Test elongate, subcylindrical, straight or more often slightly curved, 

 proloculum ovoid or somewhat fusiform, gradually passing into the 

 tubular chamber which is of smaller diameter than the proloculum; 

 wall smooth both without and within, composed of fine or occasional 

 coarse sand grains with an abundance of cement; yellowish or reddish 

 brown in color; aperture circular, at the open end of the tube. 



Fragmentary specimens occurred at Station 2070 showing the pro- 

 loculum and the base of the tube. Enough is present to show the char- 

 acteristic elongate proloculum and the very smoothly finished surface. 



Distribution. — Off Guadalupe Island, Mexico, in 350 fms. 



Hyperammina clavigera Heron-Allen and Earland 



Hyperammina clavigera Heron-Allen and Earland, Discovery Rep'ts,

 p. 74. 



This species was originally described from off the Falkland Islands. 

 Very elongate specimens nearly 10.00 mm in length occurred at several 

 stations. They are made up entirely of sponge spicules and apparently 

 closed at one end as in the type figures. It is difficult to distinguish be- 

 tween the broken portions of this species and those of Marsipella. There 

 is a possibility that Marsipella elongata may have been described from 

 the tubular portions of this species. Stations: 414, 299(?), 450, 451, 

 465(?). 



Distribution. — Gulf of California, San Jose de Cubo, 82 fms. ; Gala- 

 pagos Islands, north and south of Duncan Island, south of Albemarle 

 Island; Post Office Bay and Black Beach, Charles Island, in depths rang- 

 ing from 15 to 68 fms.
