Obs. — Tliis species is very frequently much distorted, and 

 small forms are often relatively very tumid and solid. Messrs. 

 Tate and May in their Tasmanian census unite Area pusilla, 

 Sowerby, with this species, but we consider it to Vje distinct. 

 The type specimen of Area niaccoyi, T. Woods, is in the National 

 Museum, Melbourne. The type of Area squamosa is from King 

 Island, and is in the Museum d'Historie Naturelle, Paris.

 living commonly to the early colonists in the neighbourhood 

 of Port Melbom-ne. It is very abundant in the old estuarine 

 deposits of the West Melbourne Swamp of Pleistocene age ex- 

 tending as far north as Kensington at least, and it is also com- 

 monly obtained in the dredgings for the harbour improvements. 

 The type of Area lobata. Reeve, is in the National Museum, 

 Melbourne, having been obtained from Reeve many years ago.
