At the following 11, stations specimens occurred which agree well 

 with the type of the species: D5172, vicinity of Jolo, 318 fathoms 

 (582 meters), bottom temperature not recorded; D5424, Jolo Sea, 

 340 fathoms (622 meters), bottom temperature 50.4° F. (10.1° C); 

 D5425, Jolo Sea, 495 fathoms (906 meters), bottom temperature 

 49.4° F. (9.7° C); D5526, between Siquijor and Bohol Islands, 805 

 fathoms (1,472 meters), bottom temperature 52.3° F. (10.1° C); 

 D5569, north of Tawi Tawi, 303 fathoms (554 meters), bottom 

 temperature, 52.3° F. (10.1° C); D5570, north of Tawi Tawi, 330 

 fathoms (604 meters), bottom temperature 52.3° F. (10.1° C); 

 D557i, north of Tawi Tawi, 340 fathoms (622 meters), bottom tem- 

 perature 52.3° F. (10.1° C.) ; D5575, north of Tawi Tawi, 315 fathoms, 

 (580 meters), bottom temperature 52.3° F. (10.1° C); D5582, Darvel 

 Bay, Borneo, 890 fathoms (1,628 meters), bottom temperature 

 38.3° F. (3.5° C); D5584, Sibuko Bay, Borneo, 292 fathoms (535 

 meters), bottom temperature 44.3° F. (6.8° C); and D5639, Mo- 

 lucca Sea, 1,560 fathoms (2,853 meters), bottom temperature not 

 recorded. 



The material from the Philippines serves to more clearly fix this 

 as a very definite species. The short, broad form, arenaceous walls 

 with smooth surface, well finished, are very apparent. The color is 

 usually gray or brownish, but at D5172 very typically shaped speci- 

 mens were found with tests of calcareous sand and white in color.
