"Differs from B. contrarius and B. Icevus Miill., 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. theobaldianus " 

 (Gld,). 



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

 hinted by Gould, PfeiflTer, and the authors of the Concholoyia Jitdica, 

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

 Dr. von Mollendorff reports a single dead specimen which sei-ms to 

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

 Malay Peninsula on the east side. 



A. moniliferus evidently stands near A. glaucolarynx. 



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

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

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

 (Dohrn). 



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