Superfluid density and heat capacity experiments on {sup 3}He-{sup 4}He mixtures in 98% porous aerogel show that in this system the coexistence boundary is detached from the superfluid transition line. The tricritical point is removed, and there is a superfluid phase on the {sup 3}He rich side of the phase diagram. The presence of heat capacity peaks along the transition line down to a {sup 4}He concentration of only 8% indicates the 3-dimensional nature of this transition.
