EUCRATIADiE : GEMELLARIA. 293 



right angles to the cells, from the sides of the apertures. The aper- 

 tures are rather small, and, as usually seen, are round, even, and 

 unarmed ; but, in recent and living specimens, they are long and 

 tubular, frequently as long as the cell. In this state it may be 

 taken for a species of Tubulipora." B. Q. Couch. 



The fossil Crisia Johnstoniana of Dr. Mantell (Medals of Crea- 

 tion, i. 285) belongs to this genus, but it is very distinct from any 

 of the recent species. 



11. Gemellaria,* Savigny. 



Character. — Polypidom plant-like^ suicalcareous, rather soft 

 and flexible when dry., much branched dichotomoudy : cells 

 ffeininate, exactly opposite, united hack to back with a thick 

 disseptiment, a joint above and beloto each pair. — Polypes 

 ascidian, with elongated tentacula : no gizzard.

Hab. " A few fathoms beyond low water-mark," common ; but 

 Mr. Landsborough has never found " the smallest scrap of it on our 

 western coast." 



* Formed from gemellus, double, and not from gemellar. I learn from the 

 'Nomenclator Zoologicus" that the name was conferred on the genus in 1826 ; but 

 I had doubts whether the work of Savigny in which it is characterised was ever 

 puUished ; nor can I say that my doubts are entirely removed, although aware that 

 copies of it have been placed in public libraries. The genus was subsequently 

 named Loricaria by Lamouroux, Notamia by Fleming, and Gemmicellaria by 

 Blainville.
