Genus Scalpellum, almost as old as Podlicifes, but not quite, not being represented in the 
Lower Oolite; it is represented by numerous species, however, in secondary and 
tertiary strata. Number of recent species very large, at least 125 being at present 
known; distributed through all the seas and oceans of the world. Bathymetrical 
distribution a very wide one: the different species range from the coast down to 
the greatest depths inhabited by Cirripedes (4 5000 m.). 
Genus Verruca. The oldest known species dates back to secondary times. A species that is 
still existing ranges from the Coralline Crag through different tertiary deposits. 
Number of recent species considerable, 36 being at present known. Found in all 
the seas of the world, being more numerous, however, in deeper water. Bathy- 
metrical distribution a wide one, ranging from the coast down to 3400 m., not 
quite so wide, however, as was found for the genus Scalpellum. 
Genus Lalanus. The earlier species appeared during the deposition of the Eocene beds, no 
secondary species of this genus being known. Species very numerous in tertiary 
formations. Number of living species very considerable: more than 7o being at 
present known. Distribution all over the world’s surface, numerous species inhabiting 
tidal rocks, coastal and shallow waters. Some go down into a’ more considerable 
depth, a few only are true deep-sea species. The greatest depth inhabited by a 
species of Lalanus was found to be 564 m. 
To close this introduction, the following list enumerates the Stations where species 
of Cirripedia were collected, indicating the place of the Station, its depth and the 
character of the bottom, and mentioning the name of the species that were collected. 
Places between the stations where Cirripedia were collected during shore-exploration are 
mentioned in the list.
