 incerta in the western North Atlantic. 



3. Transatlantic province: (A) Virginian province (Cape Cod to 

 Cape Hatteras). No caprellid is restricted to this province, yet Cape 

 Hatteras does appear to be a southern barrier for the cold-water 

 species Aeginina longicornis and a northern barrier for the warm- 

 water species Phtisica marina. (B) Carolinian province (Cape Hatteras 

 to Cape Kennedy and Tampa Bay to the southern tip of Texas). 

 As in the case of the Virginian province, no caprellid species is re- 

 stricted to this area. If considered together the Virginian and Caro- 

 linian provinces can be characterized by species such as Paracaprella 

 tenuis and Caprella penanfis. The transatlantic province seems to 

 be an area of mixing of the Caprellidae with only 1 endemic form. 



4. Caribbean province (from Cape Kennedy and Tampa Bay into 

 the tropics, outer shelf to just north of Cape Hatteras, and Bermuda). 

 Many endemic species such as Fallotritella hiscaynensis and Hemiproto 

 wigleyi.
