1 General distribution patterns are given for each taxon: 



+ = taken 2 to 28 km offshore 



- = taken 37 to 1 1 1 km offshore 



c = coastal type ( >80% of all larvae taken 2 to 28 km from coast) 



o = offshore type ( >80% of all larvae taken 37 to 1 1 1 km from coast) 

 c-o = neither c or o type (<80% of all larvae taken in either coastal or offshore area). 

 2 The sum of the standardized numbers (number under 10 m 2 sea surface) of larvae from each sample in the coastal (2-28 km) and offshore (37-111) km 

 assemblages (139 and 148 samples, respectively), 

 identification based on one partly mutilated specimen.
