3* If H. gerrardi be really distinct from this species, which I greatly doubt. Tosh's figure 

 (Marine Biologist's Report 1903, p. 4, pi. 5, fig. 2) suggests its occurrence on our south coast (Nerang 

 Creek). 



35 Garman 's assumption of the identity of o\ir species with P. Untaculata is distinctly unhappy; 

 the constantly shorter annulated tail and uniformly umber brown coloration distingviish it at a 

 glance from that species.
