OLIVELLA. 09 



0. LEPTA, Diielos. PL 10, figs. 4-11 ; PL U, 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 i figs. 5, , 0. lanceolata, Rve. (figs. 7, 8), 0. 



2Jiilicaria, Marrat (fig. 9), 0. exilis, Marr. (fig. 10), 0. fulgurafa, 



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



0. FoRTUNEi, Adams. PL 10, 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. sj^reta^ 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. PL 10, figs. 10, 1*1. 



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. 



Se7iegal. 

 O. Anazora, Duclos. PL 10, 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, Avill be able to reduce the number 



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



certain types of variation in form and coloring. 



Length, 8-13 mill. 



Xipixapi, W. Columbia; Acapulco; Mazatlan.
