A LIST OF THE CROCODILES. TORTOISES, TURTLES AND LIZARDS 



at present known to inhabit siam. 

 By Malcolm Smith, m.r.c.s., l.r.c.p. 



The following list comprising 4 orooodiles, 21 tortoises and 

 turtles, and 66 lizards, cannot by an_v means be considered to represent 

 the total number of species which will ultimately be found to inhabit 

 this country. Of the fresh-water tortoises and turtles of Siani proper, 

 practically nothing is yet known, whilst in the large family of lizards, 

 particularly among the geckoes and the smaller species of skinks, many 

 forms must still remain to be discovered. 



Numerous additions have been made since Stanley Flower com- 

 piled his list in 1899, the last naturalist to make a complete list of the 

 reptiles of Siam. Most of these additions are from the Peninsula, and 

 have been incorporated in Mr. Boulenger's recent work on the Reptiles 

 of the Malay Peninsula. 



Acanthosaura horrescens and Jsojiachi/s rii/ldenstolpei were dis- 

 covered by Count Gyldenstolpe in 1911, and described tliis year 

 (Results of the Swedish Zoological Expedition to Siam, 11, Lizards). 



I have added 1 tortoise and 17 lizards to the list myself, amongst 

 which may be mentioned GymnodaHi/lus oldhami, Li/ijosoma oliraceum, 

 L. vittiijerum, L. laferale, and Tropidophorus yunnanensis and cochin- 

 chineims, together with the four new species which have already been 

 described in the pages of this Journal. Tlie remainder, although not 

 definitely recorded from tlie country before, might, from their previous- 

 ly known distribution, have been reasonably expected to occur here. 



Certain clianges in nomenclature have been made, which are as 

 follows. 



Cyclemi/s onnandaln becomes the t3'pe of a new genus. The 

 skull of this tortoise, in its absence of a bony temporal arch, resembles 

 Qeoeiiiyda, but in other characters it differs sufficiently to merit separa- 

 tion from it, and to be placed bj' itself. For this new genus Mr. 

 Boulenger has proposed the name Hieremys, as the original specimens
