell, 1915)
Plates: 4 genital plates; 5 small ocular plates firmly wedged between ovarial plates (Clark & Twitchell, 1915)
Genital pores: 4 genital pores (Clark & Twitchell, 1915)
Madreporite: Large; right antero-lateral modified to form madreporite (Clark & Twitchell, 1915)
PERIPROCT (ANUS): Shape & Size: Oval (Clark & Twitchell, 1915)
Location: Supramarginal; placed nearly in the center of the posterior margin (Clark & Twitchell, 1915)
PERISTOME (MOUTH): Size: Large (Clark & Twitchell, 1915)
Shape: Elliptical (Clark & Twitchell, 1915)
Location: Obliquely situated slightly in front of the center of the base (Clark & Twitchell, 1915)
SPECIMENS STUDIED & CONDITION: Hypotype NPL 83004 .
ETYMOLOGY: Named in honor of Dr. C. C. Parry (1823–1890), a botanist and geologist with the United States and Mexican Boundary Survey who collected the type specimens (Hall, 1857).
REMARKS & COMPARISONS
Remarks: This species shows considerable variation but is regarded as a single species. It was historically the only representative of the genus from American strata (Clark & Twitchell, 1915).

REMARKS & COMPARISONS
Remarks: This species shows considerable variation but is regarded as a single species. It was historically the only representative of the genus from American strata (Clark & Twitchell, 1915).
Comparisons:
- Pyrina desmoulinsii D'Archiac: G. parryi is broader posteriorly and less elevated (Clark & Twitchell, 1915).
- Globator clarki (Böse): G. parryi differs in outline and convexity (Böse, 1910).
