OLIVA. 85 



0. DUCLOSI, Reeve. PI. 32, figs. 12-17. 



Shell with close reticulations and triangular markings of 

 chestnut, with narrow, interrupted sutural and median bands, 

 aperture yellowish brown. Length, -9-1-25 inches. 



China, Philippines, Australia, New Zealand, Polynesia. 



0. flammulata,'Ijiim., is too closely allied to varieties of this 

 species ; I have hesitated to separate them. 0. lentiginosa, 

 Reeve (fig. 14), is merely a lighter-colored specimen ; 0. esodina, 

 Duel. (fig. 15) and 0. Natalia, Duel. (fig. 16), are also synonyms, 

 and I suppose that 0. Sandwichensis, Pease (fig. 17), may also 

 be added. This is the 0. jaspidea, Duclos (not Olivella jaspidea, 

 of Gmelin), under which name it is as generally known as that 

 of Reeve. 



0. THOMASI, Crosse. PI. 32, fig. 18. 



Heavy, oblong, with rather short spire ; flesh-color, obscurely 

 two-zoned, numerously punctate, maculated with chestnut at the 

 suture ; yellowish white, obscurely bifasciate within the aperture. 



Length, 28 mill. 



Tahiti. 



Is possibly a variety of 0. Jiammulata, judging from the 

 figures and description. 



0. AUSTRALIS, Duclos. PI. 32, figs. 19-20. 



Spire elevated; white or yellowish, with light chestnut or 

 purple-ash zigzag lines ; interior of aperture white, maculated 

 with purple near the margin. Length, '75-1 inch. 



Australia, New Guinea. 



Mr. John Brazier informs me that the natives of New Guinea 

 place these shells on red-hot ashes, which discharges the coloring, 

 leaving them entirely white ; in which condition they are strung 

 to make neck-ornaments and girdles. 0. caldania, Duclos (fig. 

 20) is a synonym. 



O. PAXILLUS, Reeve. PL 32, figs. 21-23. 



Shell thick, stout, cone-shaped, with a high spire ; white, with 

 triangular brown markings, forming interrupted bands, and spots 

 beneath the sutures and on the fasciole ; interior of aperture 

 sometimes two or three banded. Length, '85-1-1 inches. 



Japan, Philippines, Australia. 



The form of this species is its best characteristic. 0. ozodona,
