General Morphology. 
Hatschek (85) has examined the trochophore of Eupomcitus uncinatus , 
and has discovered an auditory vesicle ; the same is found in an allied 
larva from Faroe. Fewkes (79) gives an account of the larva of Spirorbis 
borealis ; the shell is at first horn-shaped. Hatschek (84) finds that 
PolygorcUus confirms his account of the development of the nervous 
system, as against Kleinenberg. Drasche (76) has studied Pomatoceros 
and Sabellaiha, and (77) Spinther and Owenia, and Roule (103) Dasy- 
chone. 
Harker, Nature, xxxii. p. 564, thinks that the colouration of the anterior 
segments of the Maldanidce is not of a respiratory function. 
Pruvot (99) gives an elaborate account of the nervous system of the 
Polychceta , which is always to some extent continuous with the hypodermis. 
The musculature of Chaetopods has been investigated by Rohde (101), and 
the vascular system by Jaquet (88). KiikenthaPs (90) observations were 
made on a species of Tubifex. Beddard (68, 70, 72) has made further 
contributions to our knowledge of the nephridia. 
Ude (110) describes the structure and arrangement of the dorsal pores 
of terricolous Oligochccta.
