1st Family. Beroid.e Esch. 1829. fO 



The true characteristics of the species of this family are 

 not yet discovered. Were the synonymy of some authors 

 taken for granted, it would follow that there are species 

 ranging all the world over, which cannot be admitted without 

 the most careful comparison. On the other hand the charac- 

 ters ascribed to the species observed in different localities 

 hardly justify their admission as true species. It is there- 

 fore necessary to await further information before considering 

 either the geographical distribution of these Acalephs, or their 

 specific limitation, as satisfactorily traced.

* I find it impossible to ascertain positively synonynies in 1829, and for which Lamarck, An. 

 whether the genera Callianira and Sophia, which s. Vert., seems to have the priority, really consti- 

 Eschscholtz represents as distinct in 182.5, and as tute two genera or not.
