   Why does

   (defun test-buffer (the-buffer)
     (interactive "bTest buffer: ")
     (message "buffer: %s, sequencep %s, bufferp %s"
	      the-buffer (sequencep the-buffer) (bufferp the-buffer)))

   report that its arguement is a sequence and not a buffer?  

Because it's a string, the name of the buffer.

read-buffer:
One arg PROMPT, a string.  Read the name of a buffer and return as a string.
Prompts with PROMPT.
Optional second arg is value to return if user enters an empty line.
If optional third arg REQUIRE-MATCH is non-nil, only existing buffer names are allowed.
