Half a century ago, Belgian Zoologist Bernard Heuvelmans first codified cryptozoology in his book On the Track of Unknown Animals.

The Centre for Fortean Zoology (CFZ) are still on the track, and have been since 1992. But as if chasing unknown animals wasn't enough, we are involved in education, conservation, and good old-fashioned natural history! We already have three journals, the largest cryptozoological publishing house in the world, CFZtv, and the largest cryptozoological conference in the English-speaking world, but in January 2009 someone suggested that we started a daily online magazine! The CFZ bloggo is a collaborative effort by a coalition of members, friends, and supporters of the CFZ, and covers all the subjects with which we deal, with a smattering of music, high strangeness and surreal humour to make up the mix.

It is edited by CFZ Director Jon Downes, and subbed by the lovely Lizzy Bitakara'mire (formerly Clancy), scourge of improper syntax. The daily newsblog is edited by Corinna Downes, head administratrix of the CFZ, and the indexing is done by Lee Canty and Kathy Imbriani. There is regular news from the CFZ Mystery Cat study group, and regular fortean bird news from 'The Watcher of the Skies'. Regular bloggers include Dr Karl Shuker, Dale Drinnon, Richard Muirhead and Richard Freeman.The CFZ bloggo is updated daily, and there's nothing quite like it anywhere else. Come and join us...

Some interesting snippets from the 1930 Volume of The Transactions of the Devonshire Association

My appeal for volunteers during the keynote speech at last year's Weird Weekend was answered by enthusiastic young couple Tim and Graidi Taylor-Rose. Every other Sunday they wind their way to Woolsery and do CFZ stuff that has been long overdue. This includes going through nearly a century's worth of the Transactions of the Devonshire Association, which are on loan to the CFZ from our old pal Lionel Beer

I have always been interested in freshwater jellyfish and the matter has come up on several occasions on these pages but I never knew that the first UK records of them in the wild were in Exeter....

Scientific Memoranda report 1930

In June, 1880, the late Sir Ray Lankester made known, through the pages of Nature, the discovery of a freshwater medusa that had appeared in the Victoria regia tank at the Botanical Society’s Gardens in Regent’s Park, and which he named Limnocodium sowerbii. It was supposed to have been conveyed from one of the great African lakes in the hydrosome (or polyp) stage on the rootlets of some plant.

Some years there were plenty of the medusae in the tank, other years scarcely any. Then it disappeared altogether. Later on furthe
r specimens were found in a tank at the
Sheffield Botanical Gardens. The medusae appeared and disappeared sporadically in tanks in Botanical Gardens in which the water was of about 70° F. The hydrosome stage was eventually found and described (Pro. Roy. S0c.,XXXVIlI,9). So far Limnocodium has been found in England only in artificial situations, but in Nature of January 4th, IQBO, Mr. Rupert Vallentin of Exeter, writes describing the occurence of the medusae in great quantities in the Exeter Ship Canal in the summer months of 1929. As the surface temperature of the water gradually lowered with the approach of autumn the medusae gradually disappeared, and after the middle of October none were to be found. The hydroid stage, which must exist in the canal, has not yet been found. Although both hydroids and medusae have been found in natural conditions (ponds, etc.) in N. America, this discovery of them in the Exeter Ship Canal seems to be the first time they have been observed in such conditions in Europe.

Later systematists have renamed the medusa Craspedacusta sowerbii against which protests have been made. Quite recently another species of freshwater medusa (Microhydra ryderi) has been found in a private freshwater aquarium at Bournemouth. The minute fixed hydroid stage of this was found in the aquarium also. G. T. HARRIS.

Cordylophora lacustris Allman

This interesting zoophyte was also discovered recently by Mr. Vallentin in the Exeter Ship Canal. It was originally discovered almost simultaneously in England and Belgium about 1854, and its great interest lies in the fact that it is a marine animal that has gradually adapted itself to a fresh-water environment within recent times. Carl Semper relates (Animal Life) that in his student days it was only known as a marine or brackish water species. Then it gradually ascended estuaries and adapted itself to fresh-water conditions. Even in Semper’s days it had appeared in the great water pipes of the city of Hamburg “ in such enormous quantities as to impede the flow of water through the pipes."

In England it was first found in the West India and Commercial Docks, and by about 1868 it had found its way, presumably by means of canal barges, into the Midlands, where it was established in the canals of Staffordshire. About 1890, or a little later, it was reported from the rivers and broads of Norfolk. I myself collected it from the river at Potter Heigham, about 1899, where it was growing profusely. It would be interesting to observe how far it proceeds up the Exe, the probability being that when it meets the strong current above Exeter, its further progress will be stayed. G. T. HARRIS.
