M. F. Dujardin has published the description of a new marine animal, provided 

 with four pairs of jointed legs, which he regards as a new form of the Tardigrades, and 

 which he considers as more nearly allied to Acaridae than to Vermes, (Ann. Sci. Nat. 

 3rd ser. xv.) 



M. Dujardin has published (Ann. Sci. Nat. 3rd ser. xv. 158), a memoir on a small 

 marine animal (Echinoderus) from St. Malo, which he regards as a type between the 

 Crustacea and Vermes, the head being retractile, and armed with long flexible spines, 

 the body destitute of limbs, and terminated by small caudal plates and seta?. The in- 

 sect has much the appearance of a Dipterous larva. 



Report of the Library and Cabinet Committee for 1851. 



The arrangement of the British Lepidoptera has been completed : a quantity of 

 duplicates is the result, which we recommend may be offered in exchange among the 

 Members. 



The Curator has been, and still is, engaged in grouping, according to their affini- 

 ties, the various insects, for the most part exotic, that have from time to time been 

 presented to the Society, as a preliminary step towards their arrangement in the 

 cabinets. 



The faulty drawers in one of the cabinets, alluded to in last year's Report, could 

 not be secured against dust by chenille, as then proposed ; an arrangement has there- 

 fore been made to have the glasses put into tightly fitting frames, at a small expen- 

 diture. 



Mr. Lumley has furnished the books agreed upon, in exchange for those he re- 

 ceived from the Society ; and in accordance with the Resolution of this Committee, 

 the balance of £\ 18s. 6d. received from Mr. Lumley has been applied to the pur- 

 chase of the 7th vol. of Meigen's ' Diptera,' and the 2nd and 3rd vols, of Walckenaer's 

 ' Aptera,' to complete the sets of those works. The former has arrived, but the latter 

 are not yet come to hand. 



Thirty-two volumes of books in the Library have been bound at an expense of 

 £4 Is. 6d. ; and as many remain in want of binding, we recommend the Council to 

 allow £5 to be expended thereon this year. 



Mr. Wilkinson having kindly offered to take the principal part in forming a Cata- 

 logue of the Books under the two heads of " Authors" and " Titles," a suitable book 

 has been procured, and the work is commenced.
