This species appears to be quite rare, only one specimen having 

 been obtained. It reminds one of C. haidingeri Zekeli, but dif- 

 fers from that species in the angle of the spire and the character 

 . of the transverse costa?. 



Locality. Shoal Creek, Austin. Texas. 



FUSIDAE. 



Genus FUSUS Lamarck. 



Fusus SIMONDSI n. sp. 



PI. XI, fig. 2. 



Dimensions. Length, 100mm.; breadth, about 30mm. 



Description. Shell elevated, turreted; whorls nine, rounded; 

 sutures well defined ; spire straight, conical, equalling about one- 

 half the height of the shell; angle 25; anterior canal long, 

 straight, deep; lip and aperture unknown; surface of whorls 

 ornamented with eight to ten transverse cpstse, which, with the 

 intervening spaces, are crossed by four to six prominent,

 less.
