Moll. 3 
of asymmetry have been considered by Boutan (51), while De Bruyne 
(58) has studied the effect of phagocytosis on development. Deschamps 
(131) has written on the anatomy of the Pulmonata ; Neritina has 
attracted the attention of Lacaze-Duthiers (259) and Lenssen (264, 265); 
Pilsbry and Vanatta (413) have described the anatomy of some South 
American Achatinidce ; while several papers by Paravicini (373-376) will 
repay attention. We may also mention the study by Bottazzi (48) of the 
oesophagus in Aplysia and an interesting note by Fischer (154) on the 
habits of Patella. Drew (142) has written on the Protobranchiata ; Beuk 
(26) has described the morphology of Teredo : Johnstone (230) has given 
an interesting account of Cardium ; and Grobben (183) has dealt with the 
anatomy of Tndacna. Plate (414, 415) has issued an elaborate account 
of the anatomy of the Polyplacopliora ; while Heath (199) has written on 
the development of Ischnochiton. 
Kobelt and Moellendorff (251) have completed their catalogue of a 
portion of the operculated lanclshells; a protest may be made against 
their having issued an index, in the original periodical, which gives 
references to the pagination of the authors’ reprints only, though a key is 
given. Dall (116-118) has written some valuable systematic papers and 
Gude (187) has completed his study of the armature in Plectopylis. 
Brief as are the above notes on the literature relating to the 
recent Mollusca, those relating to paleontology must be still more com¬ 
pressed; we can only point out that the following will be of special 
interest to recent students: Sacco (449, 451), Roman (444), Tate (539), 
and Kennard and Woodward (241). 
As an illustration of the difficulties which beset the Recorder, we may 
note a paper by Popovici-Hatzeg (421): here, quite apart from the 
trouble given by the papers in the volume being separately numbered 
and paged, the numbering of the plates appears to have fallen into utter 
confusion. 
We desire to call attention to a practice, sprung up of recent years, of 
authors writing papers devoted simply to the renaming of genera on the 
ground that the names have already been used. In a number of cases, 
more care would have shewn that there were subsequent names which 
could have been utilized, and in one case in the past year the new name— 
marred on its appearance by a typographical error in its first letter—has 
itself, when corrected, already been replaced, as having been previously 
used in Zoology.
