Sharepoint Rest: Get library url

I managed solve the url thing by creating it manually like this:

hostweburl + '/' + this.Title

But I noted another problem:

In the site I have created 2 libraries "test" and "test2" but in the result, besides this 2 libraries, I am also getting system libraries like "MicroFeed", "appfiles", "appdata", etc. 

I there a way to filter this system folder out? 

This is how I am sending my request:

url: appweburl + "/_api/SP.AppContextSite(@target)/web/lists?@target='" + hostweburl + "'"

and later I am using this:

$(results).each(function () {
 items.push('<li class="element">'
     + '<a target="_parent" href="' + hostweburl + '/' + this.Title + '">' + this.Title + '</a>'
     + '</li>');
});

Any tips??
