of molluscs from Japan, which of late years has proved so prolific ; Gude 
(211) has continued his list of the Helicoids of Asia ; and Moellendorff 
(355) has published a further part of his supplement to Semper’s c Reisen.’ 
The attention of workers may also be drawn to a number of scattered 
papers dealing with shells from the Malay Peninsula and the Austro- 
Malayan Region. A posthumous and concluding part of the work on the 
fauna of Mexico and the adjacent region by Fischer & Crosse (172) has 
been published. Taylor (547) has issued the first part of the systematic 
portion of his work on the British fauna, including some very useful maps 
illustrating specific distribution. 
Amongst the more purely systematic papers we may first note the very 
valuable list of names, with references, used in the Colicmbellidce, given by 
Pace (385); an unusual feature being that he has dealt equally with recent 
and fossil molluscs. Kobelt (285) has monographed the Cyclophoridce and 
Gude (210) the Streptaxidce. Some interesting notes on Partula will be 
found in the paper by Smith (498). A new family of Pteropods has been 
described by Meisenheimer (349). Dall (119, 120) has given valuable 
synopses of the Veneracea and Carditacea. Joubin (262) has reviewed the 
Sepiolidce , while the student’s attention may be drawn to a privately 
printed paper by Buckman (61) on some Cephalopods, which contains a 
number of new names. Thiele (550) has dealt with the systematic 
position of the Aplacophora. 
Turning to the morphological work we have to chronicle careful studies 
of Nautilus by Griffin (208) and Willey (591). Hoyle (234) has de¬ 
scribed a luminous organ in Pterygioteuthis , and Steinach (516, 517) has 
given some interesting notes on colour changes in Cephalopods. Pleuro- 
tomaria has been studied by Bouvier & Fischer (56) ; Polygyra and 
Limax by Simpson (483), Lucapma by Illingworth (244), Vaginula by 
Keller (266), Chytra and Limnotrochus by Digby (138) and the Volutidce 
by Pace (384). Pelseneer (395) has written a most valuable work on 
the Pulmonate Gastropods, and Collinge (89, &c.) has given several notes 
on slugs. To Mazzarelli (347) we owe some information on the larval 
Gastropod, while Hoffmann (230) has dealt with the Embryology of 
Nassa. Amongst other papers we may refer to those of Backer (25, 26) 
on the Gastropod eye, Fleure (173) on the Kidneys in Haliotis , Drum¬ 
mond (149, 150) on Paludina , with special reference to Gastropod torsion, 
and Vignon (563) on the cytology of the epithelium. Attention may 
also be called to the notes on sexual dimorphism by Smith (489) and 
Pelseneer (396), while specific variation may be studied in the papers 
by Dimon (139) and Hensgen (223). The Pelecypod hinge has attracted 
Reis (444). A detailed account of the Mytilidce of the Gulf of Naples 
may be found in List (305). Lacaze-Duthiers’ (295) posthumous paper 
on the Morphology of Tridacna and Hippopus may well prove a classic, 
while Carazzi (66) has added to our knowledge of the Histology and 
Physiology of the Pelecypoda. 
Owing to his absence from London, Mr Pace has been unable to assist 
this year. 
The only change made in the ‘ Record ’ has been that the paragraph 
dealing with obituary notices has been broken up, and it is hoped that this 
will now prove more easy to refer to ; the attention of the student is also 
called to the corrections given below (p. 4.)
