O.N FOSSIL POLYZOA. 261 



Entalophora cellaeoides, Lamx. (Pustulopora, Nicholson.) 

 Plate ix. fig. 8, a. b. Haime's 'Jurassic Bryozoa.' 



This species is described by Haime as above. It is very different from 

 any of the Spiropora described by him, and he says that an ' incomplete 

 example was furnished to him by Walton, procured from Hampton Cliff.' 

 I am not acquainted with the type. 



Judging from the figures given by Nicholson (p. 430, ' Paleontology,' 

 vol. i.), this is a true Entalophora, well deserving of separate recognition. 

 Under any circumstances it could not be confounded with Spirupora. 



Fam. III. HoRNEEiD^. Hincks. 



This family contains only one genus, Hornera. There is no repre- 

 sentative of the family, in Brit. Jurassic Rocks at least, and I am not aware 

 of any recorded species of the genus in Foreign Oolites. As the Rev. Thomas 

 Hincks says that ' the genus Hornera is connected with Tubuliporidj:, 

 through Idmonea,' to which it bears in many points a very close resem- 

 blance,' in all probability early types of the genus, as defined by him, 

 may yet be found in either the Jurassic or Cretaceous rocks. The Sipho- 

 dictyum, of Lonsdale, is given as one of the synonyms of Hornera.^ 



Fam. IV. LiCHENOPOBiD^. 



This is the last family given by Hincks in which Jurassic Polyzoa can 

 be placed. The genus Lichenopora of Defranc has also a number of 

 synonyms, but as species of the genus are rare in the Oolites, we find 

 only one recorded. Haime says the genus has not been represented until 

 now, other than by Tertiary or Cretaceous fossils. In Lichenopora 

 PhiUipsii, dsrived from the Great Oolite of Hampton Cliff, the zoarium is 

 disciform, very slightly elevated, and adherent only by the middle of its 

 inferior face. The upper surface resembles a fungus, with unequally 

 developed rays formed of a series of long zooecia, ordinarily doubled. The 

 peristomes are polygonal, regular, and closely connected. 



Species of the genus, in all probability the same as above described, are 

 found in the Inferior Oolite, but too indistinct for description. 



Another peculiar genius of Lamouroux's is accepted by Haime — 

 Apsendesia — in which to place two species of Jurassic Polyzoa. In his 

 synoptical arrangement of the Polyzoa Cyclostomata, Busk places this 

 genus in the family Theonoidje : ' Zoarium massive sub-globose, or 

 irregular; zooecia contiguous crowded.' Haime describes in the foreign 

 Oolites two species — A. cristata, Lamx., and A. clypeata, Lamx. I 

 have no means of studying these, but Professor Braun, in his paper, places 

 as the synonyms of Apsendesia — Defrancia and PeJagia. In his descrip- 

 tion of the i'ascictdaria of the Crag — one of the genera of THEONOiPiE — 

 Mr. Busk places Apsendesia (pars), Blainville ; questioning its affinity 

 with Lamouroux's type, as one of the synonyms of the Fascicidaria of 

 Milne-Edwards. Facially the specimens of Lichenopora found in our own 

 Oolites may bear some resemblance to the figures of Haime, but as there was 

 some confusion in the mind of Blainville when drawing up the characters 

 of the genus Apsendesia, the student will do well to refer to the ' Crag 



' Brit. Maiine Polyzoa, vol. i. p. 467. * Hid.
