This is a most interesting species, as numerous specimens show 

 great range of variation, and we also see how artificial our generic 

 divisions are, for I should have been justified in placing this under 

 Idmonea. It is probable that T. fasciculi/era, Hincks (Ann. & Mag. 

 Wat. Hist. ser. 5, vol. xiii. p. 35, pi. ix. fig. 6) is a variety of this 

 species ; and the unconnected colonies remind us of Reptofascigera 

 alternately d'Orb. ; while those that are continuous over a large 

 surface resemble Multifascigera Oampicheana, d'Orb. It is also 

 closely allied to Fasciculipora gracilis, MacG. ; but the very long 

 bundles of zocecia, connate for their greater length, show that this 

 last must certainly be looked upon as specifically distinct. 



A specimen from near Napier extends over a space of about 3 

 centim. across, and has extensive ocecial inflations, enclosing about 

 4 series, and wider than a ligula. 



A fine recent specimen from New Zealand, in Miss Jelly's collec- 

 tion, has the subcolonies widely flabellate, instead of strap-shaped, 

 and the spaces between the zocecia are, in places, divided into angular 

 or hexagonal divisions. The zocecia are usually uniserial, but 

 sometimes fasciculate. The small fragment from Port Phillip has 

 the zocecia close together without any space between.

The fossil from near Napier is one inch across, but is clearly 

 only a fragment of a large piece. u The horizontal, tabular, con- 

 centric lamina}" are nearer together than in the Crag specimen - y 

 but with this exception I see no difference. 



A recent T. tubipora in Miss Jelly's collection has a few funnel- 

 shaped openings on the lamina?. These may be ovicellular openings, 

 but a division across the narrower diameter raises doubts as to the 

 function. 



Loc. Living : New Zealand ? Fossil : C. Crag (B.) ; Bed Crag 

 (-5.); Pliocene of Rametto, Sicily (W.); near Napier.

The New-Zealand fossils are undoubtedly the same as the recent 

 forms found by the ' Challenger,' although smaller and with a variable 

 number of digitate lobes, averaging, however, about twelve ; the
