Dareste on a Monstrosity of Delphinium Ajacis. — M. Bunge on the 

 genus Bray a. — Count Jaubert and M. E. Spach, a Monograph of the 

 genus Cicer : eight species enumerated. — Monograph of the genus 

 Halimodcndron, by the same botanists : three species described. — 

 Third Century (5 — 8 decades) of new Exotic Cellular Plants, by 

 Dr. Montagne. 



Nov. 1842. — Zoology. — Continuation of M. d'Orbigny's memoir on 

 the Belemnites ; the author arranges them under five groups : 1st, the 

 Acuari-, 2nd, Canaliculati; 3rd, Hastdti; Ath t Clavati', and 5th, Dilatati. 

 These divisions not only present good zoological characters, but are 

 respectively concentrated in different geological formations. — M. de 

 Quatrefages on Eleutheria dichotoma, a new genus of Radiata allied to 

 Hydra. Several highly original papers by this naturalist have lately 

 appeared in the ' Annales,' founded on researches among the Inver- 

 tebrata of the coasts of France. Most of the animals he has described 

 may be looked for in our own seas. The new zoophyte here fully 

 investigated is microscopic, and appears to us to be rather an ally of 

 Lucernaria than of Hydra, very possibly the young state of some 

 known species. The author has a tendency to see too much, and 

 to put too great faith in the description of Hydra by M. Corda. 

 His generic character, " Ocular points at the bases of the arms : no 

 feet," is insufficient and unphilosophical. — M. S. Lov£n on the Me- 

 tamorphosis of an Annelide, see ' Annals Nat. Hist/ vol. xi. p. 43. — 

 M. S. Loven on Myxostoma cirrhiferum : an excellent paper on the 

 curious parasite which infests the arms of Comatula. — M. Brulle on 

 the Classification of Animals in parallel series, concluded. — M. Flou- 

 rens on the Development of Bone. 



Botany. — M. Montagne on Exotic Cellulares, continued.— Count 

 Jaubert and M. Spach, Monograph of Chesneya. — Prof. Bernhardi on 

 the characters of Tulipacece and allied families (a translation from the 

 ' Flora' for 1840). — M. Desvaux on anew Fig and some plants fur- 

 nishing Milk. — M. Goeppert on the Anatomical Structure of some 

 Magnoliacece (from the ' Linnsea'). The researches of the author lead 

 him to deny the analogy asserted to exist between Tasmannia and 

 Drimys on the one hand, and the Coniferce on the other. The re- 

 sult is important, as removing an uncertainty from the study of fossil 

 botany. 



Dec. 1842. — Zoology. — Observations on the structure and func- 

 tions of some Zoophyta, Mollusca and Crustacea of the coasts of 

 France, by M. H. Milne Edwards. Every communication from the 

 pen of M. Milne Edwards is of great value. In this paper he gives 

 some most interesting notices : 1 . On the Hermaphrodism of Pectens 

 (in describing the testicle there is no mention of Spermatozoa). 

 2. On the Organization of Carinaria Mediterranea : the distinction of 

 sexes in the animals of this species is first made out. In describing 

 the respiratory system no mention is made of the presence or absence 

 of cilia on the branchiae, the structure of which is compared to that 

 of the branchiae of the Pleurobranchus. [We have sought for cilia 

 on the branchiae of Firola in vain, but with better glasses and under 

 more favourable circumstances they may perhaps be detected.] The
