List of stations. 



As in the two other subspecies, torvus and aeger, the posterior lens- 

 like organ, which is located immediately in advance of the anus, is 

 transversely elongate and bilobed, being almost dumb-bell. shaped. 



The orbit in this, the typical subspecies, is large and almost ex- 

 actly circular in outline, the oblique diameter being about equal to the 

 vertical diameter. 



The ventral rays are constantly 8 in number; the only varying 

 specimens are 2 from near Formosa, which have 8 rays on one 

 side, 9 on the other. 



(striatissimus, in reference to the extensive development of the 

 abdominal striation.)
