» Mr. Ellis's "History of Zoophytes" is giveii a figure ot whatthe 

 » author regardée! as the Polype oîA . spiralis, which he found scat- 

 » tered over the stem of that species in the shape of small distant 

 » warts. Thèse when soaked in water, he describes as having six 

 » tenlacula surrounding a small ciip. The tentacula, he observes, 

 » in a letter to Linnœus, pubUshed in the "Gorrespondence" 

 » of that naturahst, are shaped like a bull's horns, with wrinkles 

 » across, and full of gelatinous matter ; and the cup of a most 

 » élégant figure. In the figure this part appears to be concave, 

 » with a crenated edge, and placed on an urn-shaped pedicle. 

 » Should this account of the Polype of Ant. spiralis prove to be 

 » correct, it would be necessary to remove that species from 

 » neighbourhood of the Gorgoniœ and other barked Corals, 

 » from ail of which it would differ so remarkably in its cup- 

 » shaped appendage, and the want of ciliation of the surface of 

 » its tentacula. Mr. Gray added that he had repeatedly examined 

 » the stem of the species in question, but had never been able to 

 » discover on it anything resembling a Polype. The earlier 

 » observations of Rumphius, Marsigli and Pallas, the former on 

 » Ant. spiralis, and the two latter on Ant. dichotoma, were of 

 » too vague a character to furnish any idea of the Polype (1). » 



M. Dana (2), dans son magnifique ouvrage de l'exploration 

 scientifique de l'Amérique, a donné des dessins fort beaux de 

 deux espèces, de VAntipalhes arborea et de YAntipathes anguina. 

 Gette dernière espèce doit très-probablement entrer dans le 

 genre Cirripathes de Blainv.. D'après les formes extérieures, 

 l'auteur américain a cru devoir établir un rapprochement entre 

 les Zoanthaires et les Ântipathaires, comme on peut en juger par 

 le passage suivant : 



« An examination of the animais of two species has led to an 

 » arrangement of them among the Actinoïdea, as the tentacles
