PUBLICATIONS: CONE SHELLS: 
A Synopsis of the Living Conidae, by Jerry G. Walls, 1979, T. F. H. 
an ioseiann, Inc., Box 427, Neptune, New Jersey 07753. 1011 pp. 
(352 in color), 309 species fully illustrated in over 1160 color 
photos, indexes of over 1400 living and 1300 fossil names, hardbound 
foie gin Price $30.00 (plus $1.00 for postage and handling when 
ordering direct from the publisher.). 
The publisher's release describes this work by Jerry Walls as "... 
the complete cone book describing and illustrating in color every — 
valid species and their subspecies and major varieties. Each species 
is described in detail, with a summary of variation, a comparison to 
similar species, and a synonymy. An attempt has been made to trace 
all names for living cones back to their original description and 
evaluate them in the light of modern knowledge of the group. This 
has resulted in a clearing away of many questionable names and the 
first attempt at a basic synopsis of the living cone species. 
"The detailed text is written in non-technical language, with empha- 
sis on visible shell characters only. This is the first complete 
set of cone descriptions produced since the classic work of Kiener 
(1845-1850), and it will provide a basic framework for cone studies 
for many years to come. The synonymies are as accurate as possible 
and cover all known valid names based on living cones proposed be- 
tween 1758 and 1976. Many names have been changed and species status 
modified as a result of the research for this book, but all major 
changes are fully explained. 
"Extensive lists of dealer-names and their equivalents, fossil names 
(over 1300), and a complete Synonymic index of over 1400 names of 
living cones supplement the book. A checklist and pricing guide to 
cones is included as an aid in evaluating collections and simplify- 
ing exchanges." 

MALACOLOGICAL ARTICLE OF THE MONTH 
Homing in Cellana tramoserica 
Drs. D. A. Makay and A. J. Underwood discuss the homing of the 
limpet Cellana tramoserica in an article entitled, "Experimental 
studies on homing in the intertidal patellid limpet Cellana tramo- 
serica (Sowerby), published in Oecologia 30: 215-237, duly, 1977. 
Not all limpets return to a home-site. Some move apaund at random 
particularly emigrating from areas of increased density. Homing ’ 
behavior supports the hypothesis that it is an adaptation which 
regulates local density and dispersion to maximize utilization of 
food resources.
