 Observation. Boule and Thevenin have refigured D'Orbigny's so-called types 



of this species, but unfortunately chose a specimen of Peronopora decipiens 



for this purpose. D'Orbigny's original description and Edwards and Haime's 



figures leave no doubt that the author of this species had this abundant 



Escharopora in mind.
