Bouvier's (19) preliminary account of " Mutations " in certain fresh- 
water prawns is of great interest in connection with current discussions 
on variation and heredity. 
Among the many purely systematic works there may be mentioned the 
series of papers by various authors on collections from the Maldives 
(18 & 207), from Ceylon (34, 127 & 229) and from North Western 
America (87, 165 & 172). 
Important papers on Pycnogonida are published by Carpenter (1), 
Cole (2) and Loman (5 & 6). ' The most interesting discovery however 
is Hodgson's (3) Pentanymphon^ which will necessitate a considerable 
modification of our views on the morphology of the group. 
It may be mentioned that a second instalment of Budde-Lund's 
*' Revision of Crustacea Isopoda Terrestria " has appeared but is not 
included in the present Record since it seems probable that, like the first 
part (Zool. Rec. 1901, Crustacea, No. 25), it may have been published in 
some periodical not yet seen. 
Though this is not the place for an expression of opinion on matters of 
nomenclature, the Recorder may draw attention to the grave danger 
of confusion arising out of the practice, now unhappily becoming common, 
of using old and well-known generic names in a new sense. It would 
greatly facilitate the work of the Recorder, at any rate, if authors who did 
so were careful to indicate in some way the particular genus with which 
they are dealing. To give an example, Miss Rathbun (167) describes 
a new crab under the name of Uca oerstedi. Without a knowledge of the 
particular views which Miss Rathbun held on the subject of nomenclature 
at the date when the paper was published it would be difficult to discover 
to which of two well-known genera the new crab is supposed to belong.
