Of this and the next species Krauss says: " I found both 

 species on a whale stranded in Table Bay."

Bate says: "The figure and description are taken from a 

 specimen from the Cape of Good Hope that was entrusted to 

 me from the Jardin des Plantes." He also gives White as an 

 authority for the occurrence of the species on the British 

 coast. Liitken at first discredited this, but later admitted its 

 possibility.

This species, sent by Dr. Peringuey, was obtained from the 

 head of Balcena australis, at Cape Town. It has the branchial 

 vesicles doubles, which in the male are accompanied by acces- 

 sory appendages, single on the first pair but double on the 

 second. The third thoracic segment in the male is laterally 

 produced both forward and backward, the following segment 



only backward.
