430 ON SPECIES OF HADENA SMITH. 



however, and the reniform is white marked. The tip of male harpe is 

 very like that of arctica, and the arrangement of spinules is similar, the 

 superior angle is somewhat drawn out and ladle shaped. The clasper 

 is very long and slender, extending beyond the end of tip. 



Occidens, with an obvious agreement of essential characters, is pale 

 gray in color, and the t. p. line is strongly retracted below the reniform. 

 Mr. Grote says that some specimens have the median space brownish, and 

 that the resemblance to arctica is obvious, but no such specimens 

 have been seen by me. The S has not been examined.
