 11 specimens, mostly rather small, were taken on the north 

 side of a sand beach, which, except at high water, joins Taboga 

 to a small island on its northeast side. The specimens had 

 corneous opercula, but unfortunately these were destroyed by 

 the rats, which entered one of the boxes on their passage around 

 Cape Horn.
