Jade template: How to create a hyperlink in UL with description to the hyperlink

I'm trying to create a list with hyperlinks. Each list item contains a subject and a simple description to that subject in one line. I want to include a hyperlink for the subject but not the description. What I did is as below.

ul#subjects
    li
        a(href="#") Subject: Here is the description of the subject

The link works fine but it covers the whole line of text. How do I close the hyperlink so that it becomes something like below in HTML? Note that the ':' is not covered by the hyperlink.

<ul id='subjects'>
    <li><a href='#'>Subject</a>: Here is is the description of the subject
</ul>

Thank you. : )
