In connection with the apparent affinities of the Cape species 

 with tliose of the North Atlantic it should be noted that this 

 species is said by Mr. Sladen to be " nearly allied to Liiuiia sarsii 

 of the North Atlantic," and that, further, he recognised it from 

 a locality 35° north of the Equator. A series of forms from 

 intermediate localities may show that the species should be 

 united."*

1 ill now this species has been regarded as very rare ; the 

 specimen described by Gray in 1847 from Port Natal had no 

 companion till 1898, when the Government Biologist sent one 

 specimen from False Bay ; one specimen was collected by Pro- 

 fessor Studer in 117 fathoms south of the Cape of Good Hope. 

 The species is now well represented, and is found to grow to a 

 good size.

* It may be noted that the author of the above quoted sentence .goes on 

 to say "of which it is unquestionably the representative." If by this the 

 taxonomic representative is meant. I submit it is tautologous, and so an offence 

 against style ; if bionomic representative is meant, it is to be regretted that 

 evidence was not given in place of the always suspicious-looking word 

 ' unquestionably."
