&c. The tender substance of flowers in ge- 

 neral appears to preclude the possibility of 



to which the term denticuli ought, perhaps, to be appro- 

 priated. We conceive, therefore, that the terms calathi- 

 form, cyathiform, &c. as above defined, will be found 

 particularly useful in distinguishing the catyculated sertu- 

 laria. It is, perhaps unnecessary to add, we have selected 

 the terms in question, from some proposed, by Mr. Salis- 

 bury, to be used in Botany, v. Linn. Trans. V. 5. p. 135. 

 Dentiform (dentiforme s. denticulus) tooth-shaped; small or 



pointed at the apex; not wide or large-mouthed. Sertularia 



Pinaster, T. 6. &.jilicula, T. 5. C. Ellis. 



Conical (conicum) having the form of a cone; broad and 

 round at the base, but gradually lessening to a point at the 

 aperture. 



Ovate (ovatum} egg-shaped, the apex being the smaller ex- 

 tremity. 



Oval (ora/c) egg-shaped, but with both extremities equal. 



Inflated (inflatum) puffed out, or nearly globular towards 

 the base, but suddenly becoming small and pointed at the 

 aperture. Sertularia filicula, T. 6. f. c. Ellis. 



Tubular (tubulatum) having the general form of a tube. 

 Sertularia halecina, T. 10. Ellis's Engl. Corall. 



&c. &c. The above terms, from h. are applicable to the 



genuine or distinct receptacle. The structure of the 

 spurious receptacle is only to be distinguished by those 

 terms which properly relate to the/orm of the aperture or 

 mouth, v. Osculum. 



The APERTURE of the receptacle (Osculuni) 

 i.^Qtbicufar (orbiculatum) circumscribed by a round or circular 



margin. Madrepora radiata, T. 47- f. 8. Ellis.
