Over the years with an interest in the more formal study of myriapods, especially centipedes, I have also accumulated a few items of what we might call \"trivia\" - prints, pictures etc. The two items here come into that category and I know there are many more like them around and they are offered as light relief for Bulletin readers. I know little about The Penny Magazine but it clearly represents a cheap, presumably weekly, publication dedicated to that great Victorian aim of \"self improvement\". This issue comprises eight pages with items as varied as \"Essays on the lives of Remarkable Painters No.XXXI: Andrea del Sarto\", \"The English and Irish Ordnance Surveys\" and \"The Hareem of Ibrahim Pasha\". I have abridged the item on Centipedes and Millipedes from the original three pages. \"The Rabbit and the Centipede\" comes from a children\&$\#$39;s book of 1907. I am not sure that it sheds any particular new light on myriapod locomotory mechanisms.

The P450 family (CYP genes) of arthropods encodes diverse enzymes involved in the metabolism of foreign compounds and in essential endocrine or ecophysiological functions. The P450 sequences (CYPome) from 40 arthropod species were manually curated, including 31 complete CYPomes, and a maximum likelihood phylogeny of nearly 3000 sequences is presented. Arthropod CYPomes are assembled from members of six CYP clans of variable size, the CYP2, CYP3, CYP4 and mitochondrial clans, as well as the CYP20 and CYP16 clans that are not found in Neoptera. CYPome sizes vary from two dozen genes in some parasitic species to over 200 in species as diverse as collembolans or ticks. CYPomes are comprised of few CYP families with many genes and many CYP families with few genes, and this distribution is the result of dynamic birth and death processes. Lineage-specific expansions or blooms are found throughout the phylogeny and often result in genomic clusters that appear to form a reservoir of catalytic diversity maintained as heritable units. Among the many P450s with physiological functions, six CYP families are involved in ecdysteroid metabolism. However, five so-called Halloween genes are not universally represented and do not constitute the unique pathway of ecdysteroid biosynthesis. The diversity of arthropod CYPomes has only partially been uncovered to date and many P450s with physiological functions regulating the synthesis and degradation of endogenous signal molecules (including ecdysteroids) and semiochemicals (including pheromones and defense chemicals) remain to be discovered. Sequence diversity of arthropod P450s is extreme, and P450 sequences lacking the universally conserved Cys ligand to the heme have evolved several times. A better understanding of P450 evolution is needed to discern the relative contributions of stochastic processes and adaptive processes in shaping the size and diversity of CYPomes.
