HIGHLIGHTS OF THE OCTOBER MEETING 
President Fred Cannon expressed thanks to Dorothy Raeihle for her 
considerable efforts in gathering and editing the material from 
which she created the special issue of SHELL CLUB NOTES devoted to 
Karl Jacobson. He also thanked those who assisted Dorothy by sup- 
plying data on Karl's contributions to amateur and professional 
conchology. 
The shells on display represented Harvey Frajlich's good fortune in 
having the opportunity to collect from dredge material generated by 
a beach-widening project in Miami. 
Morris Levine displayed several sea urchin tests, all of different 
species, that he had bought during a recent trip to Thailand. Using 
the light from the slide projector, he demonstrated the beautifying 
effect of internal lighting on these delicately filigreed spheroids, 
and the distinctive color of each species. 
The speaker was Bob Janowsky, who gave the talk that had to be post- 
poned from the September meeting for lack of a projector o His sub- 
ject was "Shells: Formation, Form and Function." Starting with 
drawings, he traced very briefly the path from the earliest single- 
celled creatures to specialized organisms, and then discussed in 
some detail the evolution, in mollusks, of specialized organs and 
body parts, and their functions. Showing photographs of ee : 
shells, he pointed out the features that reveal the adaptations a 
have evolved within this group.
