1. PSAMMOBATIS RUDIS Gunther. 



Two young specimens from station 2770, in 58 fathoms. In the 

 youngest the dorsal surface is much rougher than in the other, 20 

 cm, in knigth. In the larger specimen the series of spines on the 

 dorsal side of the tail is beginning to show its triple character. The 

 tip of the tail is somewhat prolonged into a slender whip. 



A specimen 65 mm, long taken from an egg case with yolk sac 

 barely evident shows the tip of the tail stiU more prolonged to a 

 length equal to two-fifths of the remainder of the tail. The total 

 length of the tail from the ventral fins to its tip is three-fifths of the 

 total length of the specimen. The spines are barely evident, but 

 the body is otherwise t}^ical in its general shape. Tlie egg capsule
