OLIVELLA. 09 



O. LEPTA, Duclos. PI. 16, figs. 4-11 ; PL IT, fig. 52. 



Narrow, with elongated spire ; a narrow chestnut line or row 

 of spots beneath the suture, a more distinct interrupted line at 

 the margin of the fasciole, and the intermediate space with 

 zigzag longitudinal lines, base of shell chestnut. 



Length, 8 mill. 



China Sea; Japan; Philippines. 



With this species I include 0. consobrina, Lischke (unfigured), 

 0. fabula, Marrat (figs. 5, 6 , 0. lanceolata, Rve. (figs. T, 8), 0. 

 pulicaria, Marrat (fig. 9), 0. exilis, Marr. (fig. 10), O.fulgurata, 

 Ad. and Reeve (fig. 11), and 0. pellucida, Rve. (fig. 52). 



0. FORTUNEI, Adams. PI. 16, figs. 12-15. 



Widely fusiform, maculated or covered with zigzag longitu- 

 dinal chestnut markings, fasciculated at the sutures. 



Length, 8 mill. 



China; Japan. 



Yery similar to the last species in markings, but differing in 

 form. I can see no good reason to separate 0. pulchra, Marr. 

 (fig. 14), a species described without locality, and I agree with 

 Weinkauff that the unfigured 0. signata, Lischke, is also very 

 closely allied. Perhaps 0. spreta, Gould, may belong here ; the 

 author never figured it and the type, I suppose, was destroyed 

 by fire, in Chicago ; I give a figure which E. A. Smith identifies 

 with this species (fig. 15). 



0. LEUCOZONIAS, Gray. PI. 16, figs. 16, IT. 



Orange-yellow, with zigzag chestnut lines and maculations, a 

 white band at the suture, spotted with chestnut, and another 

 white band below the middle of the shell. Length, 12-15 mill. 



Senegal. 

 0. ANAZORA, Duclos. PI. 16, figs 19-23. 



Markings similar to those of the two preceding species, with 

 a form about intermediate between them. I am not able to give 

 any better distinction than the very different locality; indeed, 

 the probability is that the future conchologist, with specimens 

 from more numerous stations, will be able to reduce the number 

 of species of Olivella to a very few, each of them presenting 

 certain types of variation in form and coloring. 



Length, 8-13 mill. 



Xipixapi, W. Columbia; Acapulco; Mazatlan.
