226 BIBLIOGRAPHY OF 1876. 



fragilis: a new genus Limnorea, with two new subgenera, Leucosiu 

 (for four new and one previously named species) and Ligea (eight 

 new species). 



Prof. E.. von Martens in his review points out that several 

 of the new generic names have been preoccupied in Zoology, and 

 in accordance with this view renames Li/nno/ra as Baicalia, 

 Leucosia as Liobaicalia and Ligea as Trachybaicalia. Mr. Dall in 

 his subsequent criticisms amends the spelling of Martens' new 

 genera so as to read Baikalia and Liobaikalia, and supresses the 

 Trachybaikalia, regarding the species of this as the typical form 

 of Baikalia. He regards the whole assemblage of species as part 

 of the old genus Tryonia Stimpson, and regards Baikalia and 

 Liobaikalia as merely subgenera of it; adding another subgenus 

 of his own creation, Dybowskia, the type of Avhich is Ligea ciliata 

 Dybowski.
