# caption of subfloat not fitting on page

In my thesis I have 13 figures I want on a single page. Since the last figure sits at the left side there is some space at the right side I would like to use for the caption. Somehow the caption goes below the figure and some part is chopped off. How can I make the caption use the right side of the last figure. Below is the code and the figure

\begin{figure}[htbp]
%\centering
\subfloat[\tiny\textbf{Ip, 0.00kcal/mol}]     {\label{fig:czar1p}\includegraphics[width=0.33\textwidth]{chap2/figs/czar1p.jpg}}
\subfloat[\tiny\textbf{IIp, 0.57kcal/mol}]{\label{fig:czar2p}\includegraphics[width=0.33\textwidth]{chap2/figs/czar2p.jpg}}
\subfloat[\tiny\textbf{IIn, 0.51kcal/mol}]{\label{fig:czar2n}\includegraphics[width=0.33\textwidth]{chap2/figs/czar2n.jpg}}

\caption{ The thirteen conformers of Cs\"{a}sz\"{a}r \cite{csaszar92} using MP2(full)/6-  311++G**. The nomenclature used here is adopted throughout this text for glycine. The representation p indicates that the heavy atom backbone C(=O)(CN)O is planar and n indicates they are nonplanar. The figure is the relative energy with respect to Ip}

I used a simple \parbox to place the caption (I used the demo option for graphicx to make my example compilable for everyone; do not use that option in your actual code):

\documentclass{book}
\usepackage[demo]{graphicx}
\usepackage{subfig}
\usepackage{caption}

\begin{document}

\begin{figure}[htbp] %

EDIT: I've modified my code according to Axel Sommerfeldt's comment.

This did not work as I want. As I said I would like for this figure alone the caption to fill the empty space on the bottom right. Thanks for the input though. –  Godey Apr 12 '11 at 22:03
Sorry it worked after I removed the \\ from the last figure. Thanks –  Godey Apr 12 '11 at 22:06
There is no need to use \captionlistentry and constucting the caption label for oneself, why not simply use \caption inside that parbox? –  Axel Sommerfeldt Apr 13 '11 at 5:44
@Axel Sommerfeldt: you're right and I've changed my code accordingly. I initially was considering another solution that forced me to buid the caption manually, but then I changed to a \parbox and forgot to make the necessary adjustments to the code. –  Gonzalo Medina Apr 13 '11 at 13:01
Thanks so much. you guys are awesome!!!! –  Godey Apr 13 '11 at 17:16
