Soulier agrees with Cosmovici, Meyer, and Brunotte (see also Ciiigi), 
as opposed to Claparede, that the perioesophageal glands of the Serpulaceae, 
which open to exterior by a common pore on dorsal side between branchial 
lobes, are nephridia, and have nothing to do with formation of tube. 
Latter is probably formed by secretion of the glands of the epidermis 
generally, and those of the collar and ventral shields (boucliers) particu- 
larly. Myxicola and rarely Branchiomma leave their tubes spontaneously 
and secrete new ones. The Serpulidcn , Spirographis , and Sabella are 
unable to form a new tube, and if they leave their old one it is to die.

Morphology. 
Jourdan (1). Malaquin (2). 
Meyer (1) concludes that the pair of long tentacles, which is character- 
istic of Tomopteris, and usually reckoned to the head, is really a pair of 
parapodia of the trunk, shifted forwards beyond the mouth. In young 
individuals these tentacles lie behind the mouth, and in course of growth 
advance forwards. They are not innervated from the brain, as hitherto 
supposed, but from the 2nd pair of ventral ganglia. Tomopteris there- 
fore no longer presents an instance of parapodia occurring on the prosto- 
mium.

Meyer (2) corrects Kleinenberg’s statement that the tostis and ovary 
of Lopadorhynchus arise at an advanced stage of development by invagina- 
tion from ectoderm. As a matter of fact they arise as proliferations
