The species has long been known from St. Jago, one of the 

 Cape Verde Islands (O. Schm.), from the coasts of Spain and 

 Portugal (S. Kent,) from the Strait of Gibraltar (924 m.; Tops.) 

 and from oft* Little Ki Island (236 m.; " Chall."). It occurs also 

 in the Sas-ami Sea, so that it seems to be a verv widely dis- 

 tributed species. 



In the Sagami Sea, in all nearly a score or more specimens 

 have thus far been obtained at Döketsba, Mochiyama, Inside and 

 Outside Okinose and at a. spot off' the east coast of Vries Island. 

 The depths from which they were obtained were 183-572 m. 

 (100—313 fms.). The species is known to occur there along with 

 Eaplectella inarshalli, Leucopsacxs oHhodocus, L. scoliodocus, Slauro- 

 calyptus pleorhaphides, Grotcroinorplia mojeri, Hyalonema affine, 

 Semperella domata, Farrea. sp., Ilexacluiella lorica, etc. 



Tlie species is always lirmly attached at base tu the sub- 

 stratum. I have seen it growing on pebbles and shells as well 

 as on dead remains uf a coral, of a Bryozoa, of a Lithistid, of a 

 Farrea and very fieipiently on Hexact'inella loriea. 



In the Challenger Eeport (p. 131), F. E. Schulze mentioned 

 tliat the sponge might sometimes be rooted in a soft bottom 

 by means of long anchors ; this mention, so far as it goes, was 

 probably founded upon observations, not on the present species, 

 but on young Lophoealyx ph'dippinemis, specimens of wliich, as 

 we are told by him, were contained in the same bottle together
