Figure 36. — Callinectes sapidus, male (carapace length 53.2 mm) from Dominica station 36. 



Material examined. — The Dominican collections contain 3 males 

 (carapace lengths in midline 19.3-53.2 mm), 2 females (cl 46.8 and 

 51.4 mm), and 1 juvenile (cl 6.2 mm). In the two smaller males (cl 

 19.3 and 22.4 mm), the abdomen is sealed to the sternum; the first 

 pleopods are nearly straight in both, reaching to the middle of the 

 sternite supporting the third pereiopods in the smaller specimen and 

 nearly to the suture anterior to that sternite in the larger. Only the 

 larger of the two females has the abdomen fully formed; it is subtri- 

 angular in the smaller female.
