DIBAPHUS. 163 



M. EBURNEA, Garrett. 



Closely allied to M. Ancillides, but may be distinguished by 

 its ivory-white color, more contracted base, smaller size and 



more robust form. Length, 12 mill. 



Paumotus Isles. 

 I do not know this species ; it has not been figured. 



M. BELLULA, A. Adams. PI. 47, fig. 375. 



White, polished, with revolving striae, upper whorls cancel- 

 lated, a necklace-like row of reddish spots near the sutures. 



Length, -75 inch. 



Isle of Capul, Philippines ; on the reefs, low water. 



Described from a young and possibly abnormal specimen ; 

 may it not = Ancillides? 



M. TELUM, Sowb. PI. 47, fig. 376. 



Yellowish brown, lower half of body-whorl darker, smooth. 



Length, I'l inches. 



Mauritius. 



I have not seen this species. The figure is very like M. 

 mulliplicata (Barclayi], which also inhabits Mauritius, but the 

 columella does not show so many plications. 



M. INFECTA, Reeve. PI. 47, figs. 377-380. 



Yellowish, marbled with chestnut-brown, sometimes forming 

 two interrupted bands ; revolving striae inconspicuous or distinct. 



Length, 1*25-1 *5 inches. 



Mauritius. Paumotus. 



Sowerby says that Reeve's figure is erroneous, as it does not 

 show the revolving striae, and he gives another figure (fig. 378), 

 which differs somewhat in form and coloring. Reeve's -figure is 

 probably from a worn specimen Dohrn says, from the original 

 specimen of M. nebulosa, Swains. ; but nebulosa, as first figured 

 by Reeve, is a very different species and == M. ver&icolor, 

 Martyn. No doubt M. Barclay t, Hanley, not H. Adams, (figs. 

 379-380), is a synonym. 



Genus DIBAPHUS, Philippi. 



Differs from Mitroidea in the columella being without plaits. 

 It resembles in general form Gonus mitratus, as well as, more 

 distantly, Strombus terebellatus, and Adams, Crosse, and others
