Graduate / Submitting documents by post for an online application [2]

Hi, I have a query, which I hope someone will be able to answer. I'm applying for a PhD online, but I need to submit certain documents by post. I am thinking about attaching a covering letter which will explain in detail what documents I am submitting, but I am not sure about its form. If the documents are to be submitted to 'Secretary of Graduate Studies' (it's general for the whole university, not for a particular department, so I don't know their name and they're also not somebody involved in selection, but rather responsible for the distribution of the documents), is the following form okay:
