 at low water) ; Cuming. 

 The chief peculiarity of this species consists m the 

 carious manner in which the widely expanded lip is re- 

 flected inwards at the side, and which is only slightly in- 

 dicated in any other. Although known to Liunanis, the 

 •S'. tatisaimus is still of rare occurrence.
