Family PROCELLARID. 
This truly oceanic family is but feebly represented in the British 
seas, six or seven being all that we enumerate ; whereas with those 
frequenting the waters of the other parts of the globe they amount 
to double that number.

Furmar. 
Frequents the British seas generally. Breeds on the island of 
St. Kilda in countless multitudes. 
Genus PurFFINvs. 
Three or four birds of this form frequent the seas of the British 
Islands, two of which have been figured, and there can be no doubt 
as to the propriety of so doing; but I may state that there are 
others occasionally found here which are not well understood, or 
have not been properly worked out. Having myself collected these 
birds round the entire globe, I could not fail to remark the vast 
number of species I met with. In my ‘ Birds of Australia’ forty 
species are either figured or enumerated, and I feel assured that the 
list may be greatly added to on a closer research than I could 
give of the seas I had at that time (1838-41) the opportunity of 
traversing.
