116 THE ZOOLOGIST. 



water, this interesting worm occurs, at Herm, under stones in pools 

 between tide-marks. The synonymy of the groups dealt with is 

 most completely and conveniently given, the references being given 

 strictly in chronological order, a plan which, though it uses up a good 

 deal of space owing to the consequent repetition of names, more 

 especially as each reference has a line to itself, is thereby of great 

 assistance to the ready finding of a particular reference. It is worth 

 noting that the common Arenicola marina was described as Lumbricus 

 marinus by Belon as long ago as 1553 ; and the references to it between 

 that date and the present day fill up no less than five pages of this 

 publication in quarto — a most unwieldy size, by the way. 



Part II. contains the plates illustrating Part I., the only illustrations 

 in which volume are line drawings in the text illustrating anatomical 

 and other details. These plates, numbered Ixxxviii to cxi, depict 

 both the whole animals and various details of structure, such as 

 bristles, etc., and are most beautifully executed, reflecting the greatest 

 credit on the artists, Miss A. H. Walker and the late Mrs. Albert 

 Giinther. Six of them — Ixxxviii. to xciii — should have been in colour, 

 but owing to the war it has proved impossible to get these through, 

 and so all have, very rightly in our opinion, been issued in black and 

 white, to render the text at once available to workers. If ultimately 

 obtainable, the coloured plates are to be sent to subscribers for 1916. 

 We might suggest that these would find it interesting and useful to 

 colour these black and white plates themselves, as opportunities 

 occur of getting living specimens. We have here a small criticism 

 to make — the degree of magnification is generally given in the detail 

 figures, but those of the whole animal are generally spoken of merely 

 as " enlarged " ; a more precise indication of the degree of enlarge- 

 ment would, we think, have been of service to collectors unused to 

 this group. We should like especially to draw attention to the figures 

 of the extraordinary pinnate bristles of Poecilochatus serpens given 

 on the last plate ; these are so extremely like feathers of the simple 

 type consisting only of shaft and barbs, such as some of the Emu's, 

 that no one could, on seeing these drawings alone, think they could 

 have been meant for anything else.
