example, tvillmori of Malaya (Leicester) is different from 

 wilhnori of India (James and Liston). One regretable result 

 of this confusion is that the knowledge gained of malaria- 

 carrying species in one country is rendered valueless in its 

 application to the circumstances of the other. 



The present pax^er embodies the results of a study of a large 

 series of Malayan Anopheles and comparison of these with 

 specimens of the Indian species and with the type specimens in 

 the British Museum. The individual species are not described, 

 but a table is appended showing how those may be recognised 

 which are considered to be of undoubted validity.
