Friend: The Annelid Fauna of Worcestershire. 429 



worm was first described by Savigny as Enterion tetrcedvum, 

 on account of its square tail (whence also the name Allurus). 

 It was kept under notice thenceforth by all the authorities such 

 as Duges, Grube, Eisen, Oerley, Rosa, and others ; but, though 

 recorded by Johnston in 1865, was reported as new to Britain 

 in 1888. In that year it was found in Dorset, and as the 

 discoverer shortly afterwards became my neighbour and per- 

 sonal friend in Carlisle, his narration induced me to take up 

 the pursuit. Beddard of London, and Benham of Oxford were 

 just then giving the subject attention, and it may be said that 

 a new era in the study of British Annelids dates from that 

 period. Beddard has continued the work ever since, and in 

 1895 produced his magnum opus : a ' Monograph of the 

 Oligochaeta.' Rapid strides have been made since that year, 

 so that if the work were brought up to date, it would probably 

 contain twice as many species, while the margins would have to 

 be wide enough to receive as many more. 



Alluriis differs materially from Liimhrictis in externals. 

 The type is from one to two inches in length, usually a dirty 

 brown, but varying much in colour, with a square tail, the male 

 pores on the thirteenth segment, the girdle extending from the 

 twenty-second to the twenty-seventh, or thereabouts, and the 



tubercula from the twenty-third to the twenty-sixth,represented

Found at Malvern, Powick, and elsewhere. It is to be met 

 with wherever there is water, and is not only recorded for every 

 part of the British Isles where search has been instituted, but 

 also for almost every country in Europe, for Teneriffe, Val- 

 paraiso, and elsewhere. 



In my next contribution the different species of Allolobophora 

 at present known to occur in Worcestershire will receive atten- 

 tion. The white worms and water worms will be reserved for 

 a later paper. 



Memorials of Charles Darwin. London. 50 pp., 6d. 



It may quite possibly never again happen that so many interesting 

 memorials of Charles Darwin will be gathered together as were recently 

 at the British Museum (Natural History). The catalogue of these memo- 

 rials, issued at the small price of 6d., is therefore a most valuable record. 

 The guide book has been prepared by Dr. W. G. Ridewood, under the 

 superintendence of Dr. Sidney F. Harmer, who has written an interesting 

 Preface. Over two hundred and fifty exhibits are minuteh- described ; 

 the specimens being exhibited in twenty-four cases.
