MELANIIDiE. 217 



Agree exactly with Philippi's original figure, only a little 

 smaller ; they are, I believe, quite adult. 



Genus FAUNUS, de Mont/ort. 



Conch. Syst., 1810, type Strombus ater, lAn. ; =Pirena, Lam., 1822, 

 P. terebralis. Lam, \j=-F. ater] ;=MelaMamona, Bowditch, 



Operculum resembling that of Tanalia ; approximately one- 

 third of the internal surface is covered vrith a black polished 

 glaze ; externally there is a somewhat indistinct striation.

2 Celebes [?] ; ex c. Dr. F. Stoliczka [ex Landauer], 



More slender and produced than my Ceylon specimens, with 

 the last whorl not so broad ; colour jet-black. 



Long. 73, diam. 18|- mil. ; not decollate. They agree fairly 

 with M. Brot's pi, 44, fig. 3 [Philippines] ; it seems to me to 

 agree with Reeve's F. cantori, from Penang ; size is of little 

 importance. 



1 Philippines [?] j coll. Baron P. von Ricbthofen. 



A young specimen, in bad condition. 



5 Ceylon j ex c. Dr. F. Stoliczka. 



This I take to be the typical form ; they agree with M. Brot's 

 fig. 3 B. [var. ^ida, Rv.]. Long. 80, diam. 22 mil. 



1 Nicobars [?] ; ex c. Capt. R. C. Temple. 



Closely resembling the preceding, only rather smaller. The 

 locality is an important one, but requires confirmation.
