I may be missing something but I can't work this out.

Ancestry lists the baptism of Mary Matthews, daughter of Thomas and Elizabeth, on the 11 April 1805 in Tewkesbury. When you look at the document it appears to be a bishops Transcript.
However when compared to the Tewkesbury parish register none of the names of those baptised in April match.
I thought that the document might refer to burials but they don't match either.
I can't fathom it out - I would be grateful if someone could have a second look for me. Thanks.
