plentiful. At the mouth of the Endeavour Eiver the coast was 

 strewn with dead and broken tests of the species. Using a very 

 small dredge at about ten fathoms one can obtain hundreds or 

 thousands of specimens anywhere between Cape Grenville and 

 Port Denison. 



Maretla plamdata, Leske, is also a very com^mon species and is 

 found on a sandy bottom at moderate depths from about five 

 fathoms. We know very little about the Spatangidce, but their 

 habits might be easily studied in Sydney with even a small 

 aquarium. The peculiar smooth actinal plastron points no doubt 

 to some distinct habits and modes of getting its food, which would 

 be very interesting to study. Though it is not at all rare on the 

 east coast, yet because the test is very brittle it is never found on 

 the beach. Any s])ecimens that are washed up must be broken 

 to pieces. This shows how notliing but the dredge will reveal 

 what urchins we have in Australia. 



Eclivnocardium &mfrale, Gray. This species is abundant on 

 sandy shores, from Port Jackson to East Tasmania. Like all the 

 clypeastroid urchins it seems to feed on Foraminifera. 



Breijnia aicstralasice, Gray, is extremely abundant in the sandy 

 shallow bays about Port Denison. 



Rhjnolrmus aiyicalis, nohis. Small specimens of this urchin 

 have lately been found in Port Jackson at sixteen fathoms. They 

 were not one-fourth the size of the type specimen obtained by 

 me from Moreton Bay.
