The history of the species which have been referred to Tervia is somewhat involved. 

 The genus was founded by Jullien, in 1883, for four species dredged in the' Atlantic. Two 

 of these species, T solida and T. discreta have been regarded by Morman j ) as forms of T. 

 irregularis Meneghini. In 1903 Jullien and Calvet'-) admitted that T. folini, one of the 

 species which had been included in the genus by Jullien in the original account was a synonym 

 of T. irregularis. 



In 1853 D'Orbigny 3 ) founded the genus Filisparsa for several fossil and recent species, 

 of somewhat varied appearance ; and his name has been accepted by certain later writers, as 

 by Gregory *) and Pergens 5 ). 



The character by which Tervia was distinguished from Idmonea in the original account 

 was that some of the zooecia are "isolées, disposées sans ordre sur Ie milieu des branches, 

 entre les séries latérales". This character by itself might not be considered a sufficiënt reason 

 for establishing the genus ; but it has been pointed out by Waters 6 ), in several places, that 

 the ovicell of Tervia irregularis is "dorsal" in position, while that of Hornera violaeea, var. 

 tubulosa, or H. tubulosa Busk v ), which he refers to Filisparsa, is situated on the front of the 

 branch. The "dorsal" ovicell of Tervia has been figured by Waters 8 ), Neviani 9 ) and Jullien 

 and Calvet 10 ).

 come from the North Atlantic, is preserved in the British Museum (75. 5. 29. 29). The oociostomes, of which two are well shown, have 

 a considerable resemblance to those of Ttibulipora apcrta\ and the widely open ooeciopores, facing frontally, are also like those of that 

 species. The zoarium is, however, composed of narrow, bifurcating branches, in which the zooecia are mostly scattered, with but little 

 indication of the formation of transverse series. It seems to me by no means improbable that the form which I described as Tubulipora 

 aperta is merely an adnate phase of Hornera tubulosa Busk; although the characters of the ovicell show that the latter cannot be placed 

 in the genus to which BUSK referred it.
