compact ; but compressible and resilient, and not very tough. 

 Pale yellow in spirit. 



Skeleton, a close-meshed fairly regular network of small stout 

 oxea ; with well-marked, parallel, multispicular primary lines, 

 three or four spicules thick, curving upwards and outwards and 

 separated by the length of a spicule ; secondary lines irregular, 

 uni- or multispicular, usually joining the primaries at right angles. 



Spicules, short, rather stout, slightly curved, rather bluntly 

 pointed oxea, measuring about 0'16 by 0*012 mm. (R.lSr. 594, 

 rather smaller in 1191). 



This species is distinguished from R. longiniainis chiefly Ijy the 

 size of the spicules. 



R.N. 288 (18 f; "wax yellow"); 594 (x, 19 f ; "cadmium 

 yellow"); 1191. 



Reniera fryetti, n. sp. 



Erect ; flabellate, but thick ; slightly proliferous. Margin 

 truncated, broad and flattened, covered with a finely porous 

 membrane, beneath which the numerous long, ascending, main 

 exhalant canals terminate. General surface subglabrous, minutely 

 punctate, rather uneven. Texture compressible, resilient, rather 

 soft and fi'iable. Colour in spirit warm dark brown. 



Skeleton, a close but irregular network of small oxea with 

 meshes .about one spicule's length wide ; sometimes distinct 

 multispicular primary lines may be distinguished. 



Spicules, rather slender, slightly curved, fairly gradually sharp- 

 pointed oxea, measuring about 0'12 by 0*005 mm. 



This species is a very remarkable one, easily distinguished by 

 the exhalant marginal pore-sieves and by the dark brown colour. 

 I have very great pleasure in dedicating it to my friend, Mr. A. 

 G. Fryett, as a slight recognition of his valuable aid in preparing 

 microscopical preparations of the Victorian sponges. 



R.N. 1141, 1183. 



Genus Halichondria, Fleming. 



Skeleton confused, may be fibrous, but never regularly i-eticu- 

 late. Spicules oxea or strongyla, usually long and slender. 

 Spongin scarcely appreciable.
