metabolism, of males, to resemble those of females. This paper records the re- 

 sult of observations by micro-chemical and quantitative chemical methods on the 

 quantity of fat and Glycogen in the livers of infected crabs. The methods used 

 are fully described. It is shown that the roots of Sacculina take up fatty mate- 

 rial, and lay it down as neutral fat as do the developing eggs of a normal fe- 

 male. In a crab about to moult, a quantity of glycogen is deposited under the 

 skin, associated by a pink lipochrome -w hich gives rise to the skin pigmentation. 

 This lipochrome is not accompanied by much fat, as is the yellow pigment in 

 the blood of females with maturing eggs. Sacculina inhibits the infected crab 

 from moulting, and this is accounted for by the absence of glycogen, which is 

 not due to general bad nutrition, but to the Stimulation of the fatty function of 

 the liver at the expense of the glycogenic. (This however is not the case with 

 hermit crabs infected with Pcltogaster, for they moult frequently, indicating that 

 the two parasites have different physiological effects.) The reduction of the 

 amount of glycogen, and increase of fat in the liver of infected crabs was shown 

 quantitatively. This regulation of the liver-metabolism in consequence of the ab- 

 straction of fat from the blood by the parasite (or by the ovary in a normal 

 female) suggests a comparison with the theory of immunity, and the author puts 

 forward a provisional hypothesis on the lines of Ehrlichs side-chain theory. The 

 sexual changes w'rought by the Sacculina are regarded as being due to the rege- 

 neration in excess of substances which are continually being absorbed from the 

 blood by the parasite. The sexual characters w'ould then not be produced by an 

 internal secretion of the ovary (hormone theory), but by metabolism induced by 

 the absorptiou of fatty substances from the blood, and their consequent regene- 

 ration in excess ("metabolic Stimulation"). Doncaster (Cambridge).

Die Amphipodenfamilie Corophiiden waren bisher nur als Salzwasserformen, be- 

 sonders charakteristisch für das brackige Wasser, bekannt, wenn man von einer Notiz 

 Zaddcules absieht, die sieh auf den Fund von 3 Exemplaren einer Corophium longicorne 

 (== volutator) im Geserichsee bei Deutsch-Eylau bezieht. 



Verf. fand nun zahlreiche Exemplare einer neuen Art {Corophium devium) an den 

 Pfosten einer Brücke im Müggelsee. Sie leben hier hinter der sich loslösenden Borke, 

 wo sie sich ihre Sandröhrchen bauen. C. Zimmer (München).
