XXXVI. — A List of the Bornean Species of the Genus Opis- 

 thostoma, and Descriptions of Four new Species. By 

 Edgae a. Smith. 



A POPULAR account of the species of Opisthostoma from Borneo 

 was published by the writer in March of this year in the first 

 number of the new series of ' Science Gossip.' In addition 

 to the ten different species there referred to, I have now to 

 mention one described by Dr. Boettger and four new forms, 

 of which diagnoses are now given. 



All the known species, with the exception of 0. otostoma^ 

 Boettger, have been figured; and as the present paper is 

 unillustrated, it is proposed to give figures of the new forms
