des Embryo ausgeschiedenen Cuticularhaut im Zusammenhange steht." It has, he continues, 

 the most striking resemblance to " der sogenannten Schalengrube der Mollusken." 

 Having previously observed that, " vorausgesetzt das bei den Orchestien, ahnlich dem, was hei 

 anderen Crustaceen beobachtet wurde, die das Zerfallen des Letters in Dotterschollen 

 hervorrufenden Zellen zum Aufbaue des Mittel-darmes verbraucht werden, nimmt das 

 Entoderm seinen Ursprung von dem Zellen des kugelformigen Organes," Ulianin thus 

 concludes : — "ahnlich wie bei anderen Crustaceen entsteht bei don Orchestien das Mesoderm 

 durch Zersplitterung des Blastoderms, walirend das Entoderm aus vom Ektoderm 

 abstammenden und iu den Dotter einwandernden Zellen zusammengesetzt wird. Die 

 Thatsache, dass die in den Dotter einwandernden Zellen voti den Zellen des kugelformigen 

 Organes abstammen, kanu uns auch nicht sehr befremden : das kugelformige Organ ist, wie 

 oben gezeigt wurde, ein ererbtes verkiimmertes Organ, das seine friihere Bestimmung mit 

 der Zeit verloren hat und dem im Laufe der Zeit neue Funktionen bei der Bildung des 

 Entoderms aufgelegt warden."

A very useful comparative table is given of the terms used by nine authors in describing the 

 mouth-organs and external parts of Amphipoda, omitting mention, however, of the labrum 

 or upper lip. The lahium or lower lip is called lanrjuette by G. 0. Sars, zunge by 

 Dybowsky, Paragnathen by Glaus, but IMerJippe is used by Dybowsky for the second 

 maxillcB, and by Glaus (as an alternative) for the masillipeds. Dybowsky is here said 

 to call the uropoda Schioimnibeine and Springbeine, but that does not quite accurately 

 represent him, since in reality he calls the three pairs of pleopoda ScTiwimmleim, the first two 

 pairs of uropoda Springheine, and the last pair das Steiierhein. It is a mistake also to say 

 that Dybowsky gives metacarpus as an alternative for the " Handwurzel " or wrist of the 

 gnathopods; in fact he gives the word carpus, as might be expected, though for the 

 corresponding joint in the first two pairs of pereeopods he gives " Afterhandwurzel 

 (pseudocarpus)," and in the last three pairs " Fusswurzel (metatarsus)." According to the 

 lists here given, tarsus is used by Glaus and Heller as an alternative for carpus, by 

 Dybowsky as an alternative for Fusstiick (the name which he gives to the hand in the last 

 three pairs of perfeopods), and by Milne- Edwards, iu the form tuvse, as an alternative for 

 doigt or dactylopodite. 



The structure of Goplana polonica is illustrated by Plates X. and XL, of which the explanation 

 is given in French as well as in Polish.
