tion between the ciliated infundibula and the interior of the anal tubes. 
Lampert (Z. wiss. Zool. xxxix. pp. 334-342) describes as new Thalassema 
formulosum, caudex, sorbillans , and vegrande\ the species of the genus 
are divided into two groups, in accordance with the separation or not of 
the lougitudinal muscles into bundles. The number of the segmental 
organs is not of much use to the systematise

Italian). 
The monograph of Grassi (51) contains an account of the two genera, 
Spadella and Sagitla , and the twenty supposed species; the Clicetognatha 
are regarded as a very distinct group, particularly interesting at this 
moment on account of the characters of their peripheral nerve-plexuses. 
Gourret’s new species (49, 50) appear to be very abundaut at Mar- 
seilles ; the lateral fins are always without rays.
