180 Bulletin, Vanderbilt Marine Museum, Vol. IV 



membraneous borders of the large suckers are covered with minute, 

 sharp, incurved teeth, smaller on the inner side; the suckers of the 

 lateral rows are comparatively large, deep, cup-shaped, very oblique 

 with the outer half of the horny ring cut into acute incurved teeth. 

 The membraneous borders of the large suckers are covered with 

 minute sharp chitinous scales. 



The pen is short, with the narrow part of the shaft short ; halfway 

 between the anterior end of the shaft and the blade proper, a thin 

 margin begins, increasing in width towards the blade which latter is 

 wide and thin with rounded lateral margins and the posterior end 

 obtuse. The surface of the pen is marked with thin divergent lines.
