This species differs from the preceding in the characters of the wall, 

 being made almost entirely of sponge spicules. This seems to be a defi- 

 nitely selective character as both species were found occasionally at the 

 same station without any real intermediate stages. It has a wide distri- 

 bution according to the published records. In our material it has oc- 

 curred at the following stations: 1047, 1046, 226, 283, 299, 441, 461, 

 227, 80, 2070, 2005, 2051, 2063, 2064, 2010, 2065, 1037. 



Distribution. — In Monterey Bay in 85 fms. ; in Tagus Cove, Albe- 

 marle Island, Galapagos, in 80 fms.; in the Gulf of California, off San 

 Pedro Nolasco Island, in 60 fms.; off Catalina, at Long Point in 120 

 fms.
