but uneven, with minutely reticulate dei'iual membrane. The 

 texture is soft, compressible, resilient and loose. Tlie colour in 

 spirit is almost white, in life, usually orange. 



The skeleton is loosely fibrous, forming a very irregular net- 

 work, the primary fibres being stouter and better defined than 

 the secondaries. There appears to be little, if any, spongin. At 

 the surface the primary fibres break up into radiating tufts of 

 oxea which support the dermal membrane and give rise to the 

 characteristic dermal reticulation. Numerous spicules are 

 scattered between the ill-defined fibres. 



Megasderes, slightly curved oxea, i-ather long and slender and 

 gradually sharp-pointed at each end, measuring about 0'29 by 

 0-0042 mm. 



Microscleres, numerous slender, hair-like rhaphides, about 0-18 

 }nm. long ; usually scattered separately but occasionally associated 

 in loose whisps or bundles (trichodragmata). 



Mi\ Carter seems to have rather over-stated the size of the 

 oxea and he has omitted to mention the rhaphides, which are 

 plentiful in his specimens in the British Museum. 



The species is very common, there Ijeing no less than twenty- 

 four distinct specimens in the collection entrusted to me. The 

 life-colours of thirteen of these are recorded. Orange is the 

 prevailing tint and there are no great deviations from this. 

 The stations from which the species is recorded are 1, 5, G, 14, 

 X A, X B, X C.

Genus TeJaiiia, Gray. 



Megascleres of two kinds: (1) Monactinal ; smooth styli, 

 forming the main skeleton ; (2) Diactinal ; tylota, strongyla or 

 tornota, typically dermal. Microscleres always present in the 

 form of hair-like rhaphides.
