3816 Notices of New Books. 



which constitute, as it were, the pabulum on which the inquiring phi- 

 losopher of after years is to feed ; the others, for the registration of 

 facts of immediate as well as lasting interest, on which the science of 

 Natural History itself may be said to subsist. To take the ' Annals ' 

 confers that scientific status of which every aspirant for scientific re- 

 putation stands in need ; to read the others is equally necessary to 

 render him au courant with the scientific intelligence of the day. 

 Now that a new year has commenced, we purpose enriching our pa- 

 ges with a list of the contents of the previous month's ' Annals;' the 

 enormously increased circulation of the c Zoologist ' on the continent, 

 will render it the means of thus advertizing its friendly and highly 

 valued contemporary. 



The January number contains the following papers : — 



6 Descriptions of some newly discovered species of Araneidae.' By 

 John Blackwall, F.L.S. 



The new species are : — Thomisus versutus, Linyphia Meadii, L. 

 anthracina, L. pulla, L. alacris, L. ericaea, Neriene agrestis, N. vigi- 

 lax, Walckenaera exilis. Mr. Blackwall devotes about a page to the 

 description of each of these minims, a fact which in itself is a suffi- 

 cient proof of his elaborate painstaking. We have often had occasion 

 to regret the comparative isolation which has attended the labours of 

 this zealous naturalist ; and it is with feelings of no ordinary plea- 

 sure that we find he is now assisted by so competent a coadjutor as 

 our valued correspondent, Mr. Meade. 



6 Description of a new genus of Calanidae.' By John Lubbock, Esq. 



The genus is named Labidocera, from the somewhat forcipated an- 

 tennae : the species, L. Darwinii, was received from Mr. Darwin ; it 

 was taken in the Atlantic, off the coast of Patagonia, in latitude 38°.

 tius ; with Notes on some species of Cyclostoma from Borneo.' By

 testa, suffulta, and albidens.
