Chylocladia articulata^ Phyc. Brit., is referred by 

 Agardh to his genus Lomentaria, and indeed it was on 

 pecies thai Lyngbye originally founded the genua 

 ia" a name which has precedence of Chylo- 

 cladia: but the genua now called Lomentaria by Conti- 

 nental botanists is typified by Ch. kaliformis, Ph. Br., and 

 to this vera! other exotic species belong, 



happens bo^i ever thai ( f h. articulata, as long since pointed 

 out by Dr. Greville, agrees in its fruit more nearly with Ch. 

 losa than with Ch. kaltformis. 1 consequently retain 

 it in Chylocladia. Ch. parvula is now removed from the 

 other British Bpecies, on account of a dissimilarity in its 

 fructification ; and J have referred it. together with >.
