compared to Fr'evnlina pulchella Gray. It cannot be confounded 

 with the heavily ribbed Antilh*an A. rubrotiucta. 



A NEW CALIFORNIA EUPLEURA. 



BY \VM. H. DALL. 



The following species was dredged off San Diego, outside the kelp 

 beds, in 15 fathoms, by Mr. C. W. Gripp, whose success in getting 

 new and interesting forms is well known to readers of the Nautilus : 



EUPLKURA GKIPPI, n. Sp. 



Nucleus small, of a single whorl or slightly more, dark chestnut- 

 brown in color, smooth and slightly tilted, followed by four and a 

 half subsequent whorls, with the inception of which the sculpture 

 changes abruptly; the first has two, the second three, the third four 

 spiral threads between the periphery and the subsequent suture; the 

 two original threads stronger than the others, but all becoming rela- 

 tively feebler, and on the last whorl obsolete; the [)osterior slope of 

 the whorls is smooth except for lines of growth; on the last whorl 

 there are very obscure indications of obsolete spiral sculpture; the 

 whorls have, in the type specimen, about five obscure nodes at the 

 shoulder, reminiscent of the varices of the other species of the genus; 

 whorls increasing in size rapidly, the shoulder slope flattisli, situated 

 at the posterior third on the last whorl, the sutun- distinct but not 

 appressed; aperture ovate, the body with a light glaze, the outer lip 

 thickened, sharij-edged, tinged with orange color; the type has eight 

 small denticles within on the callus; canal short, open, slightly re- 

 curved; general tint of the type f.pecimen dark, livid, olive color; 

 operculum muricoid. 



Height of sliell 21.5. of last wliorl IH.O, of aperture excluding the 

 canal 10.0; max. diameter of the shell 11.0, of the aperture 6.2 mm. 



The animal, like that of the other species, is [lurpuriferous. It 

 presents a strong contrast to the other species of the genus in its 

 general smoothness and absence of conspicuous sculpture and the 

 bright color of the lip.
