The Porifera collection of the Zoological Survey of India is unique, as it is the largest collection in Southeast Asia. This is the first effort to prepare a catalogue of the marine Porifera type holdings. This catalogue includes type specimens of 20 species of Hexactinellida and 122 species of Demospongiae.
In this Paper, the taxonomic sequence of classes, orders and families follow Hooper and Van Soest, (2002) and Van Soest, Boury-Esnault, Janussen and Hooper (2008). Genera and species are arranged alphabetically within each higher classification. The type specimens belonging to the categories of holotype, paratype, co-type, type, schizotype and part of type whichever mentioned in the type label are mentioned accordingly. For each type specimen, the original name, authority (with reference), registration number, nature of type (as mentioned in the label of the specimen), type locality, current systematic status, current name (when status is changed), collector/donor and remarks are provided.
