I.e. has stated that this name has been used in [844. for a genus of O/ra^/zb^zflfe^ by SChqenherr ; 

 LocARD agrees with Pilsbry in rejecting the name Olivia^ employed by Cantraine, as this name 

 was preoccupied by Bertholini in 18 10, for a genus of Sponges. The only recent species D. 

 Tinei Calcara was known from the Mediterranean and Adriatic Seas and the Gulf of Gascoene, 

 when in 1896 Dautzenberg and Fischer (Extr. des Memoires de la Soc. Zool. de France 1896, 

 p. 81, PL XX, fig. 9, 10) described a new species D. affinis from the Azores. As long as the 

 anatomy of this group is not known, I think it is better to consider it as a separate genus and 

 not as a subgenus of Euchehis, like Pilsbry has done ; indeed the strong varix of the outer 

 lip and the particulars of the dentition of the aperture, seem sufficient to separate it generically. 

 The latter calls in mind some species of Cla7ic%du.s rather than of Eiic/iehis. 



I. Danilia Weberi n. sp. PI. II, fig. 6. ' 



Stat. 105. 6°8'N., 121° 19' E. 275 M. Coralbottom. 6 Spec. 



Shell globose-conoidal, imperforate, thin, spire more or less elevated, embryonic whorls 

 wanting, remaining whorls about 6, very convex, especially the penultimate and ultimate ones, 

 the upper whorls forming a cone. Colour slightly variable, ground-colour light yellowish-brown, 

 nearly plain or with darker flames and blotches, which are always present on the varix, the 

 majority of the specimens has two or three series of darker spots on the upper whorls and two 

 specimens have a row of large blackish patches near the suture of the last whorl. The shell is 

 covered with a large number of spiral lirae, often with intermediate ones, the number of lirae 

 being about 7 on the penultimate whorl, but amount with the intermediate ones to 15 or 16; 

 they are crossed by numerous riblike striae, producing short spines on the points of intersection, 

 and very fine lines of growth; on the upper whorls the lirae diminish in number, they become 

 nearly obsolete on the uppermore whorls, and disappear at last, leaving only the concentric ribs. 

 The suture is deep, especially between the penultimate and ultimate whorls, on this last the 

 suture descends conspicuously. The periphery of last whorl is rounded, only apparently keeled 

 by the strong peripheral lira. The base is ornamented by about 1 2 beaded lirae, with ribbed 

 interstices. The oblique aperture is rounded-ovate, with a very thin, slightly expanded outer 

 and basal margin, encircled by a strong, compressed, external varix. The. margin is thickened 

 interiorly by a rather strong crenulated rib at some distance from the outer rim; the parietal 

 wall is covered by a much expanded, smooth layer, loosened from the body-whorl near the 

 place of the wanting umbilicus. The columella is very strong and tortuous, thickened above, 

 then slightly attenuated, with a strong square tooth, from which a tortuous rib runs to the left, 

 enclosing a triangular pit and forming a deep sinus between the columella and basal margin. 

 Interior of aperture very iridescent, but covered in part in the adult shells, by the porcellaneous 

 internal rib. , .
