Spongida. 

 Sponges are numerous on the Eed Clay, but they have not yet 

 been determined. 



FOEAMINIFEEA. 



Some of the Eed Clay dredgings are comparatively rich in cal- 

 careous bottom Foraminifera. Mr. Brady tells me that Stat. 276 

 (2,350 fathom), for example, has twenty-six species and varieties 

 of Lagena amongst other things; vphile Stat. 253 (3,125 fathoms) 

 has, in addition to six oceanic forms, thirty-one bottom species, 

 of which sixteen are calcareous and fifteen arenaceous. Arena- 

 ceous forms, however, usually constitute the larger portion of 

 the Foraminifera from extreme depths.
