ri:i. \STKA i K.K. f!,.i,t,llfTrea, the Spiudle-Wood Tribe, a 

 natural order of Polypetalou* Exogens, consisting of shrubs or trees 

 principally found in temperate latitudes, and not abounding in either 

 the colder or the hotter part* of the world. They are found in 

 Europe, Asia, North America, and South Africa. They have simple 

 alternate or opposite leaves, a small number of perigynous stamens 

 inserted into a fleshy disc and alternate with the petals ; a superior 

 syncarpmis ovary immersed in the fleshy disc ; and a superior capstilar 

 or succulent fruit, with a small number of ascending seeds. The 

 order is not of much economical importance. A slight degree of 

 acridity is said to have been detected in some of the species. 

 Kwnymtu Europceut, the Spindle-Tree, the wood of which is used 

 for butchers' skewers, is the commonest European form of this order.

CELLARLEA, or CELLABIADJC, the second family, according to 

 Do Bjainville's arrangement, of the sub-class Polypiaria Mcmliranacrn. 



Animals hydriform, pniviiK-tl uitli very <li-licate ciliated teutacula, 

 separated, distinct, contained in oval flattened membranous cellules, 

 with a bilateral subteruiined crescentie opening ; usually provided 

 with a moveable cartilaginoii.4 lij>, forming by their lateral junction, 

 in one or two tiers or stage*, a cretaceous or membranous, limited, 

 diversiform, and fixed polyzoarium. OvicelU external, globose, above 

 the aperture of the cell 



This group corresponds pretty nearly with the Eidiarada:, 

 Pilot rada, and Ctllariada of Fleming, and the Kt char inn and 

 CtUeporinn of Ehreuberg ; it also includes part of the sub-order Clteilo- 

 tlomata, of the Polyzoainfuinlil,uUit,i of Mr. Busk's ' Catalogue of Marine 

 Polyzoa,' For further particulars respecting the structure of the 

 animal* and their habitations, reference must Lc made to PtjLYZiM, a 

 few only of the principal forms being here noticed. 



We shall notice here the principal generic forms of this group. 



1. LuHiililn. The number of species of this generic group, of 

 which until lately only a few fossil forms were known, has been 

 much augmented by the addition, not only of other fossil species, but 

 also of several recent ones. The latter have also afforded a mm li 

 more precise insight into the structure of the peculiar , 

 orium than it wag possible to obtain from the inspection merely of 

 fossil specimens. The division of the genus suggested by Lamourdux 

 seems to be sufficiently founded in nature to justify HA definitive 

 adoption so far as it goes ; and, in addition, a recent form described 

 and figured in the 'Voyage of H. M. S. Rattlesnake' would seem 

 to indicate the propriety of instituting a third generic or sub-generic 

 type. 



In all these forms the polyzoory, which is more or less regularly 

 circular, convex above, and concave or flattened below, present* cell* 

 of two kind* one set of which may be termed secondary or 

 accessory ; and it U according to the relative position of these cells 

 a* regards the others that the division of the genus is founded. 



In one case the secondary cell, which is then considerably smaller 

 than the other, is situated at the apex of the primary cell, immediately 

 above the aperture (Cupularia). In a second form any distinction 

 of size between the two sorts of cells is less or not at all obvious. The 

 two set* of cells however are very differently arranged from those in 

 the former case ; the secondary being disposed more or less regularly 

 in longer or shorter rows, alternate with the others, and like them 

 radiating from the centre (LunuliKe). Of the former of these forms 

 the Lunulite en Parasol of Defrance may be taken to afford a tpe, and 

 of the latter, L. radiaia. In the third form the secondary cells are 

 scattered more irregularly over the surface of the polyzoary. In this 

 case the secondary cell is also superior to one of the other kind. 



From the examination of recent forms it has been ascertained that 

 the secondary cell probably contains nothing more than a mass of 

 muscular substance for the movement of a vibratile spine or seta, of 

 various forms and structure, and which corresponds with the vibra- 

 culum, or moveable setose organ, which is found on several of the 

 Polyzoa, and particularly in the genus Scrii/iin-il/iii-in. 



The arrangement of the group therefore into three genera would 

 appear to be justifiable and convenient, namely, Lunulila, Cupularia, 

 and Selenaria ; which may be thus defined : 



Lunnlit's, Lamouroux. Polyzoarium circular or irregular, con- 

 vex above, concave or flattened beneath; cells arranged in eerie*
