in his genus are P. phalangca and P. flabellaris : - - both of them species which appear to 

 me congeneric with Tubulipora liliacea (= T. transversa, the genotype of Tubulipord). In view 

 of the enormous size of the genus Tubulipora, as I understand it (including the numerous fossil 

 forms) some subdivision may be desirable on practical grounds; but I am unable to see how 

 the adnate and erect conditions can be used by themselves in subdividing the genus into genera 

 or subgenera. 



It may be noted that Canu *) has proposed to abandon the genus Tubulipora, on the 

 ground that it has been used in so many different senses by various authors. For the adnate, 

 flabellate species referred to this genus by Hincks and others, he uses MacGillivray's genus 

 Liripora ~), which was, however, introduced for Diastopora lineata MacG. and D. fasciculata 

 MacG. : — ■ species which appear to belong to Bercnicca rather than to Tubulipora. 



I have accordingly referred most of the forms of Tubuliporidae obtained by the 'Siboga' 

 to the genus Tubulipora. The species commonly known as Idinonea radians appears to me 

 to deserve generic separation; and I have placed it in Crisina D'Orbigny. For one of the 

 other species I have employed Reptotubigera D'Orbigny. I follow Waters in referring species 

 of "Idmonea" with "dorsal" ovicells to Tervia Jullien. 



For the synonymy of species referred to these and other genera, Neviani's still 

 incomplete "Monografia del Genera fdmonea" s ) should be consulted. Lang*) has published a 

 recent summary of the Cretaceous species of "Idmoniidae".

Zoarium more or less flabellate, completely adnate. Primitive disc without denticulations. 

 Zooecia at the commencement of the colony strongly refiexed, the younger zooecia with 

 extremely long, delicate peristomes, which are mostly completely free in the centre of the 

 colony, but may unite in the marginal regions, where series of connate xooecia, 2 — 4 in 

 number, occur nearly at right angles to the edge. Ovicells of the typical Tubulipora form, 

 with numerous pores. Ooeciostomes free, with a more or less everted lip. Ooeciopores elongated 

 in one direction. 



MacGillivray (1. cit., Part VII) has described three species of Tubulipora from Victoria, 

 under the names T. concinna, T. pulchra and T. counala, all apparently nearly related to one
