ORGANISMS DIVERSITY AND EVOLUTION 6(2):151-162] is a rare species of turtle found in the Western Ghats of India.Type locality: "Near Kavalai in the Cochin State Forests, inhabiting dense forest, at an elevation of about 1500 feet above sea level," India.

Description

Carapace considerably depressed, with prominent vertebral and thin lateral keels; posterior margin feebly reverted, not serrated. Nuchal shield small ; first vertebral shield broader in front than behind, larger than the second, third, and fourth, which are considerably broader than long and as broad as the costals. Plastron large, nearly as large as the shell opening, angulate laterally, openly emarginate anteriorly and posteriorly ; the width of the bridge is less than the length of the hind lobe ; the longest median suture is between the abdominal shields, the shortest between the gular ; axillary and inguinal shields very small, one of the latter being absent.

Head rather large : snout as long as the orbit, truncate ; upper jaw hooked ; mandibular symphysis very long, longer than the greatest diameter of the orbit. Skin of the hinder part of the head divided into moderately large shields.

Arms with enlarged, squarish or pointed, horny scales, chiefly on the front; hind-limbs more or less club-shaped, the anterior margins and region of heels with enlarged horny scales. Fingers one-third webbed, toes with a rudiment only. Tail short.

Shell dark bronze above ; yellowish below, with two dark blotches on either side, upou the bridge. Front part of head above, and jaws, bright yellow in life, with a red spot on the top of the snout; hinder part of head and neck brown. Limbs and tail black.

Length of shell 120, breadth 83, depth 45 mm.

The above is a description of the type specimen, a male. A second and less mature specimen is in the Madras Museum. Both were obtained in the dense forests of Cochin at an altitude of about 500 metres. According to the natives from whom Dr. Henderson obtained the type, the species inhabits short burrows underground and does not affect the neighbourhood of water. Both specimens were kept in captivity for six months, and Dr. Henderson remarks that they did not show any special partiality for water and when handled did not emit the offensive odour which" G. trijuga" does. They lived entirely upon vegetable food. [Smith, M. A. 1941. Fauna of British India. Reptilia and Amphibia]
