460 THE ZOOLOGIST. 



(A. chlorotica) ; while some were of a brilliant green, others 

 were yellow or golden. The remaining Lumbricida offer few 

 subjects for special remark, except that certain species of the 

 Dendrobcena group seem to be abundant. 



It is among the Enchytrgeids that the most important 

 discoveries have been made. The new species will be mentioned 

 later. Meanwhile, a few remarks respecting those already known 

 as British may not be out of place. Mr. Hillman took some 

 specimens from " a rotted elm, a piece of which is enclosed on 

 the chance that the worms peculiar to this may remain in it." 

 This accounts for my finding no fewer than eight specimens of 

 F. ulmicola, while only three of F. michcelseni were present. 

 The specimens were adult, and have enabled me to confirm and 

 extend my original diagnosis. Fridericia perrieri was plentiful, 

 but one specimen seemed to be clearly referable to F. agricola. 

 While there were seven specimens of F. polychata all closely 

 resembling the type, there was one specimen which differed so 

 widely from the rest that I have for the present given it place as 

 a distinct variety. Similarly, there were two specimens of F. 

 leydigi, and three others closely allied thereto, which have 

 puzzled me greatly. About a dozen species are typical British 

 and European, but some of the rest are critical, and one must 

 hope for a further opportunity of examining new material in 

 order to solve the problems which they present. 



New Records. — The family of Enchytraeids is the only one 

 which has supplied material new to Britain or to science. Here 

 one new Mesenckytrceus, two new Henleas, and certain new or 

 little known Fridericias claim attention. As already stated, 

 Henlea was represented by four species. Eleven specimens of 

 H. rluetica, our best known species, perhaps, were collected with 

 four II. hibernica. The others have not been found in Britain 

 before. 



1. Henlea insula, sp. nov. 



Description . — Length, when alive, 12-14 mm. Segments 50-65. 

 Setae usually 8 in front, gradually diminishing from 6 to 4 

 behind. No oesophageal glands, therefore falling into the author's 

 Hcnleanella division ; no bulb, but oesophagus going gradually 

 into the intestine as in Fridericia and Enchytraus. Dorsal vessel 

 arising behind the clitellum in 17/18 or 19/20 segments.
