Material examined

MAURITIUS • 1 ♂ (66.3×39.9); 1850; MNCN20.04/00118 • 1 unsexed (66.3 ×39.9); 1850; MNCN20.04/00117 • 2 ♂♂ (66.9× 39.9, 98 × 54.2), 4 ♀♀ (42.6 ×27.2, 31.3 ×20.7, 40.4 ×26.6, 46.7 ×29.9); 1850; Guérin-Méneville leg.; MNCN20.04/00618 .

Remarks

All the specimens had the previous identification as Calappa tuberculata (Fabricius, 1787) . The specimens MNCN20.04/00117 and MNCN20.04/00118 are dry preserved inside a glass and wood box. Both specimens were previously held by a large needle positioned through the centre of the carapace. The specimen MNCN20.04/00118 has the shell cracked in half. There are still remnants of the old codes that were annotated on the specimen itself. Those codes correspond to the ones used for the catalogue published by San Miguel de la Cámara in 1910 (ACN0287/001). The specimens MNCN20.04/00618 are covered with fungi, a sign that at some point they lost the ethanol and were dried out.

For identification see also Galil (1997).
