James Protheroe Royal Navy

[red3]

Hi
Am trying to understand a record for James Protheroe who entered the Royal Navy as a volunteer on the 22 May 1871 on the "Fisgard"  (which I understand was a training ship at Woolwich)
 
James was born 22 May 1856 Westminster to Robert and Mary Ann Protheroe (of the Tavern "Adam and Eve" York St)

His Navy record from the National Archives records:
 
Ship                   Date                         If discharged whither and for what cause
 
Cambridge    1 Jan to 16 Jan 73
Impregnable 17 Jan to 19 May 73
Pearl            20 May to 2 Oct 73         Run Wellington
Blanche        20 Fed 74 to 7 April 74
Alacrity         8 April to 8 April  74      Run Auckland   Did not come for wages

These ships where in NZ and I can trace there movements on Papers past NZ.

What does Run Wellington and Run Auckland mean?
If he deserted his ship what could have become of him?  Could he have lived under another name for the rest of his life?
He was only 18 at this time.

According to his record he was 4 foot 11" , grey eyes, fair complexion and a tattoo on leg to waist and had no trade.

Any help would be appreciated.

Regards
