the Austrian expedition, which we have not yet received in Calcutta 

 from these islands. The almost total want of CoLUBitiDiE on the 

 Nicobars is remarkable. 



From Penang I have to add to the Amphibia a form which appears 

 to be a third interesting variety of the very variable Rana gracilis, 

 and two new species, Polypedates Hascheanus and Ansonia Penangensis 

 (n. gen. et sp.). Among the Ophidia I procured a new Trimereswnis, — 

 T. convtctus, — rather closely allied to the Himalayan T. monticola, 

 G ii n t h., and a very interesting species of Mabouya, — 31. Jerdoniana 

 — which I got on the little Pulo Ticlius, close to the northern shore 

 of Prince of Wales island. 



I have also added a complete description of the rare Gecko Smitkii, 

 Gray, a specimen of which was sent to me from Java, and that of 

 what appears to be a full grown specimen of Tetrayonosoma efrene, 

 Cant., from the island Banca. 



From Amherst, near Moulmein, I have recorded a new species of 

 the rare genus Cantoria, and from Martaban a very interesting small 

 Riopa. At the last locality, I also obtained Jerdon's Biplcpelma 

 Camaticum, Caloula pulclwa, Gray, Hylorana Tyileri, T h e o b., 

 Hinulia maculata, B 1 y t h, and some others. 



The following is a complete list of the species noted in the pre- 

 sent paper ; the families are quoted, according to Dr. G ii n t h e r ' s 

 work on " Indian Eeptiles."
