172 REPORT—1883. 
The minute details furnished by Busk in his diagnosis compel me 
to place this species here, temporarily at least. Is this, however, 
synonymous with Haime’s species ? 
Locality—Lower Greensand, Farringdon. 
HETEROPORA sp. 
As referred to previously there is present in the Greensand of 
Haldon Hill, Devon, a species very similar, in external characters, to 
Entalophora pustulosa, only that the orifices of the cells are smaller, the 
intermediate spaces are pitted, and the interstitial openings few in 
number. Hight cells occupy the space of a line in a longitudinal direc- 
tion. 
Locality —Haldon Hill, Devon (collected by Miss Jelly). 
HETEROPORA TENERA, Hagenow. 
= Ceriopora cryptopora (pars), Goldfuss, 
In the Lower Greensand, Farringdon, and also the Upper Greensand, 
Warminster, is a delicate species of Heteropora which Morris catalogues 
as H. tenera, Hagenow. There is but little difference in the structure of 
this species and the larger H. crassa, Hagenow, which is selected by the 
author from Goldfuss’s as his type. Goldfuss includes the large and 
the small in his O. eryptopora, but Hagenow divides the honours and 
founds two types upon the one form. It is best, however, to refer to the 
labours of Hagenow, because if ‘form &c.’ were a character on which 
species could be accepted, the labours of this distinguished Paleontologist 
would prove of great advantage to the systematist. Hagenow’s species 
are H. crassa, Hag., H. dichotona, Goldf., H. undulata, Hag., H. tenera, 
Hag., H. Dumonti, Hag. 
In giving descriptions of American Cretaceous Heteropora Mr. Ulrich 
remarks (‘Amer. Palzoz. Bryozoa’ (Cin. Soc. Nat. Hist. p. 143, 1882) 
that ‘the species from Arkansas is nearly allied to Zonopora variabilis, 
D’Orb., from the Cretaceous of France.’ The other species which the 
author describes and figures are H. consimilis, Ulrich, and H. attenuata, 
Ulrich. 
Sub-order Cueitostomara, Busk. 
Our British Cretaceous Cheilostomata are very limited in the number 
of species, but I believe that if a diligent search could be made our lists 
would be added to considerably. Prof. Morris in his ‘ Catalogue’ gives 
only thirteen species, and 1 am unaware of the existence of any further 
additions to this list by British authors. In his Division D, URcEOLATA, 
Hagenow catalogues five species of Vincwlaria, fifty- four species of 
E'schara, three species of Siphonella, Hag., thirty-three species of Celle- 
pora (Goldf. and Hag.), one species of Stichopora, Hag., two species of 
Lunulites, and five doubtful forms. A richness which we should be 
unable to boast of under the most careful researches—I fear so at least. 
Genus MempranrporA, Blainyille. 
= Flustra (part); Cellepora (part), Hagenow ; Marginaria (part), 
Roemer and Hagenow ; Dematopora (part), Hagenow. 
‘Zoarium encrusting. Zowcia quincuncial or irregularly disposed, 
occasionally in linear series, margins raised, front depressed, wholly or in 
part membranaceous.’—‘ Brit. Mar. Polyzoa,’ p. 128.
