AURIS. 105 



All of the published figures cited in the above references represent 

 the var. swainsoni; typical chrysostoma being, we believe, illus- 

 trated here for the first time. In some large specimens of swainsoni, 

 the basal lip is much produced, like the lobe of the ear ; this being 

 shown in a specimen before me and in the figure of Fc'russac. The 

 coloration is more mottled in these than in typical chnjsostoma. and 

 shows a sparse sprinkling of small, intense brown round spots. 

 Specimens of both chrysostoma and sivainsoni are before me from 

 Bahia. 



A. BER-N ARDII Pfeifter. PI. 38, figs. 8, 9. 



Shell perforate, ovate-conic, solid and opaque, fleshy-white with 

 bold undulating brown longitudinal stripes, in places broken or dis- 

 located, and below the periphery interrupted by a pale band ; the 

 spire pale, without black spots between the folds, the apex white. 

 Surface sruoothish, but peculiarly sculptured by obliquely-descending 

 series of long granules (pi. 38, fig. 8) ; the base more densely granu- 

 late, the granules crowded as in A. illheocola. Whorls of spire 

 strongly plicate below the sutures, which are slightly crenulated. 

 Whorls 5 i. 



Aperture ovate, vertical, white within, with dark marbling cor- 

 responding to the external coloration ; lip broadly and rather flatly 

 reflexed, recurved, white, with a narrow yellowish outer edge ; 

 inner margin slightly thickened, but without a distinct rim or 

 flange. Columella oblique, straight, forming an angle with basal 

 lip but not notched at base. Parietal wall black. Alt. 60, diam. 

 34 mill. 



Province of Bahia, Brazil (R. Swift). 



Bulirnus bernardii PFE.., Malak. Bl., iii, 1856, p. 52 ; Novit. Conch, 

 i, p. 118, pi. 33, f. 3-5 ; Monogr., iv, p. 440. 



This species is the rarest form of the restricted subgenus Auris. 

 It differs from A. illheocola in color-pattern, sculpture, less lengthened 

 form and straight columella. A. bernardii is most nearly allied to 

 A. chrysostoma, differing from the typical form of that species in the 

 less developed hardly noticeable rim or flange within the lip, the 

 absence of any trace of a notch at base of columella, and the exten- 

 sion of black inward upon the parietal wall. A. bernardii differs 

 from A. chrysostoma var. swainsoni in the white lip and columella 

 and lack of a lobe on the basal lip; agreeing with swain so ni in 

 absence of the basal notch.
