should be of first order in general. However, the superconducting transition observed in $B < B_{\rm lcp}$ is of second order, and it is difficult to explain the presence of $B_{\rm lcp}$ consistently with the argument favoring the BrG phase. As far as the lower critical point is unrelated to the BrG melting, there is no reason why all of the thermal first order line in $B_{\rm lcp} < B < B_{\rm ucp}$ is included in the BrG melting line. Through some consideration including the above statements, we have concluded that a generic 3D phase diagram in ${\bf B} \perp$ layers with intermediate strengths of fluctuation and pinning will be of the form Fig.3 (a), in which the BrG melting is separated from the thermal first order transition occuring along $B_m(T)$, and the vortex slush regime exists entirely in $B_{\rm lcp} < B <  B_{\rm ucp}$. An evidence of a BrG melting line lying much below $B_{\rm VG}(T)$ was recently found in data of NbSe$_2$ \[49\] and (K, Ba)BiO$_3$ \[50\]. However, in HTSC with strong fluctuation, the thermal first order line may be pushed down to lower temperature and, in part, merge the BrG melting line. Then, the only possible
