water. Surely more than one species of Gordiida3 ought to 

 occur with us.^ 



AcANTHOCEPHALA. — With the exception of Echinorhynchus 

 gigas, Goeze, of which Dr Ash worth has shown me a specimen 

 from the intestine of a pig, I have no records under this sub- 

 order. But no doubt a number of other species, such as 

 K proteus in fresh-water fishes, K acus in whiting, etc., are 

 to be found in the district. [I have since got E. acus, Rud., 

 in bullheads {Cottus scorpiits) from North Berwick, Oct. 1908 ; 

 identified by Dr Nicoll, who has recently published in Ann. 

 and Mag. Nat. Hist., two papers on the Entozoa of marine 

 fishes and shore-birds at St Andrews.] 



CH^TOGNATHA. 



The only representative of this small class of pelagic 

 animals that has been recorded from the Firth of Forth 

 is Sagitta hipunctata, Q. and G. It was obtained by the 

 German Expedition of 1872 off St Abb's Head, and has since 

 been found commonly by the naturalists to the Fishery 

 Board — Dr Scott and Mr Pearcey — within the Forth, at 

 various stations as far up as the neighbourhood of Inch- 

 keith.2 It occasionally occurred in the tow-net, Dr Scott 

 tells me, in such numbers as to be a positive nuisance. 

 Perhaps further investigation will show that more than one 

 species of Chsetognath occurs in our waters. A useful table 

 of known species is given in vol. ii. of the Cambridge Natural 

 History. 



ROTIFERA. 



Although in a general way Eotifers are favourite objects 

 of study with the microscopist, comparatively little has been 

 done in determining and recording the species to be found in 

 this district. As a class they abound almost everywhere 

 from the sea-shore to the hill-tops, a handful of damp moss, 

 water-weed, or algae, seldom failing under proper treatment 

 to yield numerous individuals and not a few species. 



^ I have since obtained a second species not yet identified.
