GEODINELI-A ROBUSTA. 



1S°E., 1.7 km. (0.9 miles); drift N. 2° W.; depth 75-245 m. (42-134 f.); they 

 grew on a bottom of gravel and sponge spicules; the bottom temperature was 

 8.8° (47.8° F.). The specimen of var. megasterra was trawled at Station 2946 on 

 February 6, 1889, off southern California, in 33° 58' N., 119° 30' 45" W.; depth 

 274 m. (150 f.); it grew on a bottom of coaree gray sand; the bottom tempera- 

 ture was 13.6° (56.5° F.). 



T.VBLE SHOWING THE VARIETAL DIFFERENCES IN GEODINELLA ROBUSTA. 



In 1898 Thicle (Zoologica, 24, p. 12) described a geodid sponge with reduced 

 and irregularly arranged, partly axially situated teloclades and large ellipsoidal 

 sterrasters from the northwestern Pacific (Japan). As the specimen at his 

 disposal was merely a small fragment, he, although convinced that it did not 

 belong to any of the geodid genera then known, refrained from establishing a 

 new genus for it, and named it Geodia (?) cylindrica.
