COLLECTED IN 1863. O5 
Links between the village of Seaton Sluice and the mouth of 
Meggy’s Burn, and Mr. T. J. Foggitt has just shewn me speci- 
mens from the Ourham coast near Seaton Carew. It is new to 
the Tyne province, and Mr. Watson writes (Cybele Brit., vol. 2, 
p. 338), “* Very few of its localities hitherto recorded are situate 
upon the east coast of Britain, namely, those of Forfarshire and 
Norfolk, both of which may be deemed to require confirmation, 
although not so unlikely as to warrant their rejection.”’ Easily 
known from all the forms of P. aviculare by its large shining 
seeds, which are half as long again as the perianth. We also 
obtained characteristic examples of P. microspermum (Jordan), a 
variety of P. aviculare, on Hartley Links. 
Ruppia maritima, The true plant plentiful in the salt marsh 
at the mouth of Holywell Dene, and very fine at the mouth of 
Meggy’s Burn, near Blyth. | 
Juncus dijusus. Banks of the little stream not far from 
Bardon Mill Station, where the Hieracium, formerly called by 
Babington rigidum variety pictum, grows. 
Triticum acutum (D.C.) Plentiful at St. Mary’s Island, and 
growing also upon Hartley Links. Leaves with closely-placed 
rough hairy ribs, hardly at all enrolled, except quite at the 
apex, and the point not sharp. Axis of the spikelets smooth. 
IX.—On the Zcology of Zylton Dene.* By Georce S. Brapy. 
Tuere is, [ think, no inland spot in our district which possesses 
more interest for the student of the lower forms of animal life 
than Hylton Dene; and this not so much by reason of the 
abundance or excessive rarity of the species there found (though, 
indeed, in this latter respect it is somewhat remarkable), as on 
account of the curious association of what we are accustomed to 
regard, so to speak, as incompatible species, and the peculiar 
conditions under which they exist. 
Hylton Dene is a ravine or dell, through which flows a stream- 
let—in North country phrase a durn—tributary to the River 
* This paper was read also at the Newcastle meeting of the British Association.
