XENOBALANUS 259 



The species was first found in the skin of porpoises (Darwin, 1854). By later authors 

 it is mentioned from whales and dolphins. In the literature I find the following hosts 

 for Xeuobolamis : 



Globicephala melaena (ace. to Nilsson-Cantell, 1921). 



G. intermedius (ace. to Pilsbry, 1916). 



Balaenoptera borealis (ace. to Nilsson-Cantell, 1921 ; Broch, 1924). 



B. physahis (ace. to Barnard, 1924). 



Tursiops catalania (ace. to Barnard, 1924). 



Delphinus delphis (ace. to Gruvel, 1920). 



Orcinus orca (ace. to Gruvel, 1920). 



Pseiidorca crassidens (ace. to Gruvel, 1920). 



Grampus griseiis (ace. to Gruvel, 1920). 



The Discovery material contains specimens from the following Cetaceans : 



Balaenoptera muscidus. 

 B. physahis. 

 B. borealis. 



The specimens were situated on diflferent parts of the host, for it is here noted from 

 the tail, tip of flipper, and the flukes. The largest specimen in the collection measures in 

 total length 36 mm.
