450 DR MUKKAY ON THE DEEP AND SHALLOW- WATER MARINE FAUNA 



The foreo-oing euumeration (List V.) of species recorded from Kerguelen, from sources 

 other than the Challenger Expedition, includes aliout 112 species belonging to about 87 

 t^enera. Some of these species require verification, but looking upon them for the present 

 as authentic, and adding them to the Challenger List (List IV.), we should have a total of 

 645 species of Metazoa, belonging to 371 genera, recorded from the shallow waters of the 

 Kero'uelen Region in depths not exceeding 150 fathoms. The proportion of genera to 

 species would thus be as 1 to 174, while the proportion of genera to species in List 

 IV. is as 1 to 1'64, due to the fact that, while all the species in List V. are distinct from 

 those in List IV., about half the genera in List V. are already included in List IV.
