THE VICTORIAN NATURALIST. 



Along the shore margin, and for the most part inside the 

 mangroves, numerous small pans occur where brackish water 

 shells may be collected, amongst which may be mentioned — 

 ibalmator JragiHs, Lamarck {Ampullar ina frai^ilis) ; SaliiuUor 

 quoyana, Potiez and Michaud ; Assiminea brazieri, T. Woods ; 

 Assiminea tasmanica, T. Woods ; and Ophicardelus, n. sp. 



On the sea side of the mangroves, such genera as Nassa, 

 Natica, Thalotia, Columbella, Anapella, Alodiola, and Anatina 

 may be found in almost any number. The species from this 

 locality may be listed as follows : — 



Anatina tasmanica, Reeve 

 Anapella cuneata, Lamarck 

 Chione scalarina, Lamarck 



strigosa, Lamarck 

 IModiola inconstans, Dunker 

 Barnea aiistralasice, Sowerby

costata, Quoy and Gaimard

£n route to the Derby River the swamps and soaks showed an 

 abundance of Bulinvs tenuistriatus and Bulinus p7'oductus, and 

 the coastal dunes showed quantities of dead shells of Succinea 

 australis. Off tlie mouth of the Derby River the reefs of dune 

 limestone, only exposed at low tide, showed Purpura succi7icta, 

 Martyn, Turbo itndulatus, Martyn, Patella tramoserica, Martyn, 

 and Mytilus rostratus, Dunker, very commonly ; also, Haliotis 

 ncevosa, Martyn, Lotorium spengleri, Chemnitz, Patella limbata, 

 Philippi, and Austrocochlea striolata, Quoy and Gaimard, of less 

 frequent occurrence. 



The next locality to receive attention was Tongue Point, but 

 the general ruggedness of the coast hereabouts did not render the 

 ground a favourable one. A few of the ordmary rock-loving 

 species were obtainable, such as — 



Patella limbata, Philippi 



tramoserica, Martyn 

 Littorina mauritiana, Lamarck 

 Acmcea septiformis, Quoy and Gai- 

 mard 

 Mytilus rostratus, Dunker 

 Lasrea rubra, Montagu 



Modiola ater, Zelebor 



Nerita meianotragus, E. A. Smith 



Austrocochlea striolata, Quoy and 



Gaimard 

 Sistrum adelaidense, Crosse and 



Fischer 

 Purpura succincta, Martyn
