phases of growth. <u>O. angulata</u> being the youngest, <u>O. [text?] [text?]</u> the next in age, and <u>O. uncinata</u> the adult. He arrived at this result, of the truth of which I am myself well assured, by the comparison of a great number of spe- cimens, - a process which it would have been well for science if he had more constantly adopted. The name of the adult form should of course stand as that of the species; but the organism in question is more commonly known under the designation <u>Orbiculina adunca</u>, which seems to have been conferred upon it by M. Deslongschamps. <sup>1<sup> 79. A considerable number of figures of this species are given by M. D'Orbigny in his treatise on the Formaninifera of Cuba, which forms part of the great work of M. Ramon de la Sagra on the Natural History &c of that island. <sup>2<sup> These fi- gures, however, serve only to give a general idea of the vari- eties of external conformation which had presented them selves to him; and notwithstanding their number and va tiety, they do not include some of the most important among the protean shapes of these bodies, nor do they throw any light upon their internal structure. 80. The Memoirs of Prof. Ehrenberg <sup>3<sup> in which the group of Bryozoa was originally constituted, made the first approach towards a recognition of the true relationship between Orbi <u>tolites</u> and <u>Orbiculina</u>; of which the first had previously been ranked among the Zoophytes; while the second (until the Rhizopodous nature of the whole group of Foraminfera was made known by M. Dujardin in 1835) had been associated with the Cephalopods. Prof Ehrenberg's description and figures _ _ _ _ _ _ _ _ _ _ _ 1. Encyclopédie Methodique: Zoophytes : <s>by</s> Paris, 1824 2.
