The current part of the Transactions of the Hertfordshire Natural History 
Society contains a large number of noteworthy papers. As may be imagined, the 
fauna of the county comes in for a large share of attention, and there are notes on 
lepidoptera, beetles, land and fresh-water molluscs, birds, and albino moles.
