As was the case with species of Sca/fellum, although mostly at other Stations, several 
places seem to be particularly attractive for species of the genus Balanus. Species of this genus 
were found at about 40 out of the 323 places or Stations, explored during the cruise of the Siboga. 
It happened no less than 8 times, however, that more than one species of Lalanus was 
collected at the same place or with the same haul of the dredge. These cases were the following: 
At Station 49°: B. maldivensts and B. maculatus n. sp. 
At Station 50: 4. amaryllis and B. amphitrite. 
In Molo Strait (about Station 51) B. célatus n. sp. and B. maldivensis. 
At Station 162: BL. amphitrite and B. socialis. 
At Station 164: £2. amphitrite, B. calceolus, B. cornutus n. sp., B. quadrivitiatus, 
B. quinguevittatus n. sp. and B. socialis.
