IV.— Contributions to the Herpetoiogy of 

 Borneo. By Malcolm A. Smith, f.z.s. 



I am indebted to Dr. Eric Mjoberg for the pleasure of exa- 

 mining the extensive collections of reptiles and amphibians 

 made by him in the State of Sarawak during the past two years. 

 These have been forwarded from time to time as they were 

 obtained and the present article concerns the combined 

 material, with the exception of one collection from Mt. Mnriid 

 which has been dealt with in a previous paper (vide pp. 

 5--14). 



Some of the districts visited by Dr. Mjoberg, notably Mt. 

 Dulit and Mt. Penrissen, are already well known as collecting 

 grounds, but others such as Mt. Matang, Mt. Poi and Mt. 

 Gadin, but little known to herpetologists outside Sarawak, have 

 been productive of much that is interesting. 



Altogether some 700 specimens have been obtained, distri- 

 buted over 95 species. The most noteworthy are a diminutive 

 form of toad allied to MegalopJirys which appears to represent 

 a new genus, and an undescribed ground-Gecko of the genus 

 Gonatodes. The collection also, in addition to containing 

 several species which have not been previously recorded from 

 Borneo, permits the status of many other little known species 

 to be discussed. Where no departure from the text-book des- 

 cription has been met with no comment has been made, and 

 the locality only in which the species was obtained is 

 mentioned. 



In working out this material and comparing it with another 

 collection recently obtained by my Siamese collector in the 

 northern part of the Malay Peninsula (Patani and Kuan Nieng 

 near Patalung), I have been struck by the close association of 

 the faunas of these two regions. Of the 47 species obtained by 

 him which are common to the Malay Peninsula and the Archi- 

 pelago, no less than eight are to be found, in the Archipelago, 

 in Borneo alone.
