ENTALOPHORA. 15.J 



Genus ENTALOPHORA, Lamouroux. 



Der. Named from the supposed resemblance of the zocecium to the shell 

 of Dcntalium entalt. 



EXTALOPHORA, Lamx. (1821): D'Orbigny: Smitt, Flor. Bryoz. 

 Pi-fTiLOPORA (part), Blainville (1834): M.-Edwards : Lamk. : Busk: &c. 

 Pi STULIPORA, Blainville : Johnston: Gray. 



GENERIC CHARACTER. ZOARIUM erect and ramose, rising 

 from a more or less expanded base, composed of decumbent 

 tubes; branches cylindrical. ZOCECIA tubular, opening on 

 all sides of the branches. 



ENTALOPHORA is nearly related to the section of the genus 

 Stomatopora in which the branches have a tendency to grow 

 upwards at certain points. In its young state it consists 

 of an adnate tubular crust. 



A question arises as to the name for this genus, though 

 one might think a glance at the dates as given in the syno- 

 nymy should settle it. Busk seems to admit that in strict 

 propriety Lamouroux's designation is entitled to prece- 

 dence ; but he thinks that to restore it under the circum- 

 stances would savour of pedantry (Crag Polyzoa, p. 107). 

 I confess it seems to me that the fewer departures from 

 the established rule the better. The accidental prevalence 

 of a much later name does not appear to be a reason for 

 retaining it. On the contrary, it may be a salutary vindi- 

 cation of the authority of the law to reject it after such 

 usurpation. The best cure for the disorders of our no- 

 menclature seems to be a rigorous application of the 

 principles which are generally accepted for its government. 

 Lamouroux's genus is characterized in a well-known work ; 

 and both diagnosis and figure arc sufficient for identifica- 

 tion : its claim seems to be complete. I shall therefore 

 follow D'Orbigny and Smitt in reinstating his name.
