CRUSTACEA. 



515- 



certain number of l)ecapoda from Madagascar ; among them are 

 certain species new to the Madagascar fauna. 



1 may refer, in conclusion, to Dr. K. Kossmann's elaborate account 

 of the Malacostraca (Brachyura and Anomura) in the yet incom- 

 plete account of his Exploration of the coasts of the Eed Sea*, 

 wherein the principle of unitiug allied species is carried to a perhaps 

 inconvenient degree, and some modifications in the classification of 

 genera and species are proposed ■which are of doubtful value to the 

 systematist, but which contains much important and useful matter 

 relating to the Crustacean fauna of the Eed Sea. In this work 

 frequent reference is made to a publication (in Eussian, and with 

 Eussian title) by Dr. Paulson, which appeared at Kiew in 1875, but 

 which I have never seent, and which I believe has been quoted by 

 no other carcinologist.
