propositions — a great superiority over the original work, where 

 they are given in copper-plates at the end of the book.

ANALYSIS OF PERIODICAL WORKS ON ZOOLOGY AND BOTANY. 



__ In our future Numbers we hope to devote a larger por- 

 tion of our attention to Zoology and Botany than we have 

 hitherto done, and give our readers an abstract of the contents 

 of such periodical works as relate to these two branches of 

 science. In the first, there are very few; but in the second, 

 the press is more prolific ; and from both we shall subjoin to 

 our report (for which we are indebted to able correspondents) 

 the characters of such new genera as have been proposed, and 

 such new species as are for the first time made known. 



Swainson's Zoological Illustrations. No. 23. 

 This work continues to support its high reputation, both on 

 account of its copious supply of new and interesting subjects, 

 and of the able manner in which they are illustrated by the 

 pen and pencil of the author. — To the ornithologist,, this is 

 a very rich number, as it contains four plates of birds, two of 

 which are new, and the others of species but little understood. 

 Trochilus ensipennis. T. aureo-viridis ; mento juguloque 

 cseruleo-violaceis ; rectricibus paribus ; alis fulcatis remigura 

 primorum scapis dilatato-compressis. — Habitat Amer. Merid. 

 Platyrhynclnts cancromus ; the female bird, a very curious 

 upecics, thus characterized: P. supra olivaceo-fuscus, infra 

 pallide fulvus; jugulo albo; genis pennisque spuriis nigris; 

 striga ante et pone oculum, maculaque auriculari albentibus. 

 Hab. in Brasilia. The other birds are : Ramphaslos tliculonis 

 and Miiscipda barbata. Mr. 8. appears to have paid much 

 attention to the generic characters of Platyrhynclnts and Mus- 

 cipcta Cuv. [Muscicapa Linn,), and I'rom his observations, it 

 appears these generic groups can only be separated by cha- 

 racters in some degree artificial. 



The only conchological subject, is the following new and 

 very beautiful cone. (a»ius pulclicllus .- testa aurantiaca, fasciis 

 albis interruptis ornata ; spirue subdeprcssa^, anfractibus su- 



turam
