Miscelianeous. 71 



During the past two years I have pretty thoroughly investigated 

 the Algology of the coasts of Durliam and Northumberland, with the 

 result of adding several very interesting species to the local flora. 

 This coast is in many respects unfavourable to the growth of Algse, 

 being remarkably destitute of those quiet inlets in which the more 

 delicate species luxuriate, and, in common with the whole of our 

 north-eastern shore, being washed by cold northern currents. There 

 are, however, in many places, large tracts of rock left bare at ebb 

 tide, which form good searching grounds for those plants which 

 can bear exposed situation and cold climate ; but where strictly 

 southern species occur, they are invariably ill-grown and stunted. 

 Several such will be found in the annexed hst. It includes those 

 species only which have been hitherto unknown, or imperfectly 

 known, as natives of the north-east coast, and which thus possess 

 some interest as regards their distribution. 



Myrionema punctiforme, on Polysiphonia areolata, at Seaham 

 Harbour, Durham, April 1859. 



Sphacelaria filicina, near Seaham Harbour, Durham, 1859 and 

 1860. In a very small pool. Probably now extinct, owing to the 

 close proximity of rubbish from some new blast furnaces, 



Sphacelaria fusca, near Seaham Harbour, Durham, 1860. 



Ectocarpus fenestratus, Whitley Rocks, Northumberland, 1860. 



sphcBrophorus, not uncommon. 



Rytiphlcea thujoides, St. Mary's Island, Northumberland, 1860. 



Polysiphonia parasitica and P. byssoides, very fine near Whitley, 

 Northumberland, and on other parts of the coast. 



Dasya Arbuscula, Cullercoats, Northumberland, Mr. R. Foster. 



Gymnogongrus norvegicus, near Sunderland, Durham. 



Phyllophora Brodicei, not rare. 



Cruoria adhcBrens, Tynemouth, &c., Northumberland. 



Ceramium botryocarpum, near Seaham Harbour, Durham. 



flabelligerum, St. Mary's Island, Northumberland. 



Callithamnion Arbuscula, frequent on the Northumberland coast. 



floridulum and C. sparsum, Roker, Durham. 



Cladophora gracilis, Hartley, Northumberland.

Halmaturus stigmaticus. 



Face, sides of the body, outer side of the fore limbs, and the flanks 

 rufous, more or less interspersed with whitish-tipped hairs ; outer 

 side of the hinder limbs rich rusty-red ; occiput dark brown, inter- 

 spersed with silvery-tipped hairs ; ears externally clothed with long 

 black hairs, and narrowly fringed on the front edge with white ; 

 upper surface of the body blackish-brown, interspersed with nume- 

 rous whitish-tipped hairs, and gradually blending with the rufous 

 hue of the flanks ; down the back of the neck an indistinct line of a 

 darker or blackish hue ; across each haunch a broad and conspicuous
