Looks like Zygiella x-notata. They are egg sacs, can't see them too well and may be last years, looking at the colour though.

Dear thes3raph1m,
Xygiella seems to be active all year round (unless Araneus) also, it is a typical "window corner" spider, and your photo seems to have been taken on a window frame. You can see freshly made webs throughout the winter and these look similar to Araneus ebs, both being orb spiders, but for a section of the web that lacks transversal threads in Xigiella. If you look closer, the thread that connects the center of the web to the spider legs, and allow the spider to 'feel' the web goes over that section. The spider hides almost in the same plane as the web, and that's why windows and other 'flat' frames are used by this spider. |

Hi Action-Man, you must be looking at the 1945 second edition of 'The Spiders and Allied Orders of the British Isles' by Theodore H. Savory then, when it was Zygiella litterata.
If you had referred to the first edition of 1935 it would have the name Zilla litterata, and at the time of 'British Spiders' by E. F. Staveley in 1866 she had it as Epeira callophylla.
It demonstrates how species are recategorised every so often.
I'd recommend the Collins Field Guide - Spiders of Britain and Northern Europe by Michael J. Roberts for more reliable identification, though you often can't beat the old books. I quite often use Locket and Millidge as well as the Roberts Bible.

Yes i understand they must be re-classified through time for one reason and another.
And yes thats the book in question, i wont add any appendum`s to it, that would be sacrilege, just improve my memory.
Does the Collins Field Guide include all the known British species ?, and does it use common names and Latin ? ... | | | |
