Bibliographical Notices. 149 lie given to the works of the present day, contains an immense mass of information, with descriptions of many of the birds which are now receiving names as entirely new. We must notice one little error in the second part. Speaking of Clangula Barrovii, it is said, " We believe only one specimen is in England, and it has hitherto only been found in the valleys of the Rocky Mountains ;" — a beautiful male specimen of this rare bird was shot some years since in Iceland by Mr. Atkinson ; so that its range is more extensive. The third part of the work, " Two centenaries and a quarter of birds either new, or hitherto imperfectly described," has no connec-tion with the first or second parts. The short specific descriptions are a little troublesome, from having the species mixed up together, and not generically arranged ; and it is less useful than it might be from the want of synonyms; for though many are new, many are also described and indicated in other works : for instance, Platyurus niger seems to be Scytalopusfuscus, Gould, Proc. Zool. Soc. for 1837 ; Ramphapis Melanogaster is the same with Lefresnaye's M. dimidia-tus, figured in the Magazin de Zoologie in the beginning of the last year ; Aglaia melanotis is very like D'Orbigny's Tanagra Schrankii, &c. ; Crypticus " Superciliosus," should be C. Super ciliaris, at least so Mr. Sandbach named it. Some of the birds again scarcely re-quire to be introduced as little known ; Le'istes Suchii, here called L. orioloides, has been at least twice figured, and several times de-scribed.

April. Zoology. I. Analysis of Fossil Scales from the old red Sandstone, Clashbermie, Perthshire. By A. Connell, Esq. The most curious fact in the ana-lysis of these scales is, that the ratio of the phosphate to the car-bonate of lime is in the proportion nearly of thirteen to one, and similar to two out of three analyses of recent fish-scales by Che-vreul. Of the animal matter there remained only a " trace." — II. On the organized bodies found in the mhia I fluid of Animals, and their analogy to the pollen of Plants. By G. R. Treviranus.

The paper en-deavours principally to establish the analogy between the fertilizing particles of the productive parts of plants and animals. — III.
