 it is difficult to appreciate the fairness of omitting his name from the title-page. He divides 

 the Malacostraca Edriophthalmata into two orders, Amphipoda and Laimodipoda, the former 

 containing tlie two families, the Gammaridse and Hyjjeriadte ; the latter the two families, the 

 Caprellida3 and Cyamidte. In the Gammaridae, after Talitruslocusta and OrrJiestia littorm, 

 come the following entries.
