L'auteur confirme ce que Dubreuil et Moquin-Tandon avaient observé. U Ancy- 

 lus est hermaphrodite. Pendant l'accouplement les animaux jouent tantôt le rôle 

 de mâle tantôt celui de femelle. Il n'y a pas double copulation. Les pontes sont 

 fréquentes, les oeufs pondus ne sont pas nombreux.

De chaque côté de la masse viscérale et en avant , disposé entre le connectif 

 cérébro-viscéral et le nerf branchial, existe un ganglion reniforme, qu'un pédicule 

 relie avec elle. Les branches nerveuses, qui partent de ce ganglion, forment un 

 réseau à larges mailles, qui se distribue dans les organes de la vie végétative.

Contributions from the Zool. Laboratory of the Museum of Compar. Zool. un- 

 der the dir. of E. L. Mark, XXXIX. — »Quartets« are called the four related cells 

 of one generation, »quadrants« are the regions occupied by the four blastomeres 

 (a. being the left anterior, b. the right anterior, c. the right posterior, d. the left 

 posterior). The term »spiral« is used to indicate the divergence immediately after 

 cleavage of the centre of the nucleus of the upper one of two daughter cells from 

 the vertical plane passing through the corresponding portion of the lower cell 

 and the vertical axis of the egg (in the former use of the term, by Lang, Hey- 

 mons etc., in some cases the lower cell, in other cases the upper cell of a pair of 

 daughter cells was regarded as the fixed one). This divergence is determined by 

 the position of the spindle. In Limax (as in Nereis, Umbrella, Crepidula) there 

 exists an alternation in the direction of the spirals in successive generations. The 

 rate of cleavage is dependent not only on the amount of yolk , but also on the 

 quality of the protoplasm and of the yolk.
