VIII, D. 5 Wharton: Hirudo boyntoni' 371 



This leech is very common in ditches, small streams, and pools 

 in the rice paddies of the lowlands of Luzon and of other islands. 

 This description is based on specimens from Novaliches, Rizal 

 Province. Specimens have been obtained from practically all of 

 the lowland provinces of Luzon and from Negros, Iloilo, Palawan, 

 and Cebu. I find that it is sold in some of the native drug stores 

 of Manila in place of H. medicinalis. Although a paper on the 

 leeches of the Philippines is in the course of preparation, it seems 

 advisable to publish a diagnosis of this species at once, A more 

 detailed description with drawings will be given at a later date.
