294 PERCY SLADEN TRUST EXPEDITION. 
of the back; a light line on the coccygeal region meeting a perpendicular one on the 
back of the thighs, which is continued along the inner side of the leg and the tarsus ; 
lower parts brown, with whitish spots and marblings; a L-shaped whitish line along 
the middle of the throat and belly, intersected by another across the breast. 
From snout to vent 45 millim. 
A single female specimen from the Cascade, Mahé, at an altitude of 1500 feet, was 
given to Mr. Gardiner by Mr. H. P. Thomasset, from whom the British Museum had 
previously received the first examples of the allied but dwarfed frog, Sooglossus 
sechellensis. 
7. Sooglossus sechellensis, Bitgr. (Plate 40. fig. 3.) 
Mahé: Cascade, 1800-2000 f. Jorne, 2000 f. 
The largest of the numerous specimens collected measures 25 millim. from snout 
to vent. 
The genus Sooglossus was proposed by me for a single species, Arthroleptis sechel- 
lensis, discovered by Dr. Brauer and accurately described by Prof. Boettger, The figure 
given by Dr. Brauer was intended to show the curious manner in which the male carries 
the tadpoles, other details being neglected. It is therefore desirable to give a correct 
figure of this little-known Batrachian. 
8. Megalixalus sechellensis, Gthr. 
Mahé: Chateau Margot, 1400 f.; Cascade Estate. Praslin. 
The genus Megalivalus is distributed over Tropical Africa and Madagascar. This 
species is confined to the Seychelles. 
A series of larval stages were obtained at Chateau Margot. The tadpole, of a blackish 
brown, is remarkable for its long tail (body 18 millim., tail 44); otherwise it is very 
similar to that of Hylambates. Labial teeth in series.

1. Testudo gigantea, Schweigg. 
A young specimen, nine months old, with divided caudal plate, from Mahé, where a 
number of specimens, originally imported from Aldabra, are kept in a state of semi- 
domestication. 
Mr. Rothschild’s studies on extensive material procured since the publication of the 
Catalogue of Chelonians in the British Museum (1889) tend to confirm my suggestion 
(p. 168) that the species distinguished by Dr. Ginther as 7. elephantina, ponderosa, 
hololissa, and gigantea are founded on individual variations and should be united 
under the oldest name, 7. gigantea *.,
