The species differs from Otojjhidium tige^'imos in its shorter and 

 deeper body, longer head, much larger eye, anterior insertion and 

 much greater length of the ventral filaments, absence of an 

 enlarged outer row of teeth, &c., and should not perhaps be 

 included in the salne genus. 



The only specimen as yet seen was collected by Mr. Whitelegge 

 on Maroubra Beach during the current month and measures 42 

 millimeters. 



Its register number in the Australian Museum is I. 3660.
