Geological speak with regret of the resignation of their recently-appoint- 

 ed Curator, Mr. Searles Wood, whose health would not permit him to 

 continue in office. Referring to the Society's collection of crag fossils, 

 the Museum-Committee state that Mr. Wood "has added to it most li- 

 " berally from his private cabinet, and has by this means augmented the 

 "species of Mollusca and corals from about 100, of which they before 

 " consisted, to no less than 400, besides inserting many specimens in a 

 " more perfect state, of species of which the Society already possessed 

 " some individuals. Duplicates, moreover, of many species common to 

 " the upper and lower crag, have been introduced for the sake of compa- 

 " rison ; and the localities of all Mr. Wood's specimens, verified from his 

 " own observations, have been carefully noted on the tablets. By these 

 " important donations the number of drawers containing organic remains 

 " of the crag, has been increased from 10 to 27." 



The Zoological Society have recently been so unfortunate as to lose 

 the chimpanzee and the male and female orangs, all of which were, a 

 short time since, alive, and exhibited together in the Regent's Park. — 

 The great object of interest now at the Gardens is the young giraffe, the 

 birth of which took place about ten days since. No similar instance has 

 ever previously occurred in Europe.

Art. I. — 1. Monographia Chalciditum. By Francis Walker. London: 

 Bailliere. 1839. 8vo. pp. 330. 



2. Hymenoptera Britannica : Alysia. Auctore A. H. Haliday. Fascicu-

The cessation of the publication of the ' Entomological Ma- 

 gazine,' previous to the completion of the Monographs upon 

 the Chalcididce by Mr. Walker, and the Ichneumones adsciti 

 by Mr. Haliday, has compelled these gentlemen to resort to 

 separate publication for the termination of their memoirs. — 

 Mr. Walker's work, therefore, instead of being a ' Monogra- 

 pliia Chalciditum] is a monograph only of four of the genera 

 of that family, with supplemental species of some of the other 

 genera described either in the ' Entomological Magazine,' or 

 the ' Annals of Natural History.' The present volume con- 

 tains descriptions of 452 species, chiefly inhabitants of this 

 country, and now for the first time described. It must there- 

 fore be considered an important addition to our Fauna. 



Mr. Flaliday's brochure comprises descriptions of about for- 

 ty British species "belonging to the Ichneumonideous genus 

 Alysia and its subgenera, — sixty -one species of the same ge- 

 nus having been previously described in the * Entomological 

 Magazine.' It also comprises a very valuable Synopsis of
