Leuckart has continued (27) the new edition of his “ Die Parasiten 
des Menschen ” ; the first part of the work has been translated into 
English by Hoyle (28).

Korotneft’s account (24) of Ctenoplana Jcowalevslcii, n. g. & sp., shows 
that, like Cceloplana , it is intermediate between the Ctenophora and the 
Planaria. 
Dinophilus is shown by Weldon (42) to have, in addition to its Turbel- 
larian characters, relations to the Archiannelids. 
For observations on Syndesmis, which appears to be intermediate be- 
tween the Turbellaria and the Trematoda, see FKAN901S ( 9 ). 
The histology of acoelous Planarians has been investigated by Delage 
(7), and the structure of rhabdoccelous forms by Bohmig (4). Hallez 
(15) has found what appears to be an olfactory organ in Mesostoma 
lingua ; the anatomy of M. personatum is the subject of a preliminary 
notice by Jaworowski (22).

(45)], and on that of Bip>alium ; Bell, J. R. Micr. Soc. (2) vi, pp. 1107

The most striking point in Hubrecht’s account of the Embryology of 
the Nemertinea (17), is the demonstration of the mesoblastic origin of 
the nervous system. 
The structure and metamorphosis of Pilidium has been investigated by 
Salensky (38), who derives the Nemertine proboscis from that of the 
Turbellaria.
