" Differs from B. contrarius and B. loevus Mi.il!., by its angular 

 aperture, and the color of its lip and throat. The interrupted line 

 just in front of the suture, exists in all the specimens I have seen. 

 It does not always occur reversed. Compare B. theobaldiamis " 

 (Gld.}. 



The identity of moniliferus (fig. 73) with theobaldianus (fig. 74,) 

 hinted by Gould, Pfeiffer, and the authors of the Concholoyiu Judtoi, 

 is confirmed by Fulton. It is a smaller shell than others of the jjroup. 

 Dr. von Mollendorff reports a single dead specimen which set-ins to 

 agree with this species, from the Samui Islands, near the neck of the 

 Malay Peninsula on the east side. 



A. moniliferuf evidently stands near A. glaucolarynx. 



A. GLAUCOLARYNX (Dohrn). PI. 60, fig. 49. 



Shell (dextral or sinistral) rimate, ovate-turreted, rather thin, 

 smooth, buff under a corneous cuticle, broadly streaked and bunded 

 with blue-broivn or purple-brown. Spire conic, rather obtuse, purple, 

 rarely livid; suture submargined, broadly encircled with white. 

 Whorls 6 to 7, a little convex, the last three-ninths the total length, 

 the base subangular and encircled by a wide straw-colored band. 

 Aperture oblique, semi-oval, effuse at base, violaceous witltin ; peri- 

 stome expanded, violaceous, the margins joined by a thin callus 

 (Dohrn'). 



Length 45, diam. 17 mill., aperture 17^ mill, long inside (Dohrn).
