BIOLOGICAL SURVEY OF DOMINICA! 
8. The Intertidal Balanomorph Cirripedia 
By Arnotp Ross? 
The present study on the intertidal balanomorph barnacles of 
Dominica is based on incidental collections made during April and 
May of 1966 by Dr. Ernst Kirsteuer of the American Museum of 
Natural History and by Dr. Klaus Riitzler of the Smithsonian 
Institution. These collections are of considerable value largely because 
there have been no previous studies or mention of the Cirripedia of 
Dominica. Represented in the collections are: Chthamalus angusti- 
tergum Pilsbry, 1916; Yetraclita (Tetraclita) stalactifera (Lamarck), 
1818; Tetraclita (Tetraclitella) divisa Nilsson-Cantell, 1921; and 
Balanus (Megabalanus) stultus Darwin, 1854. That this list does 
not embrace all the barnacles inhabiting this region is recognized, 
but it probably includes the more common species. 
All the Dominica species have been reported previously from other 
regions in the Caribbean and western Atlantic with the exception
