Titles in Marriage Record

I came across my 2X great grandfather's marriage record, Anastacio Lopez and Urcina Arrieta. They were married in Jalpa, Zacatecas on September 4, 1836. I am wondering what the capital C stands for in front of his name and the MADAM or MADAME title in front of the bride's name. I noticed that the surrounding records do not have the same pattern.

Thank you for your help!
