Notice in regard to the Actinia maculata. By the Editor. 



An actinea much resembling the species (if indeed not the 

 same), of which our young friend Dr Coldstream has given a 

 description and figure at page 236. of this volume, I find figured 

 and described by Bohadsch, in his Anim. Marin, p. 135, &c., 

 under the name Medusa palliata. That author says, the sur- 

 face of the skin is white, and spotted with most elegant purple 

 dots. Tn the month of August it is often taken in the fisher- 

 men's nets. It appears to move about in the sea, and also very 

 frequently it occurs investing shells. Its mode of investing 

 shells is given by Bohadsch in detail. The same species, ap- 

 parently, is described by Otto, in t. ii. of the Nova Acta Phy- 

 sico-Medica Acad. Cjes. Leopoldina-Carolinae Naturae Curio- 

 sorum, p. 288, 9, 90, 1, 2; and in Plate 40. there are six 

 coloured figures of it, under the name Actinia carciniopoda. 

 He describes it as white, with many delicate pale bluish-grey 

 stripes running from the centre to the circumference, and marked 

 with numerous large roundish spots, of the most beautiful pur- 

 plish colour. The habits and manners of the animal are men- 

 tioned, but our limited space will not allow us to state them here. 



Notice respecting the Nervous System of ike Crustacea *. By 

 MM. V. AuDouiN and Milne Edwaeds. 



Among the most curious and most important researches to 

 which anatomists could devote themselves, are without contra- 

 diction to be reckoned those which tend to make known to us 

 the course which nature has followed in the formation of each 

 being, and in the creation of the different series which seem to 

 be constituted by animals. This result may be attained in two 

 different ways; — by the comparison of the modifications which 

 the same organs present in a great number of different animals, 

 and by the study of their mode of development, or of the kinds 

 of metamorphoses which they undergo in the same individual at
