fruit. They were seen in Corymbiferse, Cynarocephalese, and 

 Cichoriacese. In Pulicaria dysenterica, single oblong crystals with 

 angular pointed ends ; in Senecio Jacobaa and S. aquaticus, short 

 acicular crystals ; in Arctium intermedium and two other species, 

 cubical crystals ^^y inch diameter ; in Centaurea nigra, single 

 and double crystals shaped like those of Pulicaria ; in Carduus 

 lanceolatus, C.palusiris, and C. acaulis, some acicular forms and a 

 greater number like those of Pulicaria and Centaurea ; in Hypo- 

 chceris radicata, Apargia autumnalis, and Crepis virens, minute 

 square or cubical crystals. 



Dioscoreace/E. — Tamus communis < Raphides plentiful in the 

 stem and leaves, and still more so in the perianth and stamens. 



Orchidace^e. — The only species examined were Orchis M or io, 

 O. mascula, 0. maculata, and Habenaria chlorantha, in every 

 one of which raphides were abundant in all parts of the plant. 



IridacEjE. — Iris, Pseud-acorus. Long, prismatic, slender, and 

 blunt crystals, generally occurring singly, in the leaves. 



Liliace^e. — Endymion nutans. Raphides abundant in all 

 parts of this plant, from the perianth to the bulb ; though not 

 found at all in Allium ursinum. 



TypHACEiE. — Sparganium ramosum and S. simplex. Raphides 

 abundant in the perianth, fruit, stem, and leaves, though not 

 found at all in Typha latifolia and T. angustifolia. 



Araceje. — Arum maculatum. Raphides throughout the plant. 



LEMNACEiE. — Raphides (as described in Ann. Nat. Hist, for 

 May 1861) in all our plants, most abundant in Lemna trisulca 

 and L. minor, and comparatively scanty in L. polyrrhiza and L. 

 gibba. In L. minor the raphides (phosphate of lime) are plenti- 

 fully associated with starch-granules — thus indicating the valu- 

 able fertilizing and nutritious properties of this most common, 

 abject, and despised weed. 



III. — On the proposed Change in Name o/Gracula pectoralis. 

 By Alfred R. Wallace. 



To the Editors of the Annals and Magazine of Natural History. 



Gentlemen, 



May I be permitted to make a few remarks on Mr. G. R. Gray's 

 proposal (in the ( Annals ' for December 1862, p. 472) to change 

 the name of my Gracula pectoralis, described and figured in the 

 'Proceedings of the Zoological Society' for June last, into 

 Gracula Anais, that name having been given by Lesson to a bird 

 which Mr. Gray believes to be the same species. 



I am far from denying, or even doubting, that Lesson's bird
