. Forms of animal life; being outlines of zoological classification based upon anatomical investigation and illustrated by descriptions of specimens and of figures . n atp. 133 supra, G. R.

For the existence of blood-corpuscles in the pseudhaemal system, seeQuatrefages, Hist. Nat. Annales, 86^, i., p. 63, ii., p. 168, where Si/Uidea armata is stated to possess blood-corpuscles inthose vessels; and the statement as to Gli/cera made in theAnn. Sci. Nat., 1850, iii. 14, p. 288, appears to be withdrawn. For a statement as to their presence in the pseudhaemal systemof some other Annelids, see Claparede, Ann. and Mag. Nat.Hist., Ser. iii., vol. xx., 1867, p. 350, where Gli/cera is statedto be devoid of the vascular system in question. For the pro-priety, however, of classing Phoronis as an Annelid, as is doneat p. 138 sujira, see Allman, Fresh-water Polyzoa, pp. S^Sl, and Dyster, cit., p. 138. PLATE X.. °^^^ id Common Star-Fish.

The digestive andother viscera have been in great part removed from the interior ofthe two rays of the bivium and the ampullae d 2, and the ambulacra!ossicles k 2 exposed in situ.
