INTRODUCTION. 
Moll. 3 
f 
. Artificial parthenogenesis has been studied by Loeb (368, 369) ; 
Marceau (378, &c.) has worked on the heart and ifauscles ; Spillmann 
(555) the heart in the Diotocards ; Carlson (86, &c.) the physiology of 
the heart, &c. 
Cephalopod anatomy has attracted a number of workers ; we can only 
mention MertoN (404) on the retina, Hess (278) on the eye, and the 
papers by Schweikart (510) and Joubin (313, 315). 
Amongst the papers dealing with Gastropod embryology may be named 
those of Otto & Tonniges (430) on Paludina , WierzEjski (642) on 
P/iysa , and Schimkewitsch (505, 506) on Philine. Pilsbry (450, &c.) 
has given a useful account of the anatomy of some Helicoids ; Simroth 
(529, &c.) has issued some notes on Slugs; and we record the paper by 
Reyn ell (487) on Cassidaria , as also those of Distaso (184, &c.) on 
Civcidit; and Dentaliim. The Gastropod protoconch has been studied by 
Eesteven (327, 328). A curious case of duplication of the eye in Helix 
lias been noticed by Wiegmann (640). The development of Pelecypods 
has formed the subject of papers by Anthony (11, &c.) ; Lloyd (363) 
has dealt with the boring mechanism in molluscs ; while HerdmAN (275, 
&c.) and Bloomer (49, &c.) have, respectively, written on the anatomy of 
the Pearl Oyster and the Solenidce. The habits and anatomy of the 
Amphineura have been studied by Heath (263, &c.), and we may notice 
the paper by Schweikart (510). 
A review of tho genera of the Mytiliddk has been issued by Jukes- 
Browne (317). Wagner’s (617, 618) studies on Helicina, have resulted 
in a very large number of new names, which may duly be seen in the 
systematic portion. A useful task has been undertaken by May (391) 
who has critically reviewed a number of Tenison- Woods’ ‘ types.’ 
In conclusion, I would desire, since after the present year the form of 
the ‘Record’ will be altered, to take this, the last, opportunity of ex- 
pressing my grateful thanks not only to Mr Edgar Smith, who has kindly 
assisted me for so many years past, but also to those many friends, by 
whose help in furnishing reprints and pointing out errors of commission 
and omission, it has alone been possible to fulfil my task.
