Murex Veatchi, n. s. 

 PL VI, fig. 7. 



Shell pyriform, small, with five somewhat convex whorls, 

 transverse sculpture of numerous, prominent raised lines which 

 show some tendency to alternate but in general are sub-equal, 

 longitudinal sculpture of sub-equal varices (six on the last whorl) 

 and of fine longitudinal raised lines which form with the spirals a 

 ver} r fine network, or honey-comb ornamentation. Aperture 

 oval ; canal open ; outer lip lirate within. Length of shell 21 ; 

 of aperture and canal 13 ; greatest width 12 mm. 



Named in honor of Mr. Arthur Veatch of the United States 

 Geological Survey who collected the shells.

Trivia chipolana, n. s 

 PI. VI, fig. 8. 



Shell globose, inflated, rather thin, ribs fine, numerous, 

 about twenty-five on the lip where they form a line of fine but 

 sharply-defined teeth. The ribs extend uninterruptedly over the 

 dorsal area of the shell and occasionally divaricate towards the 

 lateral margins. The shell shows a very faint medial dorsal 

 ridge with barely visible grooves on either side. Length of shell 

 7.5 ; greatest width 5 ; height 5 mm. 



It is interesting to note that this species from the Florida 

 Oligocene is very like small specimens of T. Europcza Montagu 

 from which it differs only in the faint dorsal groovings which are 

 absent in the Europsean species. T. Europcea ( T. sphezrlculata 

 Lam.) is found in the Miocene abroad being common in the Red 

 Crag. Its present distribution is from the Mediterranean north 

 along the continent to Norway. This species appears to be the 

 nearest ally of the Chipola shell.
