OANTIIARUS. 157 



Morch has labelled specimens in our collection '■'■ C . ruhiginosus.'''' 

 The longitiulinal ribs are sixteen to eighteen in number. 



C. Menkeanus, Dunker. PI. 73, fig. 2(;4. 



Ribs yellowish brown on a white surface, eleven to fifteen in 



number ; a white band on the middle of the body-whorl. 



Length, -5 to '6 inch. 



Japan. 



A. Adams (Ann. Mag. V, 1870), identifies with this Engina 

 concinna.^ Reeve, but Lischke (Moll. Jap. Suppl. 50), points out 

 the great difterence between the two shells. The illustration 

 which I copy, is either a very poor one, or it is taken from a 

 worn specimen. I conjecture that it will be found to differ not 

 much from C. fumosiis var. rubiginosuK. 



C, Cecillii, Phil. PI. 73, figs. 262, 263. 



Longitudinal ribs six in number, which become true varices on 

 the body-whorl; yellowish to chestnut brown, the revolving strige 

 darker, frequently a white band Ijelow the periphery. 



Length, 28 to 38 mill. 



C'liiita ; Japan; Torres Straits. 



Turhinella Cecillii has not been figured, but the description 

 is unmistakable and has priority over Baccimuu ligneum.i Reeve 

 (fig. 262), B. baUealuin, Reeve (fig. 263), and B. Gumingianum^ 

 Dunker. Philippi described the species as a doubtful Turhinella 

 on account of the tubercles at the base of the columella, which 

 are transverse and oblique, somewhat resembling the plaits in 

 that genus. Frequently, the ribs become true varices on the 

 bodj'-whorl, which, with their smaller number and greater size 

 will distinguish them from C. erythrostonia. 



C. rusuujs, Brocchi. PI. 73, fig. 265. 



This mollusk, described seventy years ago as a fossil species, 

 has recently been found living in the Mediterranean Sea. I have 

 not seen it and have not access to the paper by Libassi, in which, 

 under the name of Sjxulce., it is redeseribed and figured. My illus- 

 tration is from Brocchi, and apparently resembles a Murex rather 

 than a Gantharus.
