ON CRETACEOUS POLYZOA. 309 



30. Reticulipora complanata, Marsson, ' Brjoz. Weiss. Schreibkr 



Riigen,' p. 36, pi. 3, fig. 10. 



1821. Genus Entalophora, Lamourotix (see Perg., ' Revis. des 



Brjoz ,' p. 358). 



In Di-. Pergens' history and characteristics of this genus will be 

 found many details which may be valuable to the general student of 

 recent Polyzoa, as well as the fossil forms found in the Cretaceous rocks ; 

 but I question the value of the reduction of the ten species given by 

 d'Orbigny to mere synonyms of Pustulopora proboscidea, Edwards (1838), 

 (Perg., ' Revis. des Bryoz.,' p. 859). I cannot, however, wholly reject 

 the evidence brought forward by Dr. Pergens, who has liberally supplied 

 me — for comparison — with many beautiful examples of P. proloscidea 

 (Edw.), dredged from 60 fathoms off Capri, Bay of Naples ; also examples 

 from the Faxoe Limestone, Denmark, which were fully described in their 

 joint paper (Pergens and A. Meunier), 'La Faune des Bryozoaires 

 Garumniens de Faxe,' 'Ann. de la Soc. Royale Malacol. de Belgique,' tom. 

 xxi., 1886, p. 202). I shall, therefore, indicate by the word 'forma' the 

 abundant variety found in the Chalk of Chatham, at the same time givino- 

 the original references to the figures given by d'Orbigny in the ' Atlas.'

Pergens in his revision of d'Orbigny's labours re-establishes this genus. 

 See his remarks on the well-known species S. verticillata, Goldfass, I. c, 

 pp. 363-365.
