which the Cirnex paradoxus is the type. Plate 3. represents the 

 transformations of Papilio Hector from General Hardwicke's draw- 

 ings ; and Plate 4. illustrates two species of a curious new genus 

 of Locusts. 



The plates of this work are drawn by the author himself, who has 

 been so long and well known as a delineator of insects. The figures 

 are drawn with much spirit ; although, in delicacy of execution, they 

 will not bear comparison with Mr. Curtis's beautiful work. Figures 

 of plants are also added, which give a more graceful appearance to 

 the plates. The work has our cordial wishes for its success.

We have much pleasure in drawing the attention of the lovers of 

 Natural History to this Journal, established in 1836 as an early and 

 frequent medium of publication for the researches and observations of 

 the naturalists of Denmark, and a vehicle of information relative to 

 those of other countries. The principal articles in the first volume 

 are the following : — 



No. I. Prof. Schouw, Nature in Northern Africa. — H. Kroyer, On 

 a new Crab, Geryon : — Scutum cephalicum longius quam latius, an- 

 tice arcuatum, postice truncatum, longitudinaliter valde convexum ; 

 frons latior, declivis sed parum arcuata ; margines laterales anteriores 

 nonnihil recurvati, dentibusque praediti validis. Regio branchialis ex- 

 pressior apparet, minus vero regio hepatica ; pedunculi oculorum crassi, 

 breves ; margo orhittE inferior a fronte disjuncta, orbitaque igitur a 

 fossula antennarum minime seclusa ; margo orbitae superior inferiori 

 prominentior. Articulus antennarum externarum basilaris liber mo- 

 bilisque ; articulus secundus canto oculi interno exceptus ad frontem 

 non prominet ; tigellus terminalis longior articulis tribus prioribus 

 plus duplo. Articulus caudalis tertius quartusque maris duobus pri- 

 oribus latiores. Par pedum tertium et quartum, quae paria prae ceteris 



longitudine eminent, inter se fere aequalia sunt. Species, G. tridens:
