CRUSTACEA. 515 



certain number of Decapoda from Madagascar; among thorn aro 

 certain species new to the Madagascar fauna. 



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

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

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

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

 inconvenient degree, and some modifications in the classification of 

 genera and species arc proposed which arc of doubtful value to tho 

 systematist, but which contains much important and useful matter 

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

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

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

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

 no other carcinolo"ist.
