446 MOLLUSCA FROM THE HOPE ISLANDS, N. QUEENSLAND, 



Mr. Gabriel has lent me specimens of 0. eutropia, identified 

 by its author. These agree with a common and variable shell 

 iirst described from the Clievert Collection. It was abundant at 

 the Hope Islands. I have also traced it south to the Palm 

 Islands and Port Curtis, and westerly to Yan Diemen's Inlet in 

 the Gulf of Carpentaria. Mr. Melvill notes it from Bombay and 

 the Persian Gulf. Another Australian species which the same 

 author has carried as far west, is Capulus violaceus Angas."^ 



Odostomia gumia, n.sp. 

 (Plate xli., tig.67.) 



Shell small, solid, ovate-conical. Colour buff. Whorls five, 

 and a heterostrophe protoconch. Sculpture : prominent spiral 

 ribs, equal in breadth to their interstices, on the body-wdiorl 

 eight, on the earlier three, summits of spirals polished, interstices 

 finely radially striated. Aperture ovate, plication prominent, 

 horizontal, columellar margin reflected over a narrow^ perforation. 

 Length 3-55; breadth 1-6 mm. 



One specimen, from 5-10 fathoms, Hope Island.

Mr. Gabriel has lent me a specimen from the Persian Gulf, 

 identified by Mr. Melvill as 0. ima, which exactly corresponds to 

 large examples of 0. humeralis, from 5-10 fatlioms, off the Hope 

 Islands. Both here and at Mast Head it occurred plentifully. 



A near relation, perhaps indeed another synonym, seems to be
