ENTEROPNEUSTA FROM MADRAS. 131 



tlie perianal band of cilia^ on the side turned towards the 

 month. A smaller ring of such patches^ often appearing as 

 slight elevations, is present round the anus. These, no 

 d(nibt, represent a vestigial secondary perianal ring. These 

 patches agree in colour with the transversely elongated 

 patches found on the body of Grlandiceps haekii, and 

 possibly the larva belongs to this species. 



It may be added here that, in his monograph, Spengel 

 mentions two forms, Ptychodera (Chlamydothorax) 

 Ceylonica, and Tornaria grenacheri, which were ob- 

 tained in Ceylon.
