Issues copying a bucketfile to local disk

I've ran through the entire sequence that I believe I needed to do, but I am still getting an invalid argument type error while trying to copy my file locally. What am I doing wrong here?

vagrant@dev:~$ aws s3 ls s://bucketname-vagrant

A client error (NoSuchBucket) occurred when calling the ListObjects operation: The specified bucket does not exist

vagrant@dev:~$ aws s3 ls bucketname-vagrant

2015-03-30 13:55:01  102642228 or_vagrant.sql.xz

vagrant@dev:~$ aws s3 ls bucketname-vagrant/or_vagrant.sql.xz
2015-03-30 13:55:01  102642228 or_vagrant.sql.xz
vagrant@dev:~$ aws s3 cp bucketname-vagrant/or_vagrant.sql.xz /tmp/

usage: aws s3 cp <LocalPath> <S3Path> or <S3Path> <LocalPath> or <S3Path> <S3Path>
Error: Invalid argument type
