ON A NEW GENUS AND TWO NEW SPECIES 

 OF MACRUROUS CRUSTACEA. ^ 



BY J. S. KINGSLEY. 



1 owe to Professor Hermon C. Biimpus, of Brown Uni- 

 versity, the privilege of examining a small shrimp which 

 he obtained from the Island of Naushon, one of the Eliza- 

 beth Islands, on the sonthern coast of Massachusetts. 

 Under ordinary circumstances the publication of isolated 

 descriptions is to ))e deplored, but in this case the pro- 

 cedure seems to have some justification. In the first 

 place the whole Vineyard Sound region has been so thor- 

 oughly explored by the various parties of the U. S. Fish 

 Commission and by the members of the Marine Biologi- 

 cal Laboratory at Woods Holl, that novelties among the 

 Deca[)()d Crustacea are extren»ely rare. Again, the form 

 in (jtiestion is unique in several of its features, combining 

 as it does the cliaractcrs of seveial other orenei'a or even 

 of so-called families. 



The specimen, which is the basis of the following de- 

 scription, was found July 13, 1893, in the sand of the 

 small channels — the so-called gutters — ot the island. 



Genus Naushonia. Body somewhat depressed; mandi- 

 bles stout, incurved, the cutting edge excavate anteriorly, 

 the edge itself serrate ; a two-jointed palpus present.
