have found to be quite impossible. Any Member who desires to 

 help, and 1 hope there may be many, need only study the heading 

 ' Other localities ' and compare it with the Appendix to be able to 

 see for himself the direction in which he can best help. T may 

 take this opportunity however to point out that what is most 

 required are series from the fauna which surrounds the Collector, 

 and that recorded details of locality and date accompanying a speci- 

 men enormously increase its value, and finally that a series is very 

 much more valuable than single specimens. 



In conclusion I venture to offer my congratulations to Messrs. 

 Millard and Kinnear on the great success of the Survey to date, 

 which is so lareelv due to their untirinjif services in its organisation 

 and administration, and to the work in the field of Messrs. Crump, 

 Shortridge, Mayor, Prater, and N. A. Baptista. I triTst that the 

 example set by Mr. J. M. D. Mackenzie, I.F.S., in making col- 

 lections in the Chin Hills and Pegu in aid of the Survey may find 

 many imitators. Finally I desire to record my indebtedness to my 

 friend Oldfield Thomas, who originallj^ suggested this Summary, and 

 without whose continuous advice and help I could not have comple- 

 ted it ; also to Mr. W. R. Sherrin of the Natural Plistory Museum, 

 whose ever ready help in handling the specimens and recording the 

 results has enormously lessened my labours.
