 Koch, also an Eutrochus). 



The shell is broader than high, rather thin, and of a pale 

 yellowish flesh-color, with fulvous blotches and flammules. The 

 whorls are transversely ridged and angulate at the sutures, and the 

 interior of the umbilicus is white. Mr. Cuming possesses but a 

 single specimen from Tasmania. (Ad.*) 



I hesitate to change the name of this, the typical species of 

 Eutrochus, but it is preoccupied by an undoubtedly congeneric 

 species, described years before. See under American speci s of 

 Eutrochus.
