did you extract it from the zip? That would be my first guess. My second guess would be you did extract the files, but with too much folder nesting. Namely it looks like starbound/girraffe_storage/mods/Uros IV (RAM's version)/ and within that are the folders Uros IV (RAM's version) - Apex Uros IV (RAM's version) - Avian etc. Those are the folders that should be in your mods folder directly. Starbound is looking for (whatever filename).modinfo and won't look more than 1 folder deep from the mods folder.
