INTRODUCTION. 
Moll. 8 
Persian Gulf, &c. Pilsbry (492, 493) has published diagnoses of new forms 
from Japan, and Strebel (599) has added to our knowledge of the fauna 
of the Magellanic Region. The Australian fauna has, as in past years, 
formed the subject of papers by Hedley (291, &c.), including an interest- 
ing note on the ' Bassian Isthmus ' as bearing on the present fauna, while 
he has also (293) described some deep water shells from New Zealand. 
Pritchard and Gatliff (505, 506) have continued their work on the 
Victorian fauna. Two papers by IIoyle (312, 313) on Cephalopods may 
also be noticed, one dealing with some species from Ceylon, and the other 
with those collected by the ' Albatross.' 
Anatomical papers have been numerous and valuable. Development 
and Embryology have been studied by Casteel (99, 100), Conklin 
(133-135), FujiTA (237), Glaser (258), Janssens & Elrington (329), 
KosTANECKi (372, 373), Lee (391, 392), Loeb (399), Osborn (461, 462), 
Smallwood (570), Thesing (611), and Wilson (653) and others. The larval 
eye of Chiton has been dealt with by Heath (285), while Mazzarelli 
(431) has written on the free Opisthobranchiate larva. Statocysts in the 
Cephalopods have attracted Frohlich (235), and Grosvenor (269) has 
issued an interesting paper on nematocysts in Nudibranchs. Distaso 
(192) has written on the nervous system of Oscanius, Jordan (342) on 
that of the Pulmonata, while Hyde (318, 319) has dealt with the nerves 
and their endings in the eye of Fecten. Marceau (412, &c.) has published 
several notes on general anatomy, and of the other papers of this class 
we may mention Abric (1, &c.) and Cuenot (159) on Nudibranchs, 
BoissEVAiN (73) on Dentalium, Fleure (226, &c.) on Haliotis, Godw^in- 
AusTEN (260) on Eurystoma, Heath (286, &c ) on the Aplacophora, 
Herdman (298, &c.) on the pearl oyster, Kesteven (350) on Megalatractus, 
Meisenheimer (432) on Desmopteriis, Potzsch (501) on Planorhis, Handles 
(509) on some Trochidce, Simroth (566) on several slugs, Vayssi^ire (629) 
on some Mediterranean Opisthobranchs, and Wissel (656) on the Chitons 
collected by Schauinsland. 
Turning to the more strictly systematic papers, we may notice Dale's 
(171) work on the 'Frog-Shells and Tritons,' with the criticism by Pilsbry 
& Vanatta (498). With Bartsch (172), Dr Dall has also issued a review 
of the Pyramidellidce, including a number of new generic names. Casey 
(98) has described, unfortunately without any review of the family, a 
number of genera in the Pleurotomidce. Other papers of interest include 
Bartsch (35) on Sonorella ; a list of Sphoerospira by Fulton (240), and 
some notes on Arcidoe by Lamy (380, &c.). Hoyle (310) has published a 
key to the recent Dibranchiate Cephalopods, and Grabau (265) has issued 
a very interesting work on the phylogeny of Fusus. 
Variation has continued to prove an attractive subject, Davenport 
(178, 179) having, separately, and with Hubbard (180) continued his work 
on FectfM, Malard (409), Metcalf (445), and Weldon (647) having dealt, 
respectively, with Fatella., Neritina., and Clausilia, while the ever-present 
subject of Helix nemoralis has formed the subject of a work by Lang 
(384). 
Pearls and their formation have been written on by Dubois (202-205), 
Herdman (298, &c.), and McIntosh (404). 
Nomenclature, in the broad sense, has been once or twice the subject of 
serious discussion, and, were the law of the survival of the fittest applied 
to specific names, one cannot help feeling that a small landshell, rejoicing 
in the name of Macrochlamys izushic/iitojimana would be somewhat 
handicapped.
