Callinectes ornatus Ordway 



Closely resembles C. sapidus, but distinguished 

 from it by having six front teeth instead of four. 



This crab has not hitherto been reported north 

 of Beaufort, North Carolina. However, the young 

 of this species now frequently occur in small num- 

 bers during the summer in southern New Jersey. 

 They may be looked for in the inlets and thorough- 

 fares, although they have also been found in Dela- 

 ware Bay (to 10 fathoms). No adult specimens have 

 been seen in New Jersey or Beaufort ; in New Jersey 

 it never reaches over 2 inches in length. The adults 

 are common from South Carolina to the West Indies 

 and in South America. Its nip is said to be more 

 painful than that of C. sapidus. 



Arenaeus cribarius Lamarck 



PLATE XXVI. Fig. 6 



Resembles a young Callinectes but easily disting- 

 uished from it by its color and design. It is light 

 brown or olive and is thickly covered with small 

 rounded white spots; it rarely reaches a length of 

 more than 2 inches. This is a southern species that 

 is rare north of Virginia. Its home is the deeper 

 water off shore but it is frequently carried to the 

 coastal waters or stranded on the beach. It has been 

 seen as far north as Vineyard Sound, Massachusetts.
