Description
Lectotype: BMNH RR 1946.9.5.24 (1910.3.18.84), adult, from the west side of Mt. Seychellois, altitude 1200 ft. Mahé, collected in 1910 by J. Stanley Gardiner.

Paratype: BMNH RR. 1946.9.5.25 (1910.3.18.85 yg), Cascade, Mahé; collected in 1910 by J. Stanley Gardiner.

Short species, generally less than 112mm; tentacle closer to nostril than to eye, separated from the eye by a distance three times as great as that from the nostril; scales present; teeth in four series; tongue with narial plugs; short tail with one or two folds behind the vent, which is narrowly transverse with denticles fore and aft and larger median lateral ones bearing small anal glands; primaries not know to exceed 70; distance between the eyes is less than the length from eye to snout tip; snout projects strongly beyond the mouth; first collar behind the occiput is well defined with short transverse dorsal and ventral grooves, second collar is approximately the same size with a longer transverse dorsal groove; brown with grooves slightly lighter, ventral surfaces are somewhat lighter with a yellow cream spot present at the vent (modified from Taylor 1968).

Distribution and Habitat

Seychelles Islands: endemic to Mahé.

Typically all Grandisonia species are fossorial and can be found under leaves, stones, decaying wood, and in wet soil. Distribution is thought to be limited to the availability of moist habitat rather than elevation.

Life History, Abundance, Activity, and Special Behaviors

All species of Grandisonia are believed to be oviparous. It has been reported that G. brevis is a direct developing species.

Grandisonia brevis is known from two specimens which were collected in 1910. This species is extremely rare if not exctinct.

Trends and Threats
A permit is required for their collection. They are potentially endangered by habitat destruction.

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
