LITTLE PIKED WHALE. 281 



of the intestine, which contained the long body of the parasite, firmly fastened at its head end 

 by hooks sunk into the fundus of each canal. 



Van Beneden (1859) has described a very large trematode or liver-fluke, Distoma goliath, 

 from specimens sent him by Eschricht found in the liver, and he himself found the same species 

 in a specimen captured in the Escaut in 1865. 



A species of Ascaris (A. angulivalvis) is described by Creplin from the intestine, and a 

 thread worm, Filaria crassicauda, is found in the urethral canal and in the corpora cavernosa 

 of the male. 



Of external parasites, Penella balaenopterae, an aberrant crustacean, is sometimes found, 

 particularly about the genital orifices. It was first described from a specimen taken from a 

 whale of this species captured on the coast of Norway (Koren and Danielssen : Fauna Littoralis 

 Norvegiae, 1877, part 3, p. 157, pi. 16, fig. 1-9). In its adult condition, the body is buried in 

 the flesh of the whale and the slender thoracic portion floats free for some eight inches (180 mm.). 

 A stalked barnacle, Conchoderma virgata sometimes attaches itself to the Penella.
