Anatomy, Physiology, and Development. 
An important and suggestive essay on the development of the Poly- 
choita has been published by Kleinenberg (100); Viguier (120), and 
Albert (70), have written on the development of the Syllidce ; and 
Emery (88) on regeneration in various Polychccta. 
Jourdan (96-98) has made various contributions to our knowledge of 
the anatomy of some Worms, and Viallanes (117) has described the 
branchial skeleton of Sabella. 
The structure of Earthworms has been investigated by Beddard 
(71-76), who describes various new exotic forms, and, in (72) j gives an 
account of the variations exhibited by Perionyx excavatus.\ by Benham 
(78), who has also examined several new foreign species ; by Bergh (81) 
and Neuland (106), who treat of the structure and development of the 
generative organs;, and by Leydig (102), who has re-examined the colossal 
nerve-fibres. • Haematoporphyrin has been found by McMunn in the 
integument of L. terrestris ; J. Physiol, vii, p. 248. The mode of budd- 
ing in Oligochcuta has been studied by Bourne (82) in Nais ( Stylaria ) 
proboscidea . 
The organogeny of the Hirudinea has been investigated by Nusbaum 
(107) ; Whitman’s (123) essay on the Leeches of Japan is of great 
morphological value ; Bergh has studied (79) the ovum of Clepsine aud 
the Gnathobdellidce. Voigt (121) makes some additions to Dorner’s 
memoir on Branchiobdella varians ; see also Chworostansky (85), and 
Dutilleul (87). On the nervous system of Leeches, see Francis (90). 
Viguier (120) describes the following Phyllodoceidcc and A Iciopulce : — 
Pelagobia longocirrata, p. 377 ; 
Maupasia cceca , n. g. & sp., p. 382 ; 
Hydropliancs Jcrohnii, p. 385 ;
