The case of the Dipterous larva is figured to show its resemblance to certain sjaecies 

 of Phylactolaematous Polyzoa. When seen living it was mistaken for a colony of this 

 group until a microscopic examination had been made. The larva is described by Mr. 

 Baini Prashad in a separate paper included in this volume.
