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

 thostoma, and Descriptions of Four new Species. By 

 Edgae A. Smith. 



A populak 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 O. otostoma, 

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

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