... are (of course) the names of the reserve boats of Oxford and Cambridge (in that order).
Isis is the name given to the River Thames in its Oxford section; John Goldie was President of Cambrige University Boat Club from 1870 to 1872, and the boathouse on the River Cam that the Cambridge crews use is named after him.
The Women's Boat Race was first rowed in 1927, and has taken place annually since 1964. Since the 2015 race it has been rowed on the same day and course as the men's Boat Race. The number of women rowers increased after 1964, as more colleges started to admit women, and reserve boats from each university began racing in 1966 (the year after the men's reserve boats began racing). The women's reserve boats were later named Osiris (Oxford) and Blondie (Cambridge). (In Egyptian mythology, Osiris was the brother and husband of Isis, who was of course female.)
