 Barbados (Franks Coll.). 



Notes. — Pectinia quadra ta seems to be clearly only a young form ; 

 P. elegans must go with P. quadrata. A certain amount of confusion 

 has been caused by Esper having included in his M. mceandrites two 

 different species : one (pi. iv. a) is clearly the type-form, but the 

 other (pi. iv.) has been generally regarded as a Manicina areolata ; 

 several later authors have taken the wrong form as the type, while 

 recently the converse error has been made.
