Plates: Ocular plates relatively large, the two posterior plates in contact; only four genital plates (Cooke, 1953)
Madreporite: Central (Cooke, 1953)
PERIPROCT (ANUS): Shape & Size: Large; pyriform (Cooke, 1953)

SPECIMENS STUDIED & CONDITION: Holotype USNM 108375 . Species represented by 39 individuals (Cooke, 1953).
ETYMOLOGY: Named in honor of Thomas Wayland Vaughan (1870–1952), a prominent American geologist, oceanographer, and paleontologist who worked with the U.S. Geological Survey and the U.S. National Museum (Smithsonian).
REMARKS & COMPARISONS
Remarks: This species has little variation in shape (Cooke, 1953).

REMARKS & COMPARISONS
Remarks: This species has little variation in shape (Cooke, 1953).
Comparisons:
- Globator nucleus: G. vaughani is less globose.
- Globator cylindrica & G. ataciana: G. vaughani is narrower behind.
- Globator desmoulinsii: G. vaughani is more inflated and less symmetrical.
All these species share the terminal periproct location (Cooke, 1953).
