near Winchburgh, and a pool on Largo Links. Scott and 

 Lindsay have recorded it from the Upper Elf Loch, Braid 

 Hills, in their paper mentioned under Protozoa and Kotifera. 

 Besides this species, I have seen other two forms. One, from 

 pool on Largo Links in August last, agreed well with 

 Ghcetonotus maximus, Ehr., as described and figured in 

 Zelinka's account of the group.^ 



Nineteen Gastrotricha are recorded from Europe, seven of 

 which have, it appears, been detected in Britain, and no 

 doubt there are others awaiting discovery. I should expect 

 five or six at least to occur here. 



CH^TOPODA. 



(POLYCH^TA AND OLIGOCHiETA.) 



Our knowledge of the Annelids of Forth is far from 

 satisfactory. Even the deeply iDteresting and often truly 

 beautiful marine forms, the Polychsetes, have never been 

 adequately catalogued, while printed records of Oligochsetes 

 are all but non-existent. Professor M'Intosh's splendid 

 Monograph of the British species, now partly published, 

 will, let us hope, stimulate local interest in them. 



PoLYCH^TA. — Despite its title, very few records per- 

 taining to this group are to be found in Professor Jameson's 

 " Vermes " of the Forth, etc.^ Sir J. Dalyell made valuable 

 observations on Scottish marine " Bristle- worms," but owing 

 to the want of precise localities, and the difficulty in identify- 

 ing many of his species, few records definite enough for our 

 purpose can be culled from his writings either. Firth of Forth 

 specimens of about a dozen species, mostly collected by 

 Lieutenant Thomas, RIST., are noted in Johnston's British 

 Museum Catalogue of Non-parasitic Worms, 1865; and a 

 like number are recorded by Mobius in his report on the 

 " Vermes " obtained by the German North Sea Expedition. 

 Leslie and Herdman, confining themselves entirely to the 

 records of Johnston and Mobius and their own observations, 

 give a short list of 27Polych8etes in their "Invertebrate Fauna." 

 Henderson's "Additions" {I.e.) make known two others, namely ,

 of Forth and other parts of Scotland" {Mem. Wern. Soc, i. p. 556, 1809).
