Skeleton:
No information given.
Distribution: Southern California.
Depth: Subtidal.
Note: Similar to Leucosolenia eleanor but Oxeas much shorter than those of L. eleanor. Was originally described by Sim & Bakus as L. tenuis Dendy & Row, 1913. Originally described from Europe (Schuffner, 1877) ,then Japan (Dendy & Row, 1913, and Tanita,1942). Sim & Bakus note that it also occurs in British Columbia but that is not substantiated by current records.
