Original description: — "Testa anguste umbilicata, globoso-sub- 

 turbinata, spiraliter 5-6 obsolete carinata, f'erruginea, versus 

 apiceiii rubeiite, oblique rugulosa ; spira conoidea, apice obtusi- 

 usculo ; anfractibus 4| convexiuscMilis, ultimi peripha^ria obsolete 

 angulata ; apertura auipla, vix obliqua, circular!, superne angulata ;

Nevill ivo;ai'ded the present species as a variety of C. hirna- 

 layanam, Pfr., but Benson, while admitting near relationship, 

 considered the two forms distinct. The latter is more depressed 

 and has a wider umbilicus. Pfeiffer, on the other hand, classed it: 

 as a variety under C. stenomphalus, but the figure in Conch. Icon., 

 which illustrates one of Benson's specimens, does not bear out 

 this view. 



82. Cyclophorus bapuensis, Godwin- Au.<ten.

 ■ Mus. viii, 1915, p. 494, pi. 38, fig. 2. 



" The description of this species follows that of sidiensis in many 

 particulars, but it is not nearly so keeled. It has a distinct peri- 

 pheral band. The umbilicus is more open and not so concealed. 

 The spire is lower, sides less flat, and first three whorls much 

 smaller. Suture more impressed. Whorls, aperture, and peri- 

 stome the same.
