Dr. Keferstein describes the following new genus and spe-

large, solid leaf-shaped tentacles over the mouth, and no vascular system. — 
P. minutum y Kef, coast of Normandy.

Jourdain (/. 6*.) and Semper [L c.) give anatomical details of 
several species of Sipunculidea. See above, p. 712, 714. 
Aspidosiphon mulleri (Diesing). Schmidt (Mittheil. ntrw. Ver. Steier- 
mark. 1865, p. 56) recognizes in this species one described by himself in 1854 
as Lesinia farcimen. lie gives now a detailed account of its habits and ana-
