Current status. Invalid.

Remarks. Fraser (1941b) designated material at the NMNHAbout NMNH as the “ type ” of Tubularia crassa  ( USNMAbout USNM 22746). The collection contains two specimens. One had been proposed as the lectotype and the other as a paralectotype of the species by K.W. Petersen in inter-museum correspondence, but the designations were never published and cannot be upheld as valid. The same designations are repeated here, with the lectotype having the original collection number ( USNMAbout USNM 22746) and the paralectotype being assigned a new number ( USNMAbout USNM 1458912).

The two original syntypes were also examined by Calder (1975), who concluded that they were identical with Corymorpha pendula L. Agassiz, 1862  . As with that species, the hydroids appear to be solitary inhabitants of soft substrates, hydrocauli are thick and parenchymatic, hydranths have smaller oral and larger aboral whorls of tentacles, and gonosomes are fixed sporosacs rather than free medusae (L. Agassiz 1862; Fraser 1944a). WoRMS currently lists T. crassa  as a taxon inquirenda.
